AC charging is limited to EV’s onboard charger to convert AC to DC. Therefore if the onboard AC Charger is only rated at 7kW, even if you use an 11kW AC charger, the battery can only be charged at 7kW.
On the other hand, DC Chargers have the capability of converting the AC to DC current and therefore they are able to deliver a higher current and results in faster charging times.
The EV Common Charger Grant (ECCG) co-funds the installation of smart chargers for up to 1% of residential carpark lots (including visitors and handicapped lots & excludes loading bay); rounded-up to the nearest whole number.
For example, if there are 70 parking lots in an Non-Landed Private Residence (NLPR, ie condo), 1% of 70 = 0.7, rounded-up to the nearest whole number equals to 1. 1 charger is be eligible for co-funding.
