Description

EV Alumina Ceramic Relay Housing / High Voltage DC Ceramic Contactor

1. Description:

For the 160,000km drive limit, there is an assurance of 8 years of battery life. Automakers are trying to extend the overall warrant to almost 10 years. By 2020, the United States Advanced Battery Consortium (USABC’s) has set a target of 1000 cycles for 15 years. For 250 km daily, 2000 cycles with an overall 500,000 km are considered a good approach for an EV battery. Many experiments have been performed regarding this research and acceptable outcomes have been observed.

2. Feature Advantages:

1) Anti corrosion

2) Abrasion resistance

3) Impact resistance

4) High precision

5) High stability

6) Satisfy various technical requests
