AI Technical Summary
Technical Problem
In the existing technology, the charging control of electric vehicle batteries has failed to effectively balance the complexity of battery charging operations and battery degradation, resulting in cumbersome charging operations for users and shortened battery life.
Method used
A charging control device is used to calculate the rechargeable capacity and minimum SOC, and then charge the battery at a target SOC that is above the minimum SOC and suppresses battery degradation, or at a target charging capacity that is below the rechargeable capacity and suppresses battery degradation, thereby avoiding overcharging.
Benefits of technology
It effectively inhibits battery degradation, reduces charging frequency, simplifies user charging operations, and improves battery lifespan.

Abstract
The present application provides a charging control device, a mobile body, a charging control system, and a charging control method. In the charging control device, first, the chargeable amount is acquired. Next, the charging control device calculates the minimum SOC required for the vehicle to travel at a minimum limit after the next time. Next, the charging control device sets a target SOC that is above the minimum SOC and that suppresses battery deterioration. Alternatively, the charging control device sets a target charge amount that is below the chargeable amount and that suppresses battery deterioration. Accordingly, it is possible to eliminate the complexity of the charging operation of the battery while suppressing battery deterioration.
