Nissan LEAFs only charge at 3.6kW, why get a 7.4kW Charger?

Nissan LEAFs were the first mass market city electric vehicle. As such they had smaller batteries and hence a 3.6kW AC charger was appropriate for 24kW hour of batteries. However newer EVs have much larger batteries, hence to charge in a reasonable time, they now come with 6.6kW or 7.4kW chargers. Some EVs are now supporting 3 phase charging at 11kW and 22kW. This trend will continue as battery prices come down and consumer demand for more range of a single charge. 

There is no harm in connecting your LEAF to a more powerful charger. The charger only signals to the EV the maximum power it can draw. Its up the EV to draw as much power as required up to the limit of its onboard AC Charger rating or the maximum as specified by the charger. 

With newer EVs charging at higher rates and with bigger batteries, we believe the small cost increase from 3.6kW to 7.4kW will save you money in the long run, as you won’t have to have upgrade the charger later.
