The invention relates to a vehicle storage battery aging identification method and device, a vehicle and a storage medium, when the vehicle enters a dormant state, voltage information of a storage battery and a first moment when the vehicle enters the dormant state are obtained, and then a charging instruction for the storage battery is triggered in response to the vehicle in the dormant state; and determining an interval duration between a second moment corresponding to the charging instruction and the first moment, and finally determining an aging identification result of the storage battery according to the interval duration and a reference interval duration corresponding to the voltage information. According to the technical scheme, in the aging detection process of the vehicle storage battery, no extra sensor needs to be added, and therefore the aging detection cost of the storage battery can be reduced.
