Beschreibung
This reference design is a low standby and ship mode current consumption and high SOC gauging accuracy 13S, 48-V Li-ion battery pack design. It monitors each cell voltage, pack current and temperature with high accuracy and protects the Li-ion battery pack against overvoltage, undervoltage, over temperature and over current situations. The SOC gauging, based on bq34z100-g1, takes advantage of an impedance tracking algorithm and achieves as high as 2% accuracy at room temperature. Through a well-designed auxiliary power supply strategy and high efficiency, low quiescent current DC-DC converter LM5164, this design achieves 50-μA stand-by and 5-μA ship mode consumption, saving more energy and allowing longer shipping time and idle time. Also, this design supports a well running firmware, which helps to decrease product research time.
Eigenschaften
- 2% battery pack SOC accuracy at room temperature
- 50-μA current consumption when in standby mode
- 15-μA current consumption when in shipping mode
- Robust and programmable protection, including: cell over voltage, cell under voltage, overcurrent discharge, short circuit, overtemperature and undertemperature
- Support 100-mA cell balancing
- High-side charging and discharging MOSFETs and support pre-discharge function
Typische Anwendungen
- Motor drives, drones
- e-bike battery pack / e-scooter battery pack / Mowing robot battery pack / UPS Li-Ion battery pack / Other over 10S battery pack applications
- Appliances, power and garden tools
