| TSB009323 | 2023-12-26. Service bulletin. ELECTRICAL SYSTEM:PROPULSION SYSTEM:TRACTION BATTERY. TSB: Battery Electric Vehicles (BEVs) store electricity received via an external power source in the BEV traction battery. When the BEV is not used for a period of 30 days or more, the traction battery self-discharges, thus reducing vehicle travel range. To prevent the BEV traction battery from fully discharging it is necessary to maintain the charge level of the BEV traction battery. |
