ANNEX VII
ANNEX VII PARAMETERS FOR DETERMINING THE STATE OF HEALTH AND EXPECTED LIFETIME OF BATTERIES Part A Parameters for determining the state of health of electric vehicle batteries, stationary battery energy storage systems and LMT batteries: For electric vehicle batteries: state of certified energy (SOCE). For stationary battery energy storage systems and LMT batteries:
1.
the remaining capacity;
2.
where possible, the remaining power capability;
3.
where possible, the remaining round trip efficiency;
4.
the evolution of self-discharging rates;
5.
where possible, the ohmic resistance. Part B Parameters for determining the expected lifetime of stationary battery energy storage systems and LMT batteries:
1.
the date of manufacture of the battery and, where appropriate, the date of putting into service;
2.
the energy throughput;
3.
the capacity throughput;
4.
the tracking of harmful events, such as the number of deep discharge events, time spent in extreme temperatures, time spent charging in extreme temperatures;
5.
the number of full equivalent charge-discharge cycles. 1. Overview
