    Abstract: An automatically generated and customized fast charging process results in reduced degradation in the battery cell. An algorithm for a particular battery cell profile is automatically generated and customized to minimize degradation due to fast charging for that particular batch. To generate the custom algorithm, battery cell information is retrieved for a profile of a battery, wherein each battery profile may have a particular manufacturer, model, type, electrode batch, and potentially other specific identification information. Each battery cell is charged from a particular SOC level and at a selected C-rate, and then discharged. During discharge, the battery cell is monitored for detection of lithium plating or other undesirable effects. A lookup table is automatically generated from the battery cell information, and can be provided to devices and/or battery management systems. The BMS then uses the lookup table to apply a charging process that is customized to the on-board battery.

  • Patent number: 10990116
    Abstract: There is provided a power management device including a load current control unit that sets an upper limit on a load current received from a connected feeding device and controls the load current on the basis of the upper limit, and a determination unit that, when the load current control unit has reset the upper limit to a higher value, determines if the upper limit has exceeded a current capacity of the feeding device on the basis of a voltage drop level of an input voltage. The load current control unit resets the upper limit in increments or decrements of a predetermined value, and the load current control unit, when the determination unit has determined that the upper limit had exceeded the current capacity of the feeding device, controls the load current by resetting the upper limit to a value not exceeding the current capacity.

  • Patent number: 10988045
    Abstract: A method for detecting charging current curves for electric vehicles at charging stations. In the method, a charging current curve is captured at a charging station, and the charging current curve is stored together with a vehicle identification of the charging vehicle. For each respective vehicle identification, a charging current curve at a plurality of charging stations is stored, and for the respective vehicle identification, a present charging current curve can be compared with the stored charging current curves at the plurality of charging stations. In the event of a deviation of the present charging current curve from the stored charging current curves at the plurality of charging stations which is greater than a threshold, a signal is output.

  • Patent number: 10992170
    Abstract: A power supply apparatus and a power supplying method thereof are provided. The power supply apparatus includes a power switch and a supplied power generator. The power switch respectively receives a first power and a second power through a first switch and a second switch. The supplied power generator converts the first power or the second power to generate a supplied power. When the supplied power generator judges the first power being cut off, during a first time period, the first switch is cut off and a voltage converting operation of the supplied power generator is stopped. During a second time period, the second switch is turned on, and the voltage converting operation of the supplied power generator is restarted after the second switch being turned on.

  • Patent number: 10985644
    Abstract: An integrated circuit (IC) comprises a regulator circuit, a bootstrap control circuit, and a gate driver that drives a transistor pair in buck or boost mode to switch current through an inductor. The IC has a VIN terminal coupled to receive a voltage generated from an AC power source, a STR terminal coupled to receive a voltage from a stored power source (e.g., a capacitor bank), and a HSB terminal that is capacitively coupled to the inductor. When bucking or boosting, the regulator circuit generates VDD supply voltage from the stored power source, supplies the VDD supply voltage onto the bootstrap control circuit, and the bootstrap control circuit generates a gate driver supply voltage that is supplied to the gate driver circuit. When not bucking or boosting, voltage on the HSB terminal is maintained between a voltage threshold from the AC power source without draining the stored power source.
