Chapter 1 Product Applications

BMS is an important part of EV system. Adopting automobile grade components, JDI BI
series can be well extended and widely applied to pure electric and hybrid vehicle, which not
only can detect, manage, control the batteries in single box, but also can be extended through
BMU to manage batteries in several boxes. The series fully meet the systematization
management requirement of the automotive-grade power battery pack. The series is suitable
for LiCoMnNiO2, LiFePO4,Ni-MH, super capacitor and other 0~5v cell.
The product is composed by a Battery Integrated-management Unit (BIU), a display, a
current sensor/diverter, and cables. The series include BI5116, BI5132 and BI5148. Each
BIU can collect and manage 16/32/48 cells, and can be extended to manage 160 cells at most.
The system acquires real-time battery information through Daisy Chain Topology (DCT).
BIU communicates with VCU, intelligent charger, instrument and other device through
CAN-bus. The display shows the real-time information of state, power, SOC etc.VCU
controls the motor through intelligent motor controller after reading BMS information. BIU
can also communicate with intelligent charger and charge pile. There are temperature
measurement of charging interface, CC, CP, CP2 and other required functions
