Abstract
A battery management apparatus includes a shunt resistor connected to a battery and a voltage generation unit configured to generate a first output value and a second output value which have a difference therebetween corresponding to a magnitude of a voltage applied to the shunt resistor, in which the difference between the first output value and the second output value corresponds to the magnitude of the voltage applied to the shunt resistor when charging over-current or discharging over-current flows in the shunt resistor.
Claims14
A battery management apparatus comprising:
- a shunt resistor connected to a battery;
- and
- a voltage generator configured to generate a first output value and a second output value,
- wherein a difference between the first output value and the second output value corresponds to a magnitude of the voltage applied to the shunt resistor when charging over-current or discharging over-current flows in the shunt resistor.
A battery management apparatus comprising:
- a shunt resistor connected to a battery and positioned on a charging/discharging path of the battery between a first node and a third node;
- a first resistor connected to the shunt resistor at the first node;
- a second resistor connected to the first resistor at a second node;
- a third resistor connected to the shunt resistor at the third node;
- a fourth resistor connected to the third resistor at a fourth node;
- a first switch connected in series between the second resistor and ground;
- a second switch connected in series between the fourth resistor and ground;
- and
- circuitry configured to receive a voltage of the second node and a voltage of the fourth node and to determine whether over-current flows in the shunt resistor based on the received voltages.
