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.
