What is the Purpose of Battery Testing?

A battery refers to a space in a cup, tank, or other composite container containing an electrolyte solution and metal electrodes that generate electric current, an apparatus that can convert chemical energy into electrical energy, and has a positive and negative pole. With the advancement of technology, batteries refer to small devices that can generate electricity, such as solar cells.

Classification of battery testing methods:

In order to ensure the safe use of lithium-ion batteries, international organizations have developed corresponding safety testing standards for various lithium-ion batteries. The general testing standards for battery testing usually divide safety testing items into the following four categories:

  • Electrical testing: overcharging, overdischarging, external short circuit, forced discharge, etc.

  • Mechanical testing: compression, puncture, impact, vibration, falling, etc.

  • Thermal testing: high and low temperature cycling, combustion, microwave heating, etc.

  • Environmental simulation: high altitude low pressure simulation, salt spray test, etc.

Characteristics of parameters: The main performance parameters of batteries are electromotive force, capacity, specific energy, and resistance. Using batteries as a source of energy, stable voltage, stable current, long-term stable power supply, and small external influences on current can be obtained. The battery structure is simple and easy to carry, and the charging and discharging is easy and feasible. It is not affected by external climate and temperature, and its performance is stable and reliable, playing a great role in various aspects of modern social life.

The purpose of battery testing:

Currently, without a doubt, batteries are the most important and critical part of electric vehicles. Batteries determine the performance and endurance of vehicles, as well as lifespan and safety. Therefore, both vehicle manufacturers and battery manufacturers need to conduct comprehensive battery testing in order to truly understand batteries and use them properly.

Understanding the characteristics of batteries:

We need to use battery testing to understand important parameters such as battery capacity, internal resistance, voltage characteristics, rate characteristics, temperature characteristics, cycle life, energy density, etc. These parameters are needed to demonstrate whether the tested battery has achieved the original design goal, and also to achieve better management and control during the use of batteries through these parameters.

Evaluating the battery's ability to meet needs:

This type of battery testing can be understood as starting from the application requirements, deducing the characteristics that the battery should meet, and testing whether the tested battery meets the standard. For example, vehicle manufacturers will design battery cold start testing based on the low temperature driving scenario, design energy efficiency testing based on power consumption indicators, and design power performance testing based on vehicle climbing or acceleration scenarios. In addition, tests such as overcharging, overdischarging, short circuit, overtemperature, compression and puncture are designed from the perspective of vehicle safety.
