AI Technical Summary

Technical Problem

During external charging of a vehicle's power storage device, the input power can exceed the allowable input power due to response delays in the charger, especially when the power consumption of the electric compressor decreases.

Method used

The vehicle employs a control device that transmits a power level lower than the sum of the energy storage device's allowable input power and the electric compressor's power consumption, with a margin, to prevent input power from exceeding the limit, and adjusts this margin based on the charger's response delay.

Benefits of technology

This approach prevents the input power of the energy storage device from exceeding the allowable input power by accounting for response delays, effectively managing power transmission during external charging.

Abstract

To prevent the input power of a power storage device from exceeding an allowable input power during external charging.SOLUTION: A vehicle includes: a power storage device; a cooling device that cools the power storage device by driving an electric compressor connected to a power line together with the power storage device; and a control device that transmits requested power to an external power supply device during external charging of charging the power storage device via the power line using power from the external power supply device outside the vehicle. During operation of the cooling device during the external charging, the control device transmits, to the external power supply device, requested power that is lower by a margin than the sum of the allowable input power of the power storage device and the power consumption of the electric compressor.SELECTED DRAWING: Figure 3
