How to evaluate traction battery performance?

In order to control the production cost and product quality accurately, the accurate evaluation of traction battery performance has received extensive attention around the industry. The basic parameters of a battery include performance parameters, safety parameters, durability parameters, accompany with cost, environmental protection and so on.

What is the core evaluation index of battery life?

For the real vehicle application, the core evaluation index of battery life is still capacity energy, internal resistance power, heat generation and consistency. But in these parameters, the main factors to consider are the rate of change and the threshold value of the boundary.

Is there a clear guidance for battery manufacturers?

Henceforth, it can be said that despite the government and associated standards and regulations developing bodies being aware of the situation of confusion among the battery manufacturers along with the concept of increment in the cost linked with the number of test samples, there is no clear guidance for the manufacturers available.

Where can I find a manual for battery durability assessment?

The United States Department of Energy (DoE): DoE mainly deals with the development of manuals for battery durability assessment. A list of manuals and their detailed description can be found in the technical report prepared by the Joint Research Centre (JRC) .

What are battery testing standards & regulations?

There are numerous battery testing standards and regulations in the market that helps the manufacturer to design the battery system and introduce them in the market. The testing methods described in these standards and regulations help in accessing the performance and safety of the battery system but are not always pertinent.

What is a battery performance test system?

At the cell level, the battery performance test system mainly includes the following aspects. The first is the consistency among diferent cells, including the consistency of weight, open circuit voltage, internal resistance, and capacity.
