EV Battery Health Certification
Independent Verification of EV Battery Health
Using embedded modem data from the vehicle, JD Power and Motorq—working directly with OEMs—provide an independent, third-party measurement of EV battery health for current owners, dealers and potential used-EV buyers. This creates a trusted, data-driven view of battery performance throughout the vehicle’s life cycle.
