Buying an electric commercial truck is only part of the electrification equation.

The other part is figuring out where, when and how that truck will charge.

For a fleet with one electric truck, charging may be relatively straightforward. But as the number of vehicles increases, charging infrastructure can become a significant operational, financial and facility-planning consideration.

Fleet owners need to think beyond the charger itself.

Electrical capacity, utility service, charging speed, parking locations, vehicle schedules, future fleet growth and installation requirements can all affect whether a charging project works as intended.

For Southern California businesses considering electric commercial trucks, understanding these issues before purchasing vehicles can help avoid expensive surprises later.  Is an Electric Commercial Truck Right for Your Business? | Tom’s Truck Center | Tom’s Truck Center

Why Charging Infrastructure Matters

With a diesel truck, the fueling infrastructure is usually already there.

You drive to a fuel station, fill the tank and continue working.

Electric trucks operate differently.

A fleet may be able to charge vehicles overnight at its own facility, during scheduled downtime, or during the workday. But that requires the right combination of:

• Charging equipment
• Electrical capacity
• Parking and vehicle access
• Utility service
• Charging schedules
• Software/network management
• Installation planning

And the larger the fleet becomes, the more important that planning gets.

The U.S. Department of Energy recommends considering charging needs when selecting fleet vehicles and notes that charging equipment should be compatible with the vehicles and coordinated with the vehicle provider and charging provider. Alternative Fuels Data Center

In other words: Don’t buy the trucks first and figure out charging later.

1. Start With Your Fleet’s Actual Driving Patterns

The first step in charging infrastructure planning isn’t choosing a charger.

It’s understanding how your trucks operate.

Look at your existing fleet and determine:

• How many miles each vehicle travels per day
• When vehicles leave the facility
• When they return
• How long they remain parked
• Whether vehicles return to the same location every night
• Which trucks need to operate multiple shifts
• How much energy each vehicle is likely to use
• Whether some vehicles could share charging equipment

This information helps determine how much charging capacity you actually need.

For example, a truck that returns to the yard at 6 p.m. and doesn’t leave again until 6 a.m. has a very different charging requirement from a truck that returns at 10 p.m. and leaves again at 4 a.m.

The key question:

How much time does each truck have available to charge?

The answer can be more important than simply asking how large the truck’s battery is.

---

2. Not Every Fleet Needs the Same Type of Charger

There isn’t one universal charger that works for every commercial fleet.

Charging equipment generally falls into different power levels and use cases.

Level 1

Level 1 charging uses standard electrical outlets and is generally too slow to be the primary charging solution for most commercial truck fleets.

It may have limited applications, but businesses considering medium- or heavy-duty electric trucks will generally need to evaluate higher-powered charging options.

Level 2

Level 2 charging provides substantially more power and can be useful for vehicles that have several hours available to charge.

For fleets operating predictable overnight routes, Level 2 may be sufficient for some applications.

The DOE notes that Level 2 equipment can be appropriate for overnight fleet charging, although the exact infrastructure requirements depend on the vehicles and operating schedule. Alternative Fuels Data Center

DC Fast Charging

DC fast charging can deliver substantially more power and can reduce charging time.

That can be particularly valuable when:

• Trucks have short charging windows
• Vehicles need to recharge during the workday
• Trucks operate multiple shifts
• A fleet has fewer charging spaces
• Vehicles need additional energy between shifts

But faster charging generally means more expensive equipment and potentially greater electrical demand.

Faster isn’t automatically better.

The goal is to install the charging capability your operation actually needs.

---

3. Overnight Charging May Be the Simplest Solution

One of the most attractive scenarios for an electric fleet is a predictable return-to-base operation.

Imagine a delivery truck that:

Leaves at 7 a.m. → completes its route → returns at 5 p.m. → parks overnight.

If the truck has enough time to recharge before the next day’s route, the fleet may not need extremely high-powered charging.

Instead, the truck can essentially “refuel” while it is already sitting idle.

That’s an important distinction between commercial EV charging and traditional fueling.

The fleet isn’t necessarily adding a separate activity to the workday.

Charging can become part of the vehicle’s normal downtime.

But that only works if the charging capacity, schedule and electrical infrastructure are properly designed.

---

4. Electrical Capacity Is One of the Biggest Issues

This is where charging infrastructure gets more complicated.

