The battery investigated is a Li-ion HV automotive traction
accumulator with an operating voltage of 130 Vdc, a power
rating of 25 kW, and a total capacity of 9.6 Ah. A dc blocking
device enables the measurement of the RF behavior of the
battery using a VNA. A coaxial adapter is applied for the connection
of the VNA’s Port 1 to the negative pole of the battery
HV−, respectively, Port 2 to HV+.
