Hardware

• BPath BMS;
• 50 Ohm, 50 Watt pre-charge resistor;
• 3.5 Inch Color Touch Screen;
• 18-53VDC power supply;
• 400 Amp Gigavac contactor;
• On/off button with color LED ring;

Functionality

• Balancing Cell
• Contactor tripping at high cell voltage or low cell voltage, high module temperature;
• Error message high temperature, low temperature, high cell voltage, low cell voltage, too large difference between cell voltages;
• Preloading;
• State-off-charge indication. Readout via display and the LED ring changes color from green to red depending on the filling of the battery;
• Readout of the 6 cell voltages and the 2 temperatures in each Tesla module;
• Battery voltage readout;
• BMS information via Canbus on Victron network: temperature, errors, SOC, voltage.

Extra functionality for Victron GX networks (this is not mandatory, the BPath BMS does not depend on a charger/inverter brand. It will balance the Tesla battery and switch off consumers/chargers in unsafe situations):

• Temperature dependent charging current from Victron compatible chargers, low temperature low charging current. High temperature reduces the charging current;
• Victron charging voltage adjustable from BPath BMS;
• Storage mode, for the period when the battery is not used. Reduced charging voltage for extended life, for Victron compatible chargers.

Interfaces 

• Communication with Tesla Battery Monitoring Board;
• CAN Bus communication with Victron GX chargers;
• Potential free changeover contact for charge enable;
• Heat enable, cool enable.