Installing several high-powered chargers can require substantially more electricity than a facility currently uses.

A business might have enough electrical service for its existing building but not enough capacity to support several commercial EV chargers operating simultaneously.

California’s Energy Commission has identified grid capacity as a significant challenge for high-power EV charging, with grid upgrades potentially creating delays and additional costs. California Energy Commission

That means fleet owners should ask:

How much electrical capacity does our facility have today?

And:

How much will we need when we have five, ten or twenty electric trucks?

Those aren’t necessarily the same number.

---

5. Talk to the Utility Early

This is one of the most important pieces of advice for any fleet considering depot charging:

Contact your utility before committing to the project.

Your utility can help determine whether the existing service can support the planned charging load and whether upgrades may be necessary.

Depending on the site, that could involve:

• New electrical equipment
• Service upgrades
• Transformers
• Switchgear
• New panels
• Conduit
• Trenching
• Additional utility infrastructure
• Longer project timelines

The utility serving the property matters, too.

Southern California businesses may fall within the service territory of utilities such as:

• Southern California Edison
• Los Angeles Department of Water and Power
• San Diego Gas & Electric

The earlier the utility conversation begins, the better.

A charger can be delivered much faster than a major electrical upgrade.

---

6. The Charger Isn’t the Only Cost

When fleet owners hear “EV charging infrastructure,” it’s easy to think about the price of the charger itself.

That’s only part of the project.

Infrastructure costs can potentially include:

This is why comparing charger prices alone can be misleading.

A $20,000 charger isn’t necessarily a $20,000 charging project.

7. Plan for the Fleet You Will Have — Not Just the Fleet You Have Today

One of the most expensive mistakes a fleet can make is designing infrastructure around today’s needs without considering tomorrow’s.

Suppose a company plans to purchase three electric trucks.

If management believes the fleet could eventually have 15 electric trucks, the infrastructure strategy should account for that possibility.

That doesn’t necessarily mean installing 15 chargers immediately.

Instead, consider whether today’s project can support future expansion.

For example:

• Can additional chargers be added later?
• Is there enough electrical capacity?
• Can conduit be installed now for future equipment?
• Is the electrical equipment sized appropriately?
• Is there enough physical space?
• Can charging software manage additional vehicles?

California’s statewide ZEV infrastructure planning recognizes the importance of infrastructure deployment for the growing medium- and heavy-duty vehicle market. California Energy Commission

Think in phases.

Phase 1: Initial electric trucks
Phase 2: Additional vehicles
Phase 3: Larger-scale fleet electrification

Planning for expansion now can potentially avoid having to rebuild the infrastructure later.

---

8. Charging Schedules Matter

Suppose a fleet has ten electric trucks and ten chargers.

That sounds simple.

But what happens if all ten trucks return at 6 p.m. and all ten begin charging at the same time?

The facility may suddenly have a very large electrical demand.

A smarter strategy may be to stagger charging.

For example:

6:00 p.m. — Trucks A–D begin charging
8:00 p.m. — Trucks E–G begin charging
10:00 p.m. — Trucks H–J begin charging

The exact schedule depends on the fleet, utility rates, charger capabilities and vehicle requirements.

Charging-management software can also help fleets coordinate vehicles and charging sessions.

The goal isn’t necessarily to charge everything as quickly as possible.

The goal is to make sure every truck has enough energy for the next shift while using infrastructure efficiently.

---

9. Don’t Ignore Electricity Rates

The cost of electricity can vary depending on the utility rate structure and when energy is consumed.

That means when you charge can potentially matter almost as much as how much you charge.

Fleet operators should evaluate:

• Energy rates
• Time-of-use rates
• Demand charges, where applicable
• Peak versus off-peak periods
• Charging efficiency
• Number of vehicles charging simultaneously

This is another reason charging management can become increasingly important as fleets grow.

A fleet that charges intelligently may have a very different energy-cost profile from one that simply plugs every truck in at maximum power the moment it returns.

---

10. Consider Charger Reliability and Redundancy

Here’s an issue that’s easy to overlook:

What happens when a charger doesn’t work?

A diesel fleet generally has multiple fueling options.

A fleet with depot charging may have fewer alternatives.

If a business has five electric trucks and five chargers, losing one charger could potentially affect 20% of its charging capacity.

