Open-source boards designed in KiCad by nsm81 on GitHub, from 4 repositories. A board’s address here is its repository’s there.
nsm81/VehicleJunctionBox_PCBs
The junction box is an intermediate stage between the accumulator and inverter. It contains an HVD, a current sensor, discharge circuitry, TSAL and TSMPs.
nsm81/VehicleVCU_PCB
A Vehicle Control Unit provides multiple CANBUS transceivers for communication within a vehicle.
nsm81/VehiclePrecharge_PCB
The precharge board contains the precharge resistors, precharge relay, main relay drivers (with economisers), and a controlling micro.
