|20150077039||CHARGING STATION HAVING BATTERY CELL BALANCING SYSTEM - A charging station which has a battery cell balancing system is disclosed. The charging station includes: a number of balancing charging units, each has: a detecting element for detecting a state of charge of a battery cell; and a charging element for processing charging to the battery cell; a power unit for providing electric power; and a charging control unit, linked to the balancing charging units, and the power unit, for controlling the electric power from the power unit to the charging element to charge the battery cell. The battery cell is linked in serial or parallel with other battery cells in a battery pack. The charging control unit stops the power unit to charge the battery cell when the state of charge of the battery cell detected by the detecting element is full or exceeds a predetermined value.||03-19-2015|
|20140097668||CHARGING SYSTEM FOR ELECTRIC VEHICLE - A charging system for an electric vehicle is disclosed in the present invention. It includes a rechargeable battery module, a motor driver, a power switch, and a control circuit. The motor driver stops outputting electric power from the rechargeable battery when the control signal from the control circuit is received and keeps outputting electric power from the rechargeable battery when the control signal doesn't exit. The design of the present invention is in a series connection. It can not only be charged simultaneously, but also control the drive motor to stop running. Danger of hard acceleration of the motor due to charge can be avoided.||04-10-2014|
|20130342172||CHARGING DEVICE WITH BATTERY MANAGEMENT SYSTEM FOR RECHARGEABLE BATTERY - A charging device with battery management system which remains a rechargeable battery in full capacity during standby after being fully charged is disclosed. The charging device includes a charging module, electrically connected to a power source, for charging the rechargeable battery; a voltage detecting module, for detecting a voltage of the rechargeable battery; and a determination module, for instructing the charging module to charge the rechargeable battery with a supplementary current when the voltage of the rechargeable battery detected by the voltage detecting module reduces to a first predetermined voltage until the voltage of the rechargeable battery reaches a second predetermined voltage. Reduce of the voltage of the rechargeable battery is due to self-discharge of the rechargeable battery during standby after being fully charged.||12-26-2013|
|20130264996||DETACHABLE MODULIZED BATTERY CHARGING ASSEMBLY - A detachable modulized battery charging assembly for electric vehicles is disclosed.
