Swiss scientists suggest using the back-up batteries to reduce the load on the power supply at the rapid charging of electric vehicles. Â
Charge an amount sufficient to overcome 150 km, it will be for 15 minutes, without impacting excessively the grid. Â To charge 200 electric vehicles per day will be enough stations with backup batteries such as lithium-iron, which occupies the volume of no more than four shipping containers for transportation of cargo and provides up to 2.2 megawatt hours of electricity •. Â Power charging station can be up to 4.5 megawatts. Â To recharge an electric vehicle traction battery charge directly from
the home network, it takes about 8 hours but the power of the charger at the same time does not exceed 3-4 kW.
Tesla Motors company its fast charging stations using direct current by passing up to 120 kW. Â On a partial recharge the traction battery Model S sedan takes half an hour, a full charge requires 75 minutes. Â Related Products :
