Design Guide: TIDA-010030  
Accurate gauging and 50-µA standby current, 13S, 48-V  
Li-Ion battery pack reference design  
Description  
Features  
2% battery pack SOC accuracy at room  
temperature.  
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. This  
reference design was implemented for a 2-layer PCB.  
Also, this design supports a well running firmware,  
which helps to decrease product research time.  
50-µA current consumption when in standby mode  
5-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  
Applications  
e-bike battery pack  
e-scooter battery pack  
Mowing robot battery pack  
UPS Li-Ion battery pack
