6 FAQs about [Principle of new energy battery temperature acquisition board]

What is the thermal behavior of a battery system?

Fig. 1 is a simplified illustration of a battery system's thermal behavior. The total heat output in a battery is from many different processes, including the intercalation and deintercalation of the existing ions (i.e., entropic heating), the heat of phase transition, overpotentials, and the heat discharge due to mixing.

Why do Li batteries need thermal management?

Due to the significant heat generation that li-batteries produce while they are operating, the temperature difference inside the battery module rises. This reduces the operating safety of battery and limits its life. Therefore, maintaining safe battery temperatures requires efficient thermal management using both active and passive.

How does high voltage affect battery thermal management system?

High voltage and increasing temperature will deteriorate the output performance of the existing battery thermal management system, and thus risk for loss of energy, damage to battery life, and low storage capacity is always there.

What is power battery thermal management technology?

In order to ensure the safety of electric vehicles in high and low temperature environments, improve the performance of electric vehicles and the service life of power battery packs, power battery thermal management technology has been widely emphasized by major automobile companies.

Does battery thermal management system use phase change materials?

Thermal optimization may be achieved battery thermal management system (BTMS) that employs phase change materials (PCMs). However, PCM's shortcomings in secondary heat dissipation and restricted thermal conductivity still require development in the design, structure, and materials used in BTMS.

Why do we need thermal management systems of batteries?

Thermal management systems of batteries must be sufficient to control energy loss, reduce carbon emission, and be capable of long-run heat and thermal energy storage and to help in gaining a longer battery life. Compared to metal oxide nanoparticles, CNTs are quite pricey despite their efficacy in improving the PCM's thermal properties.
