Automotive PCBA Application Scenarios

1. EV Battery Management System

Widely used in new energy passenger vehicles and commercial vehicles,

the PCBA controls cell voltage sampling, temperature monitoring, charge-discharge 

balance and high-voltage safety management, ensuring stable operation of power 

battery packs and extending battery service life.

2. On-board Charging & Energy Conversion

Applied in on-board chargers (OBC) and DC/DC converters, the assembly supports 

high-current power transmission and signal control, adapting to complex vehicle 

electrical environments and meeting the reliability requirements of long-term charging 

and power conversion scenarios.
