  • Patent number: 9178379
    Abstract: Disclosed is a charger for an electric vehicle. The charger includes a connector connected to the electric vehicle, a plug connected to an outlet of the commercial power source, a switching unit to selectively shut off the current according to a temperature of the charger, a display unit to display information about an operation of the charger, and a control unit to control the operation of the charger, wherein the control unit controls the display unit to display two kinds of mutually different information when the current is shut off because the battery is fully charged or the connector is separated from the electric vehicle and when the current supplied from the commercial power source to the electric vehicle is shut off by the switching unit. The charger is prevented from being damaged due to overheat during the charging operation for the electric vehicle.

  • Patent number: 9166429
    Abstract: A universal serial bus charger comprises a universal serial bus connector for providing a connection to a voltage source. An output voltage connector provides a charging voltage to a connected battery. A switching voltage regulator generates the charging voltage responsive to the voltage source. Control circuitry monitors an actual charging current applied to the connected battery and provides a programmed current signal enabling the actual charging current to operate at a programmed level if the actual charging current does not exceed a programmed charging current level. The control circuitry provides a charging current limit signal enabling the actual charging current to operate at a predetermined charge current limit if the actual charging current exceeds the programmed charging current level. PWM control circuitry generates switching control signals to control operation of the switching voltage regulator responsive to the control circuitry.

  • Patent number: 9126488
    Abstract: A charging device for charging a battery (10) by an external power supply (2) includes a temperature sensor (46) for detecting the temperature of the battery, a charger (4) receiving electric power from the external power supply to charge the battery, and a control device (50) controlling the charger such that the battery is charged at a charging rate determined based on the temperature difference between a charging/discharging limitation start temperature and the battery temperature. Preferably, the control device (50) determines the charging rate based on the difference between the amount of charge corresponding to full charge of the battery (10) and the current remaining amount of charge, and the temperature difference. Preferably, the vehicle (100) on which the battery (10) is mounted repeatedly carries out charging and vehicle-running. The control device (50) determines the charging rate according to the temperature increase expected amount when the vehicle runs next time.

  • Patent number: 9112371
    Abstract: Provided are a refresh charging method and a refresh charging apparatus for an assembled battery constituted from lead-acid storage batteries, by which a necessary charging rate may be performed while shortening a charging period. In a constant voltage charging mode, n intermediate threshold values S1 to Sn which decrease stepwisely are set between a predetermined threshold value S0 and a lower-limit current value, and n additional timer periods T1 to Tn are set where n is an integer equal to or larger than one. Counting of the n additional timer periods T1 to Tn is respectively started when the charging current reaches the n intermediate threshold values S1 to Sn. A maximum timer period Tm and the n additional timer periods T1 to Tn are set to satisfy a relationship of Tm>T1> . . . >Tn. Charging is stopped when the counting of one of the maximum timer period Tm and the n additional timer periods T1 to Tn is completed before the lower-limit current value is detected.

  • Patent number: 9065278
    Abstract: Systems and methods for estimating the relative capacity of individual battery subdivisions in a battery system are presented. In some embodiments, a system may include calculation system configured to analyze the electrical parameters to generate derivative values of the parameters over a period of time. The calculation system may further calculate summation values associated with individual battery subdivisions based upon the derivate values. A battery control system may utilize the summation values to generate one or more commands configured to control an aspect of an operation of the battery pack based on using the summation values. The summation values associated with battery subdivisions may be used to determine a relative capacity for storing electrical energy, according to some embodiments. The determination of relative capacity may be used by a control system to prevent over-discharge of a battery subdivision having the lowest energy storage capacity.
