Electric Vehicle requirements for batteries

The power source of Electric Sightseeing Car is its battery. In order to increase the driving distance of Electric Sightseeing Car, the capacity of the battery must be large enough. However, increasing the capacity of the battery, as the volume of the battery pack increases, its mass also increases, which will affect the power of the vehicle and the overall vehicle layout. Therefore, Electric Vehicle need to be based on the design goals of Electric Vehicle, the optional battery and road driving conditions. The specific requirements are summarized as follows.

1. The battery capacity must be large enough to meet the design goals of the electric vehicle's driving range. In addition, the capacity and energy of the battery should ensure that the car is in a specific working state. Power capacity.

2. The battery can achieve deep discharge without affecting its life. It is required that the battery of an electric vehicle can work at full load and achieve full discharge when necessary.

3. The specific energy and energy density of the battery should be as large as possible to reduce the structural size of the battery pack, reduce the mass of the battery pack and promote the overall structural design of the vehicle to ensure the power and passenger space of the electric vehicle.

4. The acceptable charging current of the battery should be large. For Electric Sightseeing Car with a braking energy feedback system, it is also required that the battery's acceptable charging current be large, and the time can be short. It can accept pulse current charging up to 5C, which helps to improve the efficiency of the vehicle's braking energy recovery.
