Interface between Orion Controller and the Tesla 5.3 kWh Battery Pack


(updated 6/12/17)


DSC05879 showing trial placement of the mock up battery module adapter boards that will be used to interface with the Orion BMS system.  The fuses are required to protect both the Tesla sensor lines as well the Orion inputs in the event of either a short or an open circuit.

DMFC01730 of the EVBimmer PC board after adding all the components.  The four terminal screw block on the left connects to the pair of thermocouples (yellow and blue wires of the 5.3 kWh pack) and the eight terminal screw block connects to the voltage sensor lines of the 5.3 kWh pack.

DSC05921  of the EVBimmer control board installed on one of the 5.3 kWh Tesla battery modules.  These prototype boards were manufactured by Advanced Circuits in Aurora, Colorado ( www.4pcb.com) and the total production cost (including components and assembly) for the 8 produced amounted to $54.45 per board.

These boards can be used with an Orion control system for either solar battery charging or for EV charging.  Extra boards have been manufactured and will be available for purchase from www.EVBimmer.com as either the fully assembled board or as a KitPak (picture DSC05919 ).  Feel free to send an email to this blog (sales@narchem.com) for further information.
