Hello everyone! This is Tianjin Enerbyte lithium battery channel. 

I am located next to a cold storage truck. Today I would like to share with you the test process of charging and heating Enerbyte lithium batteries in a subzero low temperature environment. Yesterday, we put the lithium batteries in and carried out cooling treatment. Currently nearly twenty four hours passing, we will go inside later to look at the changes in the temperature of the lithium battery.

I have come in, and the temperature inside the cold storage is really low. 

There are three lithium batteries undergoing cooling processing here. 

Now let's take a look at the real-time temperature of the battery.

Through the screen, we can see that the battery temperature has dropped to about below minus twenty degrees Celsius. 

At the same time, you can also see that the voltage difference of our cells is still very small, only twenty-one millivolts, which means our cells quality is very good and they still perform well in sub-zero low temperature environments.

It is now afternoon. We have driven the cold storage truck into the factory, and connected the battery with charger. It is ready to conduct charging and heating tests in sub-zero low temperature environments. 

Behind me are two technicians from our company, who are conducting testing and data recording on the battery before charging. After they complete the inspection, we will start the charging test.

Since the battery has been frozen for a day and night, you can see that the outer box of the battery has been frosted. 

I just communicated with the technician and learned that this is a heating solution specially customized for one of our customers. 

The battery has been charged for about thirty minutes and has already heated up by six degrees Celsius. The temperature rises very quickly. This solution is suitable for the low temperature environment that require a fast heating speed.

The above is our test sharing on the charging and heating process of low-temperature cold storage batteries. Our technicians will continue to test and record. If you would like to know more test results, or are interested in Enerbyte lithium batteries, please feel free to contact us.  

Thank you for watching. Bye bye!
