Normally, people come home from work and charge their EV immediately. Current grid
systems can handle these new flows in power hardly. Smart Charging means that
you postpone EV charging to timeslots with lower demand. This stabilize the grid
and the EV owner can charge at lower, and even negative prices.
Edmij, together with Sensoria, developed a way to charge at realtime power prices per
quarter of an hour. At September 25th, they initially postpone charging and
starts charging at times with negative prices. Balancing the grid with smart
charging brings benefits to the EV owner and the grid operator: a win-win!
