ABB has developed and is demonstrating a high-capacity “flash charging” system for electric buses. The system enables onboard batteries to be charged in 15 seconds with a 400 kW boost at selected stops using a roof-mounted system (“Flash station”). The flash stations are connected to the 50kVA electricity network and also have a 3kWh storage unit (supercap) for smoothing peaks in consumption.
At the end of the bus line (“Terminus station”) a 3 to 4 minute boost at 200 kW tops up the batteries. At the depot station, the bus plugs into a multi-bus supply station connected to the 50 kVA network.
4 minuter, 200 kW blir 13.33 kWh. 400 kW i 15s borde väl bli ca 1.66 kWh. Den kan alltså tas helt från superkondensatorn på 3 kWh som sedan laddas upp för nästa buss/laddning.
Vitsen med detta är att man kan hålla nere batteristorleken i bussarna och därmed spara pengar.
