| 摘要 |
The invention relates to a device/method for the control of a charge operation and the State Of Charge (SOC) of an electrical Energy Storage System (ESS), e.g. a battery, comprising a multitude of cells, said ESS electrically connected to a propulsion system (2) of a vehicle (1) in order to power an Electric Motor (EM). The method comprising the steps of: - Charging the ESS from an electrical power source, e.g. the grid, when the vehicle (1) is at standstill, - Stop the charging when the SOC level of the ESS (SOCEss) is above a maintenance limit for the SOC level of the ESS (SOCML), - Monitoring the battery and/or performing a service operation of the ESS after the ESS has been charged to a SOC level above said maintenance limit for the SOC level of the ESS (SOCML), - Deliberately discharge the ESS to lower the SOC level, and where the SOC level of the ESS (SOCEss) is reduced to a take-off limit for the SOC level of the ESS (SOCTOL) which is set in order to allow the vehicle to be controlled to use regenerative braking for charging of the ESS under subsequent driving when the vehicle (1) is restarted and takes off. |
