ONYX Battery Management System (BMS) Integrated Battery Battery Management System (BMS manages safe and ecient charging and
balancing of each and all battery cells as a system to maintain battery life and performance)
ONYX Battery BMS Management Scheme The BMS has an overcharge voltage protection function that detects and protects single cells in ad-
dition to serial groupings that will cut o charging to 4.25 V +/- 50 mV (recover at 4.15 V +/- 50 mV).
The over-discharge cuto is 2.8 V +/-80 mV (recover at 2.85 V +/- 150 mV). Also each cell incorpo-
rates PTC and CID protections. PTC (Positive Thermal Coecient) provides external short condition
cell protection, and CID (Current Interrupt Device) provides overcharge condition cell protection.
Battery Load Connector Heavy-Duty Anderson 2-Pole Connector
