  • Patent number: 10124680
    Abstract: An on-board charger for an electric vehicle includes a switch configured to receive an AC voltage, a capacitor connected to the switch and connectable to a traction battery of the electric vehicle, a frequency sensor, and a controller. The frequency sensor is configured to detect during the odd half-cycle of a first cycle of the AC voltage an instantaneous frequency of the AC voltage for the first cycle based on elapsed time between zero-voltage crossings of the odd half-cycle of the first cycle and not based on any other zero-voltage crossings of the AC voltage. The controller is configured to close the switch during the even half-cycle of the first cycle at a first trigger time dependent upon the instantaneous frequency of the AC voltage for the first cycle. The capacitor is enabled to be charged with the AC voltage via the switch while the switch is closed.

  • Patent number: 10107863
    Abstract: A test method for a secondary battery, which early detects the occurrence of the future micro short-circuiting in the screening and promotes to render the contaminant harmless while suppressing the short-circuiting between the positive and negative electrodes in the aging, is provided. This test method includes Step S12 of charging the secondary battery, Steps S13 and S14 of aging the secondary battery in a first pressed state, Step S17 of measuring a battery voltage (V1) after the aging, Step S18 of screening the secondary battery in a second pressed state with a higher pressure than in the first pressed state, and Step S19 of measuring a battery voltage (V2) after the screening. Whether the battery has the internal short-circuiting or not is determined (Step S20) based on the difference between the voltage (V1) measured in Step S17 and the voltage (V2) measured in Step S19.

  • Patent number: 10101401
    Abstract: An energy storage device management method for deciding an SOC estimated value includes: preparing first and second SOC estimation methods for estimating an SOC; and employing a predetermined value as the SOC estimated value when a first SOC region and a second SOC region are different. V-SOC correlation between a voltage and the state of charge of the energy storage device is sectioned into a plurality of SOC regions. The first SOC region is the SOC region that the SOC estimated by the first SOC estimation method belongs to, and the second SOC region is the SOC region that the SOC estimated by the second SOC estimation method belongs to. The predetermined value is set to a value close to a boundary value on a side close to the first SOC region of boundary values sectioning the second SOC region, or a value between the boundary value and an intermediate value of the second SOC region.

    Abstract: A method and system for diagnosing battery system problems in a vehicle, where the method distinguishes between problems of various battery system components. More particularly, battery connection problems such as loose connections, corroded battery terminals, etc., may be distinguished from battery system problems as a whole. Load related readings that generally reflect the performance of the battery system during a cranking event and one or more non-load related readings may be gathered and used to determine whether there is a battery system problem and whether there is a battery specific problem. If load related readings and/or non-load related readings fail to indicate a battery specific problem, a battery connection problem may be diagnosed.
