Modular Megawatt Charging
SYSELEK (UK) LTD.
HGV EVs typically have battery packs up to 500kWh, which can be fully recharged in 2 hours with 300kW DC charging. However, this is too slow for many small fleet operators considering converting to an EV fleet. 1MW+ DC charging offers much faster charging, but many small depots are not served by sufficient grid power supply and DNO upgrades will be costly and slow.
This feasibility study investigates modular HGV EV charger designs at a range of power levels, including potential modular power buffer storage to compensate for insufficient grid power supply.
