BATTERY CHARGE STATE CONTROL DEVICE FOR HYBRID VEHICLE Russian patent published in 2019 - IPC B60L50/15 B60W20/13 B60L3/08 B60L15/10 B60R16/33 

FIELD: machine building.

SUBSTANCE: invention relates to a device for controlling accumulator battery charge state for a hybrid vehicle. Vehicle comprises an internal combustion engine, an electric motor, a storage battery and a charge state control device. Vehicle is configured to: accumulate battery from ICE, movement from electric motor, charging accumulator battery from external power supply. Control device comprises electronic control unit configured to: 1) setting the target degree of charging, wherein the target charging degree is the target state of the battery charge state when the hybrid vehicle arrives at the prescribed charging station; 2) controlling the output power of the internal combustion engine and the electric motor so that the charge state at the time when the hybrid vehicle arrives at the charging station has a target charging degree value; 3) estimating the charging probability and setting the target charging degree lower when the estimated charging probability is higher than when the estimated charging probability is low, wherein the charging probability is the probability that the storage battery is charged from the external power source at the charging station when the hybrid vehicle arrives at the charging station.

EFFECT: optimization of battery power consumption is achieved to reduce the ICE operation depending on the distance from charging stations.
