Title:
電池制御装置
Document Type and Number:
Japanese Patent JP7119921
Kind Code:
B2
Abstract:
To improve calculation precision of SOC of a battery in a vehicle configured such that the battery is exchangeable.SOLUTION: An I/O port 203 includes at least one of first to third resistors when a battery 90 is exchanged with a battery 10. The first resistor is an internal resistor of the battery 10 measured while the battery 10 is being mounted on a vehicle 1. The second resistor is an internal resistor of the battery 10 measured when removing the battery 10 mounted on another vehicle. The third resistor is an internal resistor of the battery 10 collected from another vehicle in a state in which the battery 10 is being mounted on other vehicles 2 to 5. A CPU 201 corrects a resistance map MR based on a resistance change rate K between an internal resistor R1 of the battery 90 and an internal resistor R2 of the battery 10.SELECTED DRAWING: Figure 5
