AI Technical Summary

Technical Problem

In vehicles equipped with multiple replaceable batteries, achieving an appropriate weight balance when the number of mounted batteries is less than the upper limit can be challenging due to improper positioning.

Method used

A control device determines the mounting positions of power storage devices by considering the relationship between the vehicle's center position and the drive source, ensuring that the center is sandwiched between the drive source positions, particularly for two-wheel and four-wheel drive vehicles.

Benefits of technology

This approach maintains an appropriate vehicle weight balance by strategically positioning batteries, preventing bias towards the drive source side and ensuring balanced distribution.

Abstract

To obtain weight balance of a vehicle which is appropriate when less than an upper limit number of batteries are mounted thereon.SOLUTION: An ECU executes a process which includes: a step (S104) of setting all mountable positions as mounting positions, when it is determined that battery replacement is executed (YES in S100) and when the number of battery packs is equal to an upper limit number after the replacement is executed (YES in S102); a step (S108) in which when the number of the battery packs is less than the upper limit number (NO in S102) and when the battery packs are mounted on a two-wheel-drive vehicle (YES in S106), the mountable position located across a center of the vehicle with respect to a driving source is determined as the mounting position; and a step (S110) in which when the battery packs are mounted on a four-wheel-drive vehicle (NO in S106), the mountable position close to the center of the vehicle is determined as the mounting position.SELECTED DRAWING: Figure 4
