An individual CAN bus connects the two packs together, such that they’re treated as one battery. The operator doesn’t see battery one and battery two; they just see one battery capacity.” The vessel’s control systems and various other electronics run off a lowerlevel, 24 V bus, enabling compatibility with the 10-30 V range of most of the USV’s non-powertrain subsystems. Two battery packs from Victron Energy sit in the electrical racks and power the 24 V bus – one in the forward rack and one in the stern rack – even though each battery is capable of powering both racks. Each Victron pack is a turnkey, COTS system, built around LFP cells, and it has its own BMS and sensors. Thermal management The efficiency of the USV’s components, along with being surrounded by splashing sea water, means that most active cooling is only required when the batteries are being charged. “Usually, you think of battery discharge being a huge source of heat, but because we want to fast-charge at 22 kW using a three-phase AC input that actually Kort designed Pioneer’s keel coolers to optimally handle when customers max out the power consumption of onboard systems ~ ~