That doesn’t necessarily mean every fleet needs a backup charger for every vehicle.

But fleet owners should think about redundancy.

Questions to ask include:

• Can multiple vehicles use the remaining chargers?
• Is there a backup charging location?
• Can trucks use public charging if necessary?
• How quickly can a failed charger be repaired?
• Is there a maintenance agreement?
• Does the charger manufacturer have reliable service support?

California is increasingly focusing on charging reliability as infrastructure expands; the CEC says it is developing a statewide EV charging reliability report and has adopted charger reliability reporting and standards regulations. California Energy Commission

For commercial fleets, reliability isn’t a convenience issue.

It’s an uptime issue.

---

11. Public Charging vs. Depot Charging

Fleet owners don’t necessarily have to install all charging infrastructure themselves.

There are two broad approaches.

Depot charging

Vehicles charge at the company’s facility.

Advantages:

• Fleet controls when vehicles charge
• Predictable access
• Can integrate charging into overnight downtime
• Doesn’t depend on public charger availability
• Can be designed around the fleet’s routes

Challenges:

• Significant upfront infrastructure
• Electrical upgrades may be necessary
• Requires space
• Requires planning and maintenance

Public charging

Vehicles use publicly accessible charging stations.

Advantages:

• Less infrastructure investment at the company’s facility
• Useful for longer routes
• Can supplement depot charging
• May provide backup charging

Challenges:

• Availability isn’t guaranteed
• Charger location may not align with routes
• Charging time becomes part of the workday
• Commercial truck compatibility and access need to be evaluated

For many fleets, the answer may eventually be both.

Depot charging can handle the majority of daily charging, while public charging provides additional flexibility.

---

12. Southern California Fleets Have More Infrastructure Options Than They Once Did

The charging network in California continues to expand.

In August 2026, the California Energy Commission approved a $95.2 million Clean Transportation Program investment plan, including $30.2 million specifically for medium- and heavy-duty zero-emission vehicle infrastructure serving areas such as freight, ports, public fleets and school buses. California Energy Commission

California also continues to support infrastructure through programs such as EnergIIZE Commercial Vehicles, which is designed specifically to accelerate medium- and heavy-duty ZEV charging and hydrogen infrastructure. California Energy Commission

For fleet owners, this means the infrastructure landscape is changing quickly.

But it also means funding programs should be treated as moving targets.

Don’t assume a particular incentive will still be available when your project is ready.

---

13. Incentives Can Help — But Don’t Build Your Entire Plan Around Them

California and other programs may provide financial assistance for eligible charging infrastructure.

For example, EnergIIZE Commercial Vehicles was created to provide funding for medium- and heavy-duty zero-emission vehicle infrastructure in California. California Energy Commission

But incentive programs can have:

• Application windows
• Eligibility requirements
• Funding limits
• Equipment requirements
• Project deadlines
• Geographic requirements
• Changing program rules

The best approach is to treat incentives as a potential financial advantage, not as the foundation of your infrastructure plan.

Build a project that makes operational sense first.

Then determine which incentives may apply.

---

14. Consider Smart Charging and Energy Management

As fleets grow, simply plugging vehicles in may not be enough.

Energy-management systems can help determine:

• Which vehicle charges first
• How much power each vehicle receives
• When charging occurs
• How charging is coordinated with electricity rates
• How much total facility power is being used

Some newer charging technologies are also being developed to reduce the impact of high-power charging on the electrical grid.

For example, a 2026 California Energy Commission demonstration of battery-integrated DC fast chargers found that battery buffering could reduce utility demand while still providing high-power charging. California Energy Commission

Not every fleet needs advanced energy-management technology.

But as the number of electric trucks increases, managing electricity becomes part of managing the fleet.

---

15. Don’t Forget the Physical Layout

Charging infrastructure also needs to work physically.

Before installation, consider:

• Where trucks park
• How trucks enter and exit
• Charger locations
• Cable reach
• Turning radius
• Trailer clearance
• Pedestrian traffic
• Safety
• Future charger locations
• Maintenance access

A charger that works perfectly from an electrical standpoint isn’t useful if drivers can’t conveniently connect the truck to it.

This is particularly important for commercial vehicles because they are larger and require more space to maneuver than passenger vehicles.

Design the charging site around the trucks — not the other way around.

