US 2021/0066907 A1 · Fuse Control System And Method Using Defective Mode Detection

Abstract

A fuse control system and method using a defective mode detection, in which an overcurrent protective fuse and a signal fuse capable of performing a function under various conditions in order to protect a circuit are integrated. Thus, it is possible to protect the circuit even in states such as overvoltage, a high temperature, a low temperature, and other dangerous states in addition to an overcurrent state and a short-circuited state. In addition, it is possible to reduce a wide design space and design cost which result from various kinds of fuses being used in series, and to simplify a circuit configuration. Consequently, since circuit resistance is reduced, it is possible to have a positive influence on a battery.

Dependent claims

A fuse control system using a defective mode detection, the system comprising:

an overcurrent fuse which is configured to be fused when a value of a current flowing in a circuit is equal to or greater than a threshold value;
a heat generator configured to generate heat to fuse the overcurrent fuse and that is located sufficiently close to overcurrent fuse to fuse the overcurrent fuse;
a switch configured to change a conduction state of a current applied to the heat generator;
and
a control unitcontroller configured to:
generate a defective mode signal;
and
control an operation state of the switch to turn into an ON state when the defective mode signal is generated,
wherein the overcurrent fuse, the heat generator the switch unit, and the controller are integrated to form a module.
