Title:
BATTERY CELL TEMPERATURE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2019125562
Kind Code:
A
Abstract:
To provide a battery cell temperature control device capable of heating low temperature battery cells, in which a standby time till a stable output can be obtained from a battery can be reduced.SOLUTION: A battery cell temperature control device includes: a discharge resistor element Ba provided to each of a plurality of battery cells C1-Cn and generating heat by energization; temperature sensors T for obtaining temperatures of the respective battery cells C1-Cn; and a microcomputer M that energizes the discharge resistor elements Ba according to output values of the temperature sensors T. The microcomputer M calculates energizing periods, which bring the battery cells C1-Cn to a target temperature at a set time, to the discharge resistor elements Ba according to output values of the temperature sensors T.SELECTED DRAWING: Figure 1