---

16. Work With the Truck and Charging Providers Together

The truck and charger need to work together.

Fleet owners should confirm:

• Vehicle charging requirements
• Connector compatibility
• Required charging power
• Recommended charging equipment
• Charging software compatibility
• Network requirements
• Warranty and service support

The DOE specifically recommends confirming charging infrastructure compatibility with the vehicle provider and charging provider before purchasing equipment. Alternative Fuels Data Center

This is another reason why charging infrastructure should be part of the truck-buying conversation from the beginning.

A Simple Charging Infrastructure Checklist

Before adding electric trucks to your fleet, make sure you’ve answered these questions:

Your trucks

☐ How many electric trucks are you planning to operate?
☐ What are their daily mileage requirements?
☐ What are their charging requirements?
☐ What time do they return each day?
☐ How long are they parked?

Your facility

☐ Where will trucks charge?
☐ Is there enough physical space?
☐ Can trucks maneuver easily around the chargers?
☐ Is there adequate electrical capacity?

Your utility

☐ Have you contacted your utility?
☐ Are service upgrades required?
☐ How long could the upgrades take?
☐ What rate structure will apply?

Your charging equipment

☐ Level 2, DC fast charging or a combination?
☐ How many charging ports are needed?
☐ Can chargers be shared?
☐ Is there a backup plan if a charger fails?

Your future fleet

☐ Will you add more electric trucks later?
☐ Can the infrastructure expand?
☐ Is future electrical capacity accounted for?

Your finances

☐ What is the total installation cost?
☐ What will electricity cost?
☐ What maintenance will the equipment require?
☐ Are there current incentives that apply?

If several of these questions don’t have answers yet, you’re probably not ready to order the trucks.

The Bottom Line: Charge Planning Should Start Before the Truck Purchase

Electric commercial trucks can make a lot of sense for the right fleet.

But the truck is only one part of the equation.

A successful electrification plan considers the entire system:

Truck → Route → Parking → Charger → Electrical Service → Utility → Charging Schedule → Energy Cost → Fleet Growth

The biggest mistake is treating charging infrastructure as an afterthought.

Instead, make it part of the truck-buying process from day one.

Before you purchase an electric commercial truck, understand where it will charge, how long it has to charge, how much electricity it will require and what your facility will need to support it.

The right electric truck with the wrong charging plan can still create an operational problem.

The right truck with the right infrastructure plan can become a productive part of your fleet.

Frequently Asked Questions

How much does it cost to install EV charging infrastructure for a commercial fleet?

There is no single price. Costs depend on the number and type of chargers, electrical capacity, utility requirements, construction, trenching, permitting, networking and other site-specific factors. The charger itself is only one part of the total project cost.

Do electric truck fleets need DC fast chargers?

Not necessarily. Fleets with predictable overnight charging may be able to use lower-powered charging equipment. Fleets with short charging windows, multiple shifts or significant in-shift energy requirements may benefit from DC fast charging. The right solution depends on the vehicles and duty cycle.

Can electric trucks charge overnight?

Yes. Overnight charging can be an effective strategy for fleets whose trucks return to the same facility and remain parked for several hours. Whether overnight charging provides enough energy depends on the vehicle, battery, charger and daily mileage.

Does my business need an electrical upgrade to charge electric trucks?

Possibly. It depends on the facility’s existing electrical service and the amount of charging capacity being installed. Larger charging projects may require electrical or utility upgrades, so fleet owners should evaluate electrical capacity early in the planning process.

Should I install one charger per electric truck?

Not necessarily. The appropriate number of chargers depends on vehicle schedules, charging speed, available charging windows and whether chargers can be shared. A fleet with staggered schedules may require fewer charging ports than a fleet in which every truck needs to charge simultaneously.

Can I use public charging instead of installing chargers at my facility?

Possibly, but public charging shouldn’t automatically be assumed to be a substitute for depot charging. Availability, truck compatibility, charging speed, location and charging time all need to be considered. Some fleets may benefit from a combination of depot and public charging.

Are there California incentives for commercial EV charging infrastructure?

California has programs supporting zero-emission commercial vehicle infrastructure, including EnergIIZE Commercial Vehicles. Funding programs and eligibility requirements change, so fleet owners should verify current availability before making financial assumptions.
