Customized dielectric Sealed Large Capacity DC Relay Ceramic Shell For Car Battery
Charging
1. Description:
Electric vehicles (EV) uses traction motors for moving force. These
vehicles may be powered through off-vehicle batteries or may
contain an electrical battery, fuel cells, or solar panels to
convert fuel to electricity. This technology was introduced in the
19th century and for years it has been used to power trains. In modern
times, with the increased focus on renewable energy and reducing
carbon footprints, electric cars have come to the spotlight.
2. Feature Advantages:
1) High compressive strength.
2) Anti corrosion
3) Abrasion resistance
4) Impact resistance
5) High precision
