Background

Electric vehicles, i.e. electrically driven vehicles, are also known as electrically driven vehicles. Electric vehicles are classified into ac electric vehicles and dc electric vehicles. In general, an electric vehicle uses a battery as an energy source, and converts electric energy into mechanical energy to move through a controller, a motor and other components, so as to control the current magnitude and change the speed.

There are two common battery mounting positions of electric vehicles on the market, one is to mount the battery below the cushion, the other is to mount in the pedal inner groove of the electric vehicle, and the battery mounted in the pedal of the electric vehicle is closer to the ground, in order to prevent water accumulation in the pedal inner groove of the electric vehicle from splashing, a water permeable opening is usually formed at the bottom plate of the pedal inner groove, however, the battery in the pedal groove is not provided with a waterproof device, which results in that when the electric vehicle rides in water, water is easy to splash into the pedal from the water permeable opening, even if water can flow out from the water permeable opening, but the battery still contacts the battery first, so that the water of the battery is damaged. Accordingly, a battery protection case is provided by those skilled in the art to solve the problems set forth in the background art.
