The number of battery cells used in an EV battery pack increases to extend the mileage, which in turn requires a reduction in the volume of battery wiring parts. For the widespread use of EVs, the safety of battery packs is another important factor. This report introduces our development on battery wiring modules for EVs. 1. Introduction
This wiring module is a wiring component used to electrically connect the cell electrodes of the high-voltage battery in series or in parallel. Each wiring module consists of bus bars and wiring harnesses with terminals, both of which are encased in a plastic molding.
Each wiring module consists of bus bars and wiring harnesses with terminals, both of which are encased in a plastic molding. To electrically connect each electrode to a bus bar, the bolt protruding from the battery cell is passed through an opening in the bus bar and then Photo 1.
Here are some common wiring faults and failures in a Battery Management System: Loose connections – Loose or improperly connected wires can result in intermittent connections, voltage imbalances, and inaccurate readings. This can lead to incorrect charge and discharge control, impacting the overall performance of the battery.
The BMS wiring diagram acts as the central nervous system, coordinating various essential monitoring and protection circuits. However, issues in the wiring diagram (10s, 14s BMS wiring diagram, etc.) can lead to undercharged or overcharged cells, unbalanced packs, and even thermal runaway.
Depending on the specifications of the battery pack, various methods can be used to connect the FPC to the bus bar that electrically connects the cell electrodes. A solder connection, which is an example of the bus bar/FPC connection method, is shown in Photo 5. Photo 5. Solder connection between bus bar and FPC
