DEVICE AND METHOD FOR CONTROLLING BATTERY CHARGE AND DISCHARGE QUANTITY IN ECO-FRIENDLY VEHICLE
First Claim
1. A device for controlling a battery charge and discharge quantity in an eco-friendly vehicle, comprising:
- a motor output controller configured to;
determine a primary motor output limit based on information regarding battery state of charge (SOC) and battery temperature;
determine a weighting factor of the primary motor output limit based on information on the battery SOC and battery voltage; and
determine a final motor output limit by correcting the primary motor output limit using the weighting factor.

Abstract
A device and method are provided for controlling battery charge and discharge quantity in an eco-friendly vehicle equipped with a high voltage battery to optimize the battery charge and discharge quantity. More specifically, the device and method prevent limitations of battery low-voltage/overvoltage due to excessive use of electrical energy stored in a battery using battery state of charge (SOC), battery temperature information, and battery voltage information. Additionally, the fuel efficiency and the power performance are improved by securing an additional motor output using existing hardware without addition of parts compared to a related art.
