EV Guard Oy manufactures battery guards for hybrid and electric vehicles using 3 mm marine aluminum and 8 mm recycled PET composite to protect battery packs, liquid-cooling systems, and electrical connectors. The guards distribute impact force, reduce temperature fluctuations, improve energy efficiency, and are 100% recyclable. The company supplies guards to authorized repair shops. No valid regulation currently applies to aftermarket battery shields; UN R100 does not cover this product, representing a structural gap in regulation.
