Workgroup lead: Roland Gagel <firstname.lastname@example.org>
The CARA Battery Health workgroup is established to create common standards to facilitate remarketing and support residual values of used cars through trust in the battery of a BEV, easily to be communicated to buyers, by an independent assessment and certification.
The workgroup aims to deliver what follows:
- Set the standard for a Battery Health Certificate (SOH*) for the remarketing industry in Europe
- Evaluate technology and process options for vehicle individual battery assessment
- Review, validate and real-life test technologies for obtaining SOH data
- Propose a settlement process in case of disputes of buyers (warranty management)
(*) SOH = State of Health in % of original capacity. We use SOH for the State of Health Capacity.
For clarification: SOC = State of Charge is the % the battery is charged with relation to its current capacity. At 100% SOC when SOH is 100%, the battery has the nominal energy available [kwh].
