Brief Description
SPF-F-36-160
12S / 36V / 160A Smart BMS for 12S*3.2V LiFePO4 battery of golf cart
1. With Graphic User's Interface over SMBus via USB tool kit to PC, to gain battery information, helpful for engineering services., monitoring battery SoC & SoH, such as Amperes, capacity; temperature, protection status and cell balance, event records etc.
2. Conducting back electromotive force (bemf) circuit design..
3. LED display module and tach signal switch, based on Coulomb Counter.(Option)
4. 2-tier system with Mosfet Switch board and monitor-control unit
5. Allowing test vehicle going on slopes of 30° (dgr), multiple surfaces as soft grass and mud
