With the development and popularization of electric vehicles, electric heavy truck, as an environmentally friendly and efficient means of transportation, has attracted more and more attention and applications. As an important part of the electric heavy truck, the performance and quality of the battery directly affect the mileage, power output and safety of the vehicle. This article will discuss the battery requirements of electric heavy truck, and analyze and introduce them from the aspects of endurance, power output, safety and environmental protection.

I. Endurance

1. high energy density: electric heavy truck pair battery the primary requirement is to have high energy density and be able to store more electric energy in a limited space to achieve longer endurance mileage.
2. Long cycle life: electric heavy truck needs to carry out long-distance transportation frequently, so the battery needs to have a long cycle life and can withstand multiple deep charge and discharge cycles without damage.

II. Power output

1. high power density: The electric heavy truck needs to have high power output, and the battery needs to have high power density, which can provide enough power output to meet the needs of vehicle acceleration and climbing.
2. Fast charging: in order to improve the operation efficiency, the battery needs to support fast charging, which can be fully charged in a short time, reduce the charging time and improve the utilization rate of the vehicle.

III. Security

1. high temperature tolerance: during operation, the electric heavy truck battery is vulnerable to high temperature, and it needs to have good high temperature tolerance to avoid safety accidents caused by overheating.
2. Short circuit protection: the battery needs to have the function of short circuit protection. In case of short circuit, the circuit can be cut off in time to avoid safety accidents.

IV. Environmental Protection

1. recyclable: the requirements of the electric heavy truck on the battery also include high recyclable utilization rate, reducing the waste of resources and reducing the impact on the environment.
2. Low Pollution: in the process of production, use and scrapping, batteries should minimize the pollution to the environment, meet the requirements of environmental protection, and promote the development of green transportation.

Electric heavy truck has high requirements for batteries, including high energy density, high power density, long cycle life, safety and environmental protection. Only batteries that meet these requirements can ensure the normal operation and sustainable development of electric heavy trucks.
