Charging Infrastructure: Depot, Public, and Home Solutions
One of the most daunting aspects of fleet electrification is powering the vehicles.
cabling, and coordination with Distribution Network Operators (DNOs), often taking 12–24 months and significant expense. Every additional megawatt of capacity can carry a hefty price tag. One UK local authority noted the cost of grid upgrades for fleet charging was “large” for virtually every site they assessed. These challenges are not unique to councils; a private delivery fleet faces the same reality when electrifying a warehouse or logistics depot. Some operators are exploring on-site generation or storage (solar panels plus battery storage) to mitigate grid constraints. In rural areas with weak grids, installing a large battery at the depot to charge from the grid slowly and then fast-charge vehicles from the battery is an emerging solution to avoid prohibitively expensive grid works. Space and layout at depots also need rethinking. Parking lots may need reconfiguration to accommodate charging bays, particularly for larger commercial vehicles that require more room to maneuver and park while connected. Fleets must plan not only for initial charger installation but also future expansion. It’s wise to pre-wire for more chargers than initially needed, anticipating that by 2030 a much greater share of the fleet will be electric. Depot managers also have to implement energy management systems to avoid overloading circuits.
Fleets must ensure their EVs have reliable charging access wherever the duty cycle requires – whether that’s overnight in a depot, during a shift on the road, or at an employee’s home. Establishing a robust charging ecosystem involves a combination of solutions, each with its own challenges and best practices. Depot Charging (On-Site): For many fleets, depot-based charging is the backbone of operations. If vehicles routinely return to a base (or parking yard) at the end of a shift, installing a network of chargers there allows for convenient overnight charging using cheaper off-peak electricity. This approach, often using moderate- power AC chargers (7–22 kW), can ensure every vehicle starts the day with a full battery. However, deploying depot charging at scale is far from trivial. Most depots were never designed for the high electrical loads that dozens of EV chargers demand. Fleet operators consistently cite grid connection upgrades as a pain point: upgrading supply can require new substations,
