Title:
BATTERY MANAGEMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/053745
Kind Code:
A1
Abstract:
An energy manager (1), which functions as a battery management device, manages the state of a battery (B) for traveling mounted to a vehicle (A). The battery management device comprises a temperature adjustment unit (42), an environment information acquisition unit (10a), a temperature estimation unit (10b), a target temperature setting unit (10c), and a travel speed adjustment unit (10d). The target temperature setting unit sets a target battery temperature that allows the battery to be efficiently charged when the vehicle arrives at a charging facility through the traveling of the vehicle and the operation of the temperature adjustment unit. The travel speed adjustment unit uses a battery temperature estimated by the temperature estimation unit and the target battery temperature set by the target temperature setting unit to determine an adjustment amount of a travel speed at which the vehicle travels to the charging facility.
