  • Patent number: 9362758
    Abstract: A method for reducing a total loss of charge of battery cells by balancing states of charge includes checking boundary conditions as to whether a vehicle is in the park mode, whether a previous balancing step occurred in the past by at least a defined time period, whether a temperature of a balancing unit lies below an adjustable temperature limit and whether states of charge of all battery cells exceed a minimum state of charge. Additionally, the method includes determining a need for balancing such that a check is made as to whether a maximum difference of all states of charge of all battery cells is greater than an adjustable limit state of charge. Also the method includes, balancing by the balancing units if the first two steps of the method are affirmed. The balancing resistances are connected to respective battery cells for a predetermined time.

  • Patent number: 9356452
    Abstract: A method for reducing a total charge loss of battery cells by equalizing states of charge includes making an initial check as to whether a temperature of at least one balancing unit lies below a preselectable temperature limit. Thereupon a check takes place as to whether a charging process of the battery cells has completed and the state of charge of the battery cells is >90%. A determination then follows as to whether a maximum state of charge difference between battery cells lies above an adjustable limit (DELTA_SoC).

  • Publication number: 20140338884
    Abstract: A cooling system includes a coolant circuit, and a cooling apparatus positioned in the coolant circuit. Coolant flows through the cooling apparatus so as to control a temperature of a battery positioned in a chamber volume. The cooling system further includes a regulating device configured to regulate a temperature of the cooling apparatus. The cooling system has an element configured to determine a dewpoint temperature prevailing in the chamber volume, and the regulating device is configured to use the element to regulate the temperature of the cooling apparatus such that the temperature of the cooling apparatus is higher than the dewpoint temperature prevailing in the chamber volume.
