BATTERY INFORMATION DISPLAY APPARATUS OF ELECTRIC VEHICLE
First Claim
1. A battery information display apparatus comprising:
- a data storage unit storing battery capacity information according to temperature and current of a battery of an electric vehicle;
an integrated power control unit providing power for charging the battery and driving a motor;
a sensor measuring the temperature and current of the battery; and
a display unit displaying a battery remnant,wherein the integrated power control unit calculates the battery remnant from the battery temperature and current measured by the sensor on the basis of the battery capacity information according to the battery temperature and current stored in the data storage unit and provides the calculated battery remnant to the display unit.
