Vehicle and vehicle battery replacing method

The invention provides a vehicle and a vehicle battery replacing method. The vehicle comprises N mounting spaces and M batteries, N is an odd number, M is smaller than N, and the mounting spaces are used for detachably mounting the batteries. The N mounting spaces are arranged in the first direction. The N mounting spaces comprise a first mounting space, and the first mounting space is located in the middle of the N mounting spaces in the first direction. And when M is an even number, the first mounting space is vacant, and the M batteries are equally distributed in the mounting spaces on the two sides of the first mounting space and are distributed symmetrically relative to the first mounting space. When M is an odd number, the first mounting space is used for mounting one of the M batteries, and the rest (M-1) batteries are equally distributed in the mounting spaces on the two sides of the first mounting space and are symmetrical about the first mounting space. According to the vehicle, the number of the batteries can be selected according to needs, the gravity center of the vehicle can be basically unchanged no matter how many the batteries are, and therefore the reliability of the vehicle can be improved.
