In order to guarantee a maximum service life for high-voltage batteries and to avoid any consequential damage, the high-voltage batteries should be maintained in accordance with the specification.
Use case/charge specification | Maximum non-operational time 6 weeks | Maximum non-operational time 12 weeks | Non-operational time > 12 weeks (inventory vehicles) | Vehicles in showrooms |
High-voltage battery (on electric vehicle) | Before the non-operational time: If the charge level (SOC) of the high-voltage battery is < 30 %, the high-voltage battery must be charged to an SOC value of approx. 50 %. | Before the non-operational time: If the charge level (SOC) of the high-voltage battery is < 30 %, the high-voltage battery must be charged to an SOC value of approx. 50 %. | Before non-operational time and then every 6 months: If the charge level (SOC) of the high-voltage battery is < 30 %, then the high-voltage battery must be charged to an SOC value of approx. 50 %. | Before non-operational time and then every 2 months: If the charge level (SOC) of the high-voltage battery is < 30 %, then the high-voltage battery must be charged to an SOC value of approx. 50 %. |
Note: The non-operational time must be deducted from ASSYST manually because the service computer only operates under power.
In the case of new vehicles, make sure that transport mode is activated, i.e. until the delivery inspection immediately prior to handover to the customer.
Transport mode can be reactivated (after service in the showroom) up to 350 km. Before activation, the vehicle with connected 12 volt battery must be charged.
