If 5% of South African motorists adopted electric vehicles (EVs) with vehicle-to-grid (V2G) capability, they could help alleviate load-shedding by at least two stages during peak demand periods.
One of the common criticisms against EV adoption in South Africa is that charging these cars could put additional strain on the grid, something South Africa cannot afford amid a severe generation shortage.
EVs require a lot of power to fully charge their batteries, with the typical charging speed on a home-fitted charger with a single-phase connection being 7kW.
That is the same amount of power four to five kettles will draw when running concurrently.
The difference is that an EV needs that power for much longer than a kettle needs to boil water.
That is because they have large battery packs to store enough energy to travel hundreds of kilometres.
