What Happens When an EV Charger Goes Down at Your Fleet Depot?

An electric vehicle can be ready for its next assignment, but if the charger it depends on isn't working, that vehicle may not be going anywhere.

For fleets running electric vehicles (EVs), keeping the chargers working is just as important as keeping the vehicles maintained. When a charger goes down, it can throw off routes, force last-minute vehicle swaps, and leave fleet managers figuring out how to get everything charged before the next shift.

First, Figure Out What's Actually Wrong

When a charger stops working, the problem isn't always the charger itself. It could be a communication issue between the vehicle and charger, a network connection problem, a damaged connector, or an electrical fault.

• Check the charger's status. Review any displayed error messages or alerts in the charging management platform.
• Determine the scope of the problem. Is one charging port affected, or are multiple chargers at the depot offline?
• Check the vehicle. If safe and permitted by the equipment manufacturer's instructions, try another compatible charger to help determine whether the issue follows the vehicle.
• Review network connectivity. A charger may lose communication with its management system even when electrical power is available.
• Document the failure. Record the charger identification number, error codes, time of failure, affected vehicles, and any troubleshooting steps already taken.

These initial checks can help maintenance providers narrow down the problem before dispatching a technician.

Fleet personnel should not open charging equipment, bypass safety systems, or attempt electrical repairs unless they are appropriately qualified and authorized. Equipment showing signs of damage, overheating, or other electrical hazards should be taken out of service and referred to qualified personnel.

Why Getting a Charger Repaired Can Take Longer Than Expected

According to ChargerHelp's 2026 EV Charging Reliability Report, charging issues resolved with a single work order took a median of seven days to resolve. Problems requiring multiple work orders took a median of 32 days.

The report analyzed approximately 547 million charger data points and 217,000 records covering chargers, sites, work orders, and service issues across a range of charging operations, not just fleet depots. While the findings aren't specific to commercial fleets, they show how quickly repair delays can add up when multiple service visits are needed. Charged Fleet previously reported on the findings.

Reporting a broken charger is one thing. Getting someone out to fix it can be a whole different headache.

Depending on the problem, a fleet might need to work with the charger manufacturer, charging network, installer, electrical contractor, or even the utility. And figuring out who actually owns the problem can eat up valuable time before anyone even starts working on a fix.

Before something breaks, make sure your team knows who to call first, who can troubleshoot remotely, and when to bring in a technician. Someone should also be responsible for following up until the charger is actually working again.

If a charger is covered by a service agreement, review whether that agreement guarantees an initial response, an on-site visit, or actual restoration of service. Those are not necessarily the same thing.

Have a Backup Charging Plan Before You Need One

For a fleet with multiple chargers, losing one charging port may be manageable. For a small depot with only one or two chargers, the same failure could create an immediate scheduling problem.

Know how many vehicles still need to charge, how much energy they need, and whether your remaining chargers can handle the workload.

Depending on the operation, possible alternatives include:

• Reassigning available chargers. Prioritize vehicles with the earliest departures or greatest energy needs.
• Adjusting charging schedules. Stagger charging sessions or extend available charging windows, provided the remaining equipment and electrical infrastructure can support the additional use.
• Using another depot. Fleets operating multiple facilities may be able to temporarily move vehicles to another location with compatible charging equipment.
• Identifying public or shared charging options. Locate suitable charging stations before an outage, including access restrictions, connector compatibility, operating hours, and whether commercial vehicles can physically use the site.
• Reassigning vehicles or routes. Use available vehicles with sufficient charge or substitute another vehicle when necessary.

Public charging may be an option for some light-duty vehicles, but it isn't always practical for commercial operations. Larger trucks and vans may face access limitations, and charging away from the depot can add travel time and labor costs.

Your backup plan should also identify who has authority to change vehicle assignments, approve off-site charging, and communicate schedule changes to drivers.

Understand How Charger Downtime Affects Vehicle Availability

A charger being out of service doesn't automatically mean every vehicle assigned to it is unavailable. The operational impact depends on how much battery charge those vehicles already have, when they're needed next, and whether another charging option exists.

Consider a depot with 10 electric vehicles and five dual-port chargers, each capable of charging two vehicles at once. If one charger goes offline, the depot loses two charging ports, leaving eight available.

That doesn't necessarily mean two vehicles will miss their next assignments. However, the fleet may need to change its charging schedule to accommodate the same number of vehicles with fewer available ports.

Things get trickier when vehicles return at different times, some need more charging than others, and the next shift is already approaching. To get a better handle on how charger problems are affecting your operation, track:

• Charger availability and actual charging-session success.
• Time required to identify and resolve charger failures.
• Number of vehicles affected by charging interruptions.
• Delayed departures or missed assignments related to charging.
• Additional labor, travel, or charging expenses resulting from outages.

The U.S. Department of Energy's Alternative Fuels Data Center recommends tracking charger uptime and utilization. For fleets, it's worth keeping an eye on how often charging problems actually affect vehicle schedules, not just how often a charger goes down.

Who Is Responsible for Fixing the Charger?

Whether you own your charging equipment or use a managed charging service, it's important to know who's responsible when something breaks. Depending on your setup, repairs may fall to the equipment manufacturer, installer, network provider, or maintenance contractor.

The Department of Energy recommends establishing responsibility for maintenance costs and determining whether the site host, charging network, or installer is responsible for service.

Fleet managers should review their contracts to answer several questions:

• Who is the first point of contact when equipment fails?
• Who handles software and connectivity problems?
• Who is authorized to perform electrical repairs?
• Are replacement parts and labor covered by the warranty or maintenance agreement?
• What response and repair timelines are included?
• Who verifies that the charger is working before the service ticket is closed?

The answers should be documented and accessible to the people managing daily fleet operations. Make sure you also review whether maintenance agreements include measurable uptime requirements and procedures for recurring failures.

Build Charger Reliability Into Fleet Planning

When planning new charging installations, think beyond how many vehicles you need to charge today. Can the depot still keep up if one charger goes down? How quickly can equipment be repaired, and are replacement parts and qualified technicians available?

The Joint Office of Energy and Transportation offers resources on reliable EV charging that can help fleets evaluate their infrastructure needs.

Don't overlook basic charger maintenance, either. Regular inspections, proper cable storage, cleaning, and following the manufacturer's maintenance recommendations can help catch problems before a charger goes down.

And don't forget to plan for growth. A depot that can handle one charger being offline today may not have that same flexibility once more EVs enter service.

You can't prevent every charger failure, but one broken charger shouldn't throw off an entire day's work. Know who to call, have a backup plan, and make sure your team isn't trying to figure it all out when trucks are supposed to be heading out the door.
