  • Patent number: 10302709
    Abstract: A battery is subjected to a discharge current pulse that is normalized to its capacity. The battery voltage is measured before, during and after the pulse, and various parameters are calculated therefrom. The parameters are adjusted depending on both the value of the nominal or maximum cut-off voltage of the battery and on its open circuit voltage prior to the pulse. Based on the open circuit voltage, one of multiple different analysis paths is selected, each representing a different state of charge range. The analysis selected involves a comparison of the adjusted parameters with a set of thresholds that are specific to the selected analysis and that depend on the desired cut-off point between good and poor state of health. Batteries of different nominal voltages, capacities and chemistries can be tested without knowing their state of charge and without the tester having been calibrated for a specific battery model.

  • Patent number: 10180460
    Abstract: A characteristic, such as State Of Health (SOH) or State Of Charge (SOC), is estimated for an Energy Storage System (ESS) by supplying a pre-determined signal to the ESS, measuring a response signal output by the ESS, and obtaining an impedance spectrum of the ESS. In one example, the ESS is one of several electrochemical battery packs of an electric vehicle. The pre-determined signal is a current signal generated by a switching power converter that transfers charge from the battery pack to other battery packs or transfers charge from the other battery packs onto the battery pack. The pre-determined signal is generated without disrupting any load supplied by the battery packs. The battery pack outputs a voltage signal in response to receiving the pre-determined current signal. A processor obtains an impedance spectrum using the current and voltage signals, and thereby obtains an SOH and SOC estimate of the battery.

  • Patent number: 10131235
    Abstract: A method operates a charging connection device for electric vehicles, the charging connection device including a housing inside which at least one temperature sensor constantly senses at least one temperature value. As an essential feature, the maximum permissible charging current is reduced to a specific value greater than zero if a first threshold temperature of a first temperature value is exceeded and the charging process is interrupted if the first threshold temperature has been continuously exceeded by the end of a first interval or when the at least one temperature value exceeds a second threshold temperature of the at least one temperature value. The proposed method of operating a charging connection device for electric vehicles provides for greater availability, better fault tolerance of the charging connection device while ensuring lower production costs.

  • Patent number: 10116160
    Abstract: A charging circuit for a bootstrap capacitor comprises a P MOSFET having a body diode and an N channel power MOSFET also having a body diode. The drain of the P MOSFET is coupled to the source of the N channel power MOSFET, and the source of the P MOSFET receives current from a vehicle's battery. The gate of the P MOSFET receives a control signal for turning the P MOSFET either on or off and the drain of the N channel power MOSFET is connected to a bootstrap capacitor The P MOSFET's body diode prevents current flow from the battery to the bootstrap capacitor when the P MOSFET is turned off and the N MOSFET's body diode prevents current flow from the bootstrap capacitor to the battery when the N MOSFET is turned off. The use of a power MOSFET device with its low ON resistance ensures that the capacitor is charged to a sufficiently high voltage even under low battery conditions.

  • Patent number: 10052961
    Abstract: A nonaqueous electrolyte secondary battery is a battery system for an electric vehicle which prevents high rate deterioration. An integrated evaluation value which is a deterioration index value of high rate deterioration is subjected to correction processing reflecting a recovery behavior of the high rate deterioration during charging/discharging deactivation in a battery deactivation period. The correction processing is executed according to a relaxation coefficient indicating the degree of relaxation of deviation of an ion concentration each time a given time elapses when the battery deactivation period ends. The relaxation coefficient is set variably such that, when a time length of the battery deactivation period is short, the degree of relaxation of deviation of the ion concentration for the given time becomes greater than that when the time length is long.
