Title:

電流積算装置

Document Type and Number:

Japanese Patent JP5924135

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To accurately calculate an integrate value of the battery current without bringing the cost increase.SOLUTION: A current integration device of a vehicle that includes: an electric motor 1 to operate to assist torque to an internal combustion engine; a first battery 3 to supply electric power to the first electric motor 1 during execution of torque assist; a second battery 4 to supply electric power to an electric load 10 other than the electric motor 1 during execution of torque assist; and a relay 5 that connects the first battery 3 and the second battery 4 in parallel during non-execution of torque assist and releases the parallel connection during execution of the torque assist, includes: a current detection means 7 to detect charge/discharge current of the first battery 3; a current integration value calculation means 6 to calculate the current integration value of the first battery 3 by integration of the detection value of the current detection means 7; and a current value correction means 6 that memorizes the current value that flows during the torque assist execution exceeding the measurable range of a current detecting means 7 as a current value for correction beforehand and based on the memorized value, corrects the current integration value.
