The present invention discloses a method and system for charging rechargeable battery cells in series. When the voltage of a specific battery cell is too high, discharge the specific battery cell, and at the same time let other battery cells with lower voltage continue to charge, so that each battery cell in series can be charged to almost the same level. This invention designs in a “Total voltage follow-up charging method”, a Battery Manage System (BMS) detects total voltage of the series-connected battery in real-time and modifies an “equalizing trigger voltage”, as the total voltage drifts the equaling function still works well.

A portable window controller for operating window lift assemblies of multiple vehicles includes a controller housing that is sized to fit in a hand and a control switch that extends outward from the housing and can be actuated by the hand. The control switch is a momentary switch that is biased toward a home position and terminates power to a regulator motor when the control switch is placed in the home position.

A vehicle battery diagnosis method and system are provided. A controller completes charging a battery by stopping supply of current from a charger to the battery. The controller measures a relaxation voltage corresponding to a decrement of a voltage of the battery during a predetermined time period directly after the charging of the battery is completed. The controller estimates the state of health (SoH) of the battery in accordance with the relaxation voltage.

A capacity judgment module and a capacity calibration method thereof are disclosed. The capacity judgment module is used to judge a capacity of a battery installed in an electronic device. The capacity judgment module includes a database, a voltage detection module and a processing module. The database is used to store the voltage-capacity comparison curve. The voltage detection module is used to obtain a voltage value interval between a maximum use voltage value and a minimum use voltage value of the electronic device so as to divide the voltage value interval into a plurality of levels. The processing module is used to query the voltage-capacity comparison curve to actually modify the plurality of levels of the voltage value interval of the electronic device and the battery capacity ratio according to the voltage-capacity comparison curve, thereby creating a new voltage-capacity comparison table,
