Swiss scientists suggest using the back-up batteries to reduce the load on the power supply at the rapid charging of electric vehicles.
Charge an amount sufficient to overcome 150 km, it will be for 15 minutes, without impacting excessively the grid. 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 �. Power charging station can be up to 4.5 megawatts. 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. On a partial recharge the traction battery Model S sedan takes half an hour, a full charge requires 75 minutes. Related Products :
