Introduction
节能汽车The 863 Program is a major project launched by the Chinese government in the new energy and energy conservation industries.In 2023, the 863 program launched a major proj
ect to standardize the performance testing of lithium ion power batteries used in electric vehicles.This paper studies the test standards of lithium ion batteries used in electric vehicles in the 863 program in 2023.This paper focuses on analyzing the test methods, test parameters, requirements, standard characteristics and precautions of battery performance.
Test Parameters and Methods
1. Capacity tests: The capacity test measures the capacity of the battery at a specified temperature.The temperature range of the battery is determined by the manufacturer and the test temperature is generally 20±5℃.The discharge current is determined by the manufacturer.The battery needs to be charged and discharged according to the specified conditions, and the capacity is measured.
2. Discharge characteristic tests: The discharge characteristic tests measure the discharge characteristics of the batteries, such as discharge current, discharge voltage and remaining capacity in different temperatures and environments.Discharge tests are u
sually conducted in the temperature range of 20~50℃.
