The proposed standard is limited to Li-ion systems (main or basically only battery chemistry used in EU for these applications). The standard shall include methods for the determination of:
- Rated capacity (in Ah) and rated capacity fade (in %) --> capacity to be used in Wh, not Ah. This is the common reference
- Rated power (in W) and rated power fade (in %) --> rated power fade to be clearly defined and a possible evaluation to be determined
- Internal resistance (in ꭥ) and internal resistance increase (in %)
- Energy round trip efficiency (in %) --> needs to be done application specific
- Expected lifetime (including both calendar and electrochemical ageing)
The measurement tests shall be designed to be relevant for batteries and battery packs intended for the following applications:
- L-category vehicles with traction battery
- All other wheeled personal mobility devices falling out of scope of the L-category vehicles, such as electric bicycles and electric scooters.
