Product Description

EV Alumina Ceramic Relay Housing / High Voltage DC Ceramic Contactor

 

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. Tesla, Nissan, and Chevrolet are top companies in this new emerging trend. These three companies sell 60% of all-electric vehicles in USA and this figure is expected to increase as climate change and global warming became a major focus. Another biggest advantage of cars running on the electric battery is that they’re low maintenance, thereby ensuring increased efficiency and performance..
