Approval of electric vehicle batteries
ECE R100 compliant
Safety, performance and regulatory compliance: a global approach offered by the Emitech Group
The ECE R100 regulation sets out the requirements applicable to Rechargeable Energy Storage Systems (REESS), mainly high-voltage batteries for electric vehicles, to guarantee their safety, robustness and regulatory compatibility. The Emitech Group supports battery manufacturers, builders, approval engineers and quality managers in the complete validation of their batteries, by carrying out all the tests required by the ECE R100 regulations, right up to official approval (E marking).
