- the state of charge threshold SOCmin_PA may be equal to 65% of SOC_B
- the state threshold load SOCmin_PA may be equal to 80% of SOC_B.
- Function block B23 activates an output Y when the state of charge SOC_B is greater than the calibrated state of charge threshold SOCmin_PA.
- This active output Y of block 23 indicates to the process that the residual charge in the STK12V electric storer has not reached a critical threshold for starting the vehicle and that the latter would be able to supply electrical consumption via the accessory sockets PA.
- the functional block B23 activates an output N which indicates to the process that the charge present in the electric storer STK12V must be kept for a future start of the vehicle. The process then decides that the STK12V electrical store is no longer able to supply electrical consumption via the PA accessory sockets and stops using it.
- the present invention allows better control of the energy management of the low-voltage on-board electrical network in a vehicle and, more particularly, in an electric vehicle, so as to avoid a starting failure due to an excessive discharge of the storage device. low voltage electricity.
