Battery Management System
BMS is an embedded system which monitors and protects battery pack while enabling it to supply power to power train and peripherrals.
- Dual battery protection: On board: MOSFETS, Off board: GPIO for Contactor.
- On board current measurement.
- Software configurable.
- Power limit estimation.
- Cell voltage monitoring: 14 NMC cells can be with +/- 4.2 mV error.
- Cell balancing current: 200mA.
- Battery current monitoring: Peak measurable current – 160A for 1200s with an error of 1%.
- Battery temperature monitoring: 4 sensors with an accuracy +/- 2.53 deg in the range of (-30 deg to 125 deg) with GPIO for external fan.
