Abrégé

A compulsory charging and protective circuit for secondary battery after being over discharged is disclosed. The circuit includes a circuit conducting switch, a releasing unit, a triggering unit and a comparing unit. When the secondary battery is over discharged, a temporary electrical connection is provided by the present invention. The loop of the secondary battery and a charger keeps. When the secondary battery recovers from abnormal status, the temporary electrical connection is called off so that the secondary battery can keep normal operation. Thus, when the secondary battery is under over-discharge, it doesn't have to be unloaded for repair to settle the issue. Maintenance costs can be saved.

Abrégé

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.

A charging device with a 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. A reduction of the voltage of the rechargeable battery is due to self-discharge of the rechargeable battery during standby after being fully charged.
