Product Description

EV Alumina Ceramic Relay Housing / High Voltage DC Ceramic Contactor

 

1. Description:

As the automobile industry is getting advanced, it is expected that the Electric Vehicle (EV) adaption is going to accelerate in the coming decade. Major concerns of the EV industry is; improved manufacturing, lower pricing, and public awareness. The Electric Vehicle (EV) introduces new demands on their battery with these new responsibilities, the modern energy source works extremely well. A question may arise in your mind that why does a phone battery have a life span of three years while that of an EV is 10 years or more? Nobody knows the answer, but progress and advancement have been made in the industry regarding this scenario. The matter of economically storing electrical engineering is still an unsolved challenge in the modern era. You already have the idea that the battery is the main component of the EV. You will understand some basics of the battery in this article with the realization of some factors that are responsible for the aging of the battery and some developments being made for the betterment of EV batteries.
