ABC-150 The ABC-150 was originally developed to support the design and development of the drivetrain and subsystems of the GM Impact, the first modern electric car. All Webasto power cycling systems are equipped with a real-time clock on the system’s control board that enables measurement of Ah and kWh during cycling. The ABC-150 offers power up to 125kW, with a voltage range of 8 to 445VDC and a current range of ±530ADC. The ABC-150 is used worldwide for the testing of advanced batteries, fuel cells, capacitors and other alternative energy technologies in the automotive, aerospace, stationary power and defense industries.
