  • Patent number: 10889197
    Abstract: Methods for monitoring the state of charge of a battery of a motor vehicle are disclosed in which the battery current is determined at moments at which the battery charging voltage has decreased to a defined limit value. The battery current thus determined is transmitted to an evaluation unit, which generates an alarm signal if no discharge of the battery is measured by means of the determined battery current in a defined period. The limit value for the decrease of the battery charging voltage is selected such that the algorithm as a result can identify whether the state of charge of a battery lies above or below a threshold above which a certain electrical functionality of the battery can be guaranteed.

  • Patent number: 10886755
    Abstract: In a power control system, a server transmits to each facility data generated by estimating a variation with time in power consumption in each facility and an upper limit value of power capable of being supplied to each facility. A HEMS controller calculates the sum of amounts of electric power consumed over an upper limit value on the basis of estimation data. A power conditioner reserves the power corresponding to the result of calculation in a storage battery in advance. The power conditioner supplies the power corresponding to the power storage capacity reserved in the storage battery to the facility in a case where the power consumption in the facility exceeds the upper limit value such that the upper limit of the power to be supplied from the system to the facility is set to the upper limit value.
