The present invention addresses the problem of suppressing deterioration of a single cell due to rapid charging. The invention relates to a charging system and a vehicle. The battery system is a system for charging a battery, and is provided with a battery and a processor. The processor accumulates the total amount of charge to the battery at the time of rapid charging (step S114), and restricts rapid charging to the battery when the total amount of charge is equal to or greater than a threshold value (steps S115, S116).

Therefore, lithium deposition can be suppressed. As a result, it is possible to suppress deterioration of the cell due to rapid charging.
