Tianjin shares: How to realize the thermal management technology of high-energy lithium batteries?

On May 21st, the 11th Hi-Tech Lithium Industry Summit will be held in Shenzhen Four Seasons Hotel. At that time, Gangrou Peng, Vice President of Tianjin Research Institute, will deliver a wonderful speech focusing on the thermal management technology of high-energy lithium batteries.

At this stage, the cruising range of new energy vehicles and the energy density of power batteries have all been improved, and a series of challenges have emerged.

Gangrou Peng, deputy director of Tianjin Research Institute, said that with the increase of energy density, the heat generated by the power battery is also higher. Once the temperature rises, it will affect many working characteristics of the battery, such as SOC, charge and discharge efficiency, battery life, etc. In severe cases, it will lead to thermal runaway, affecting the safety and reliability of the vehicle system.

In order to ensure the safe operation of the battery, it is necessary to increase the heat dissipation requirement of the power battery and control the temperature of the battery pack within a reasonable range.

On May 21st, the 11th Hi-Tech Lithium Industry Summit will be held in Shenzhen Four Seasons Hotel. The 300+ segment of the heavyweight enterprise and 500+ enterprise executives will participate.

At that time, Gangrou Peng, the vice president of Tianjin Research Institute, will deliver a wonderful speech focusing on the thermal management technology of high-energy lithium batteries.

Gangrou Peng mentioned that it is very important to establish a sound thermal management design process. In addition, the use of simulation tools and new materials will also help the development and implementation of thermal management.

“Firstly, we need to establish a model analysis of the heat distribution of the power battery to obtain the temperature distribution. Secondly, we can optimize the battery size of the power battery through the model, etc. Finally, consider the specific heat dissipation scheme.” Gangrou Peng added, in general, for different battery packs, the countermeasures are also different.

All along, Tianjin has always controlled the temperature difference of the battery within 5 °C, adapting to a wide range of applications and ensuring the convenience of use.

It is understood that Tianjin shares as the champion of the three-dimensional soft pack battery installed capacity of logistics vehicles in 2017, has successfully entered the new energy passenger vehicle market, and has provided energy density of up to 145.9WH/KG for the national GM3 of Tongjia, Shaanxi ternary battery.

"This year, Tianjin will focus on exploring the new energy passenger vehicle market, mainly in the A0-class pure electric vehicles and A00-class micro-electric vehicles, as well as several long-range mid- to high-end passenger vehicles." Tianjin shares The relevant person in charge once revealed to Gaogong Lithium, it is expected that in the second half of the year, Tianjin will supply a large number of new energy passenger car companies in bulk.

What needs special mention is that this high-tech lithium battery industry summit will be based on the theme of “industry change, competing with safe-haven enterprises, stratification and stability”, in addition to Gangrou Peng’s wonderful speech, there will be several from the upstream and downstream of the industrial chain. Ten big coffees delivered a wonderful speech.

According to the staff of the summit organizing committee, as of May 5, the organizing committee has received more than 500 people to participate in the conference, and more than 80 well-known lithium-ion materials companies will attend the summit.
