  • Patent number: 11209491
    Abstract: The invention provides an estimation method for state of charge (SOC) of battery. A reference SOC is inquired from a look-up table based on a voltage of battery detected. A voltage threshold is subtracted from the voltage of battery to obtain a voltage difference. A current SOC or the reference SOC is divided by the voltage difference to obtain a first slope or a second slope. The first slope is divided by the second slope to obtain an adjustment ratio. An electric charge capacity for charging the battery is counted by a coulomb counting method to obtain a count capacity of discharging that is multiplied by the adjustment ratio to obtain an adjustment value. The adjustment value is subtracted from a previously recorded remaining capacity to obtain a new remaining capacity. The new remaining capacity is divided by a full charge capacity to estimate a new SOC of battery.

With these maximum charging currents, the battery cells are then simultaneously charged during a charging time t (t?1/C) predefined by the C-factor.

  • Patent number: 11100433
    Abstract: A method for the optimized use of a parking area. Vehicles which are to be parked on the parking area are each assigned a parking space, the vehicles navigating to the respective assigned parking space, in particular autonomously. Furthermore, vehicles may carry out a change of the parking space in order to enable an improved use of the available parking area or a faster availability of the vehicle, whereby overall an optimized use of the parking area is achieved. Initially, an available range of the respective vehicles is ascertained, and the assignment of the respective parking space and/or a possible change of the parking space are made dependent on the available range of the individual vehicles. The available range of a vehicle is in particular described by a residual fuel amount or a charge state of the vehicle.
