Title:
ESTIMATION DEVICE FOR ESTIMATING BATTERY CHARGE RATE
Document Type and Number:
Japanese Patent JP2023064864
Kind Code:
A
Abstract:
To provide a technique for estimating the charging rate of a battery with a simple configuration.SOLUTION: An estimation device for estimating a charging rate of a battery that supplies power to auxiliary equipment mounted on a vehicle, includes: a voltage sensor to detect battery voltage; a temperature sensor to detect battery temperature; and a processing circuit connected to the pressure sensor and the temperature sensor and performing an estimation process to estimate the charging rate of the battery. The estimation process is executed while the vehicle is parked, and estimates the charging rate of the battery based on a detected voltage detected by the voltage sensor and a detected voltage detected by the temperature sensor.SELECTED DRAWING: Figure 2
