Abstract
A controller with battery recharge protective function is disclosed in this invention. The controller is used for protecting a battery module. When the battery module is in a protective state, a recharge protection circuit of the controller is activated. A charging current from a positive recharge terminal flows into one pin of the controller. Afterward, the charging current passes the recharge protection circuit, flows out through another pin of the controller, and then returns to a negative recharge terminal. Accordingly, the recharge protection circuit makes the charging current bypass the battery module, so as to prevent the battery module from being damaged.
Claims14
A controller with battery recharge protective function, comprising:
- a first pin coupled to a positive recharge terminal;
- a second pin coupled to a positive terminal of a battery module;
- a third pin coupled to a negative terminal of the battery module;
- and
- a recharge protection circuit coupled to the first pin and the third pin, when the battery module is in a protective state, the recharge protection circuit being activated, such that an in-flowing current at the first pin goes through the recharge protection circuit and out-flows via the third pin.
A controller with battery recharge protective function, comprising:
- a first pin coupled to a negative recharge terminal;
- a second pin coupled to a positive terminal of a battery module;
- a third pin coupled to a negative terminal of the battery module;
- and
- a recharge protection circuit coupled to the first pin and the second pin, when the battery module is in a protective state, the recharge protection circuit being activated, such that an out-flowing current at the first pin in-flows from the second pin and goes through the recharge protection circuit, so as to out-flow via the first pin.
A controller with battery recharge protective function, comprising:
- a first pin coupled to a positive recharge terminal;
- a second pin coupled to a positive terminal of a battery module;
- a third pin coupled to a negative terminal of the battery module;
- and
- a voltage-clamping circuit coupled to the first pin and the third pin, the voltage-clamping circuit being configured to maintain a level of the first pin to be equal to or lower than a sum of a level of the second pin and a predetermined level difference, wherein the predetermined level difference is positive.
