Battery production is complex engineering, every point should be controlled strictly

The recent pure electric vehicle fire incident has made the battery safety of pure electric vehicles a hot topic. At present, most of the power batteries used in domestic pure electric vehicles are lithium-ion batteries,best lithium ion battery machine company which are often referred to as lithium batteries. So how about the technology and safety of lithium batteries?

Lithium batteries themselves can be safe, and in the manufacturing process, they are prone to safety hazards.

Lithium batteries catch fire mainly because of the short circuit of the battery.equipment for lithium battery assembly In the manufacture of lithium-ion batteries, screws are used to connect the cells to the cells in the battery pack. Loose screws increase resistance, which can lead to overheating and fire. For example, some battery manufacturers use laser welding to connect, welding slag may fall between the two batteries, when the car collision or road bumps, etc., the welding slag inside the battery pack can also cause the battery short-circuit, causing a fire.

At present, China's lithium battery technology level in the world can reach a comprehensive first level, China's battery companies have entered most of the world's leading automotive companies. Battery is not only in the industrial scale is located in the world's leading, in terms of innovation and research is also on a par with foreign countries. With the improvement of manufacturing level, the risk of battery fire will be lower and lower. High-quality manufacturing is therefore a top priority.

Emphasis on safety technology, promote the use of batteries can be used before the occurrence of safety accidents early warning management function

In safety technology, China is currently studying the battery before the accident early warning, although not 100% perfect, but most of the early warning function has been realized, and some safety technology has been used in the enterprise. Through better production materials to make the battery more reliable, in the event of a problem after the heat generated by the reduction, and in the event of a battery problem after the module transfer process to pass the other battery chances of reducing the battery fire, so that the battery will not burn the whole car is our goal. Currently has been promoted to enterprises.

Currently lithium batteries have a long range and are not economical for urban transportation.

Consumers are generally concerned about range and battery life, for lithium batteries, the longer the range of the vehicle itself uses more batteries, increase the weight but more power consumption; for battery life, the battery industry will become more and more mature, the level of manufacturing will also be more and more high, like scientific research to find the reasons and overcome, the next few years the battery life will be up to 10-15 years.
