EV Alumina Ceramic Relay Housing / High Voltage DC Ceramic Contactor
1. Description:
The battery pack of electric vehicles are complex and vary widely for each designing company. They combine many individual cells connected in series and parallel to achieve the optimum voltage. Electric batteries for vehicles can contain several hundred cells which are grouped into smaller stacks called modules and then several of these modules are placed in a single pack. The battery packs also contain DC contactors/relays, which connect the battery cells stack to the main positive and negative output terminals of the pack. It also has a variety of temperature, voltage, and current sensors to regulate the environment.
