Abstract: An example energy source for a work machine includes multiple battery cells connectable in parallel to form a battery system having a high pole and a low pole, a load bus to distribute energy from the battery system to the work machine, and a single point of connection between the battery system and the load bus. The single point of connection is a connector including a dual-pole single-throw (DPST) switch. The DPST switch includes a dual-switched circuit path to connect the high pole and the low pole to the load bus, and a single-switched circuit path to provide a switched connection of a high voltage interlock loop (HVIL) circuit.

Abstract: A battery system a first battery module and a second battery module, at least one thermal mat being in thermal contact with at least one battery module, a controller configured to, during a charge cycle, determine that a charge level of the first battery module is out of balance with a charge level of the second battery module and cause a thermal mat to be powered by the first battery module.
