Traction battery power wiring

The 72V battery pack was wired keeping in mind that the wiring should be able to provide up to 400A for short periods. Most of the connections were done using power terminal connectors purchased togheter with the batteries from www.ev-power.eu. As the batteries were not assembled side to side, most of the power terminal connectors were too short and their holes had to be slightly modified to make the connections possible.

A 400A 75mV shunt resistor was mounted on the negative terminal of the battery pack to allow battery current monitoring. A 400A ANL type fuse was mounted as close to the positive terminal as possible. The cables used have a cross section of 50mm^2.

The battery management electronics will be wired next followed by the first charging of the traction battery pack.
