Abstract

A battery temperature control system includes: a memory storing a maximum charging current map according to temperature of a battery for an electric vehicle, and an allowable current map according to a control pilot (CP) duty; and a temperature controller comparing a maximum charging current corresponding to a current temperature of the battery with an allowable current corresponding to a current CP duty to determine whether to increase the temperature of the battery.

Claims (7)

1. A battery temperature control system, comprising:

a memory storing a maximum charging current map according to temperature of a battery for an electric vehicle, and storing an allowable current map according to a control pilot (CP) duty; and

a temperature controller comparing a maximum charging current corresponding to a current temperature of the battery with an allowable current corresponding to a current CP duty to determine whether to increase the temperature of the battery,

wherein the temperature controller controls a temperature rising device to increase the temperature of the battery when the maximum charging current corresponding to the current temperature of the battery is lower than the allowable current corresponding to the current CP duty, and

wherein the temperature controller sets a target temperature of the temperature rising device to allow the maximum charging current corresponding to the current temperature of the battery to be the allowable current corresponding to the current CP duty when increasing the temperature of the battery.

2. The battery temperature control system according to claim 1 , wherein the temperature controller controls a temperature rising device to increase the temperature of the battery when a battery cell voltage is lower than a cut-off voltage and the maximum charging current corresponding to the current temperature of the battery is lower than the allowable current corresponding to the current CP duty.

3. The battery temperature control system according to claim 2 , wherein the temperature controller sets a target temperature of the temperature rising device to allow the maximum charging current corresponding to the current temperature of the battery to be the allowable current corresponding to the current CP duty when increasing the temperature of the battery.
