TI's affordable Li-ion battery pack reference design for electric motorcycle batteries [Copy link]

The TI reference design presented is a 16S-17S LiFePO4 lithium-ion battery pack design with low current consumption in standby and shipping modes, suitable for backup telecom batteries and electric motorcycles. This reference design is used on a 2-layer PCB. The 9S-15S AFE bq76940 monitors the voltage of the first 15 cells, while the dual-channel general-purpose amplifier LM2904B monitors the voltage of the 16th and 17th cells. With a well-designed auxiliary power strategy and the efficient low quiescent current DC/DC converter LM5164, the design protects the battery pack from overvoltage, undervoltage, overcurrent and overtemperature, and reduces power consumption in standby and shipping modes, allowing for longer shipping and idle time.

Reference design features include:
Cost-effective 16S-17S LiFePO4/Li-ion battery pack solution
±5mV cell voltage sensing accuracy at room temperature for 16/17S cells
100A current consumption in standby mode
5A current consumption in shipping mode
Powerful and programmable protection features including battery over- and under-voltage, over-current discharge, short circuit, over-temperature, and over-cold protection
