The need for battery testing services

need for battery testing

Lithium-ion batteries are an integral part of every electronic gadget. The need for battery testing is undeniable because all businesses require optimal batteries that can power up their devices, whether they are cell phones, remote controls, video games or laptops.

Every tool undergoes rigorous testing in its production phase to ensure maximum quality and stability. The Lithium-ion batteries also need to be subjected to a testing phase to provide a decent and safe customer experience.

Need for Battery Testing Services

In 2016, a popular smartphone company had to call back all the units of a particular model because the batteries of that model were exploding reportedly. Such incidents can cause loss of trust in the customer’s mind. It’s a known fact that the battery is the only part inside a smartphone, tablet, wireless earphones, etc., that is prone to explosion. An explosion in a battery can not only affect the person holding the phone but the nearby people too.

Other battery issues like a short life span, quickly losing charge, extensive rise in the temperature, and slow charging can also affect the consumers. These cases are not hazardous. Still, they can bring a sense of dissatisfaction into the customer’s mind. It might even happen that the customer would choose some other company over yours.

It can be concluded that battery testing is vital for any company because it is more prone to failures than other components. 

Battery testing services can help ensure the efficiency of your batteries. Let us look at each step followed by a battery testing service to ensure the batteries’ stability and best performance for the end user.

1.) Capacity Test

The capacity test is one of the essential tests for maintaining the quality and rating of the battery.

This test is done by applying a constant load of current, equal to the battery’s Ampere-Hour rating. While the load is put, the voltage of the battery and voltage of each cell is monitored.

The battery passes this test if the given cell’s voltage remains more than or equal to the specified limit. Some difficulties arrive while testing this, like time lag, reading error, etc.

There are chances of error in correctness of the measurements in this process, and this is why it is best to select a professional battery testing service provider for this. Also, there can be a mistake in taking readings if the production in a large scale, leading to further errors.

It can be crucial to get the batteries tested by an automated machine handled by professionals, before rolling them out. A simple voltmeter test can never give an accurate rating.

2.) Charge Acceptance Test

A battery needs to accept the charge. A Lithium-ion battery is expected to run for multiple cycles.

The charge acceptance test is carried out by applying a constant current charge for a defined period. The voltage of each cell must also be measured by the time the charge cycle continues. The charging is done for 10-30 minutes more than the specified theoretical time. This is done because the process of charging is rarely 100% efficient. Thus, to ensure the most precise reading, overcharging is performed on the battery.

It is essential to keep a check on the battery’s temperature while it is charging. If there is a significant temperature change (more than 5-degree Celsius), it signifies a battery issue, like a cell separator failure. In those cases, the battery needs to be replaced as this failure is irreparable.

Additionally, there is a possibility of many wrong readings due to error and time difference, and it is best to choose a battery testing service to do this.

3.) Final Analysis

Each reading is taken into account (online or offline). This data is then visualized and analyzed by experts or automated computers. A significant deviation from the mean values indicates that there is some problem with the battery. A computer must perform this as it comprises a lot of data for calculation and analysis. The more the data, the higher is the scope of human error.

Testing of batteries is essential from the point of view of the safety of consumers. It can be found from the facts mentioned above that testing of batteries can produce the best results only if done with an automated system under the supervision of an expert. The data achieved while testing can also be used for improvising automated algorithms for enhancing the battery testing procedures. Battery testing services play a crucial role in preserving the quality, standard, and safety of the lithium-ion batteries used across various industries.
