Abstract
The present invention relates to a system and a method for independently controlling a relay using bimetal which allow bimetal to operate based on a signal output from a micro controller unit when current of a predetermined threshold or more flows on a circuit to allow current which flows between a battery and the relay to flow bypassing the bimetal to independently control the relay regardless of whether a circuit pattern is abnormal.
Claims21
A system for independently controlling a relay using bimetal, the system comprising:
- a bimetal unit configured to be connected with a relay provided in a circuit and shape-transformed by current;
- and
- a switching unit configured to apply specific current to the bimetal unit based on a signal output from a micro controller unit (MCU),
- wherein when a current value on the circuit is more than a predetermined threshold and the micro controller unit thus outputs a first signal,
- the bimetal unit is shape-transformed by the specific current applied from the switching unit and connected with the circuit and the current on the circuit is applied to the bimetal unit to change a state of the relay from an on state to an off state.

A method for independently controlling a relay using bimetal, the method comprising:
- outputting, by a micro controller unit (MCU), a first signal according to whether a current value on a circuit is more than a predetermined threshold;
- applying, by a switching unit, specific current to a bimetal unit;
- being, by the bimetal unit, shape-transformed by the specific current applied from the switching unit and connected with the circuit;
- and
- changing a state of the relay from an on state to an off state by applying the current on the circuit to the bimetal unit.
