LG chemistry finds a method of solving Chevrolet Bolt EV battery issues

　　Author ：Iflowpower – Portable Power Station Supplier

Due to the fire problem caused by the battery in August, General Motor Company (GM) terminates the production of Chevrolet Boltev. Chemical cooperation with battery supplier LG, determine and resolve assembly errors that cause the vehicle battery to fire, General Motors have restored the production of Chevrolet Boltev and EUV models. General Motors acknowledging the deep cause of the fire in the battery is caused by manufacturing defects.

If the battery anode is broken during assembly, plus one of the battery diaphragms is also wrinkled therein, and the battery has a danger of fire. GREGLESS, Michigan University (UNIVENEWS ", speaking, speaking on the" DesignNews "interview:" Due to the production machine, there is a sign of cardians in a part of the production line, resulting in an anode break, and pleats in the diaphragm. "Gregless explanation:" This is obviously a problem that may happen, checking and maintaining production machine is particularly important.

"According to LES, the battery can accept one of the mistakes, but it cannot accept multiple errors. For example, the battery anode is broken or the battery diaphragm is wrinkled, and the battery does not cause a fire. If these two questions appear at the same time, perhaps it will cause fire.

However, in the modified assembly process, the "absolute" can be supplied, and the driver can believe that the problem of the battery has been discovered and solved. Now, LG battery factory in Michigan Holland and Hazelpark has resumed production. In fact, the battery plant has increased yield so that the supply of automotive battery modules that have been sold out for distributors.

Dougparks, Vice President of GM Global Product R & D, Purchasing and Supply Chain, said: "While we strive to advance the solution to the recall, we are grateful to the patient's customers and dealers. "Dougparks said:" Restoring battery production is just the first step, in the future, we will continue to work with LG active cooperation to get more battery supply. In addition, we believe that new advanced diagnostic software will supply more convenient for our customers.

According to GM, the software will be installed in Chevrolet dealers within 60 days, and new vehicle charging parameters will also explain the driver. This diagnostic software will be designed to detect specific exceptions, or can indicate battery damage by monitoring battery performance. The software will remind our customers any abnormal conditions and prioritize the replacement of corrupted battery modules.

The target is restored to 100% charging after the diagnosis is completed. The new battery will include extended battery for 8 years or 100,000 miles. The problem of LG batteries or generic automotive batteries should not be considered an electric car battery problem will inevitably.

On the contrary, every problem encountered during the development of lithium ion batteries will be inspected and repaired in the future. We have found a solution that will not happen in a similar situation. He pointed out that although the lithium ion battery has some leading development problems, these problems become less and less with battery technology.

We have not encountered a problem with a laptop battery for some time. This is a learning process. "my country's Chemistry and Physical Power Industry Association Yang Liu".
