New Energy Battery Leakage Case

Battle for the EV Battery Box

Teijin also has been molding some prototype battery-box parts in phenolic resins that resist heat to 1100 deg. C and providing them to customers for testing. According to Foran, another little-publicized issue that EV makers grapple with is battery-pack leakage. This occurs no matter the structural material, he said. To address this problem

A Review on the Recent Advances in Battery Development and Energy

The passage of an electric current even when the battery-operated device is turned off may be the result of leakage caused, for example, by electronically slightly conductive residues of dirt on the battery surface, the battery holder, or mechanical and chemical processes inside the battery . This current flow may also occur within the cell as a result of parasitic electric connections
