What is a battery thermal management system with direct liquid cooling?

Zhoujian et al. studied a battery thermal management system with direct liquid cooling using NOVEC 7000 coolant. The proposed cooling system provides outstanding thermal management efficiency for battery, with further maximum temperature of the battery’s surface, reducing as the flow rate of coolant increases.

What is a battery thermal management system?

An efficient battery thermal management system can prevent electrolyte freezing, lithium plating, and thermal runaways, helping to provide favorable operating conditions for Li-ion batteries . The commercially employed battery thermal management system includes air cooling and indirect liquid cooling as conventional cooling strategies.

Does lithium-ion battery thermal management use liquid-cooled BTMS?

Liquid cooling, due to its high thermal conductivity, is widely used in battery thermal management systems. This paper first introduces thermal management of lithium-ion batteries and liquid-cooled BTMS.

Which cooling media is used in battery thermal management systems?

The common cooling media in battery thermal management systems (BTMSs) are air, liquid, and phase change material (PCM) [ 22, 23 ]. Air cooling thermal management systems have advantages such as reliability as well as simplicity [ 24 ], but due to the low thermal conductivity of air, the amount of heat it can consume is limited [ 25 ].

Can direct liquid cooling improve battery thermal management in EVs?

However, extensive research still needs to be executed to commercialize direct liquid cooling as an advanced battery thermal management technique in EVs. The present review would be referred to as one that gives concrete direction in the search for a suitable advanced cooling strategy for battery thermal management in the next generation of EVs.

What is liquid cooling in lithium ion battery?

With the increasing application of the lithium-ion battery, higher requirements are put forward for battery thermal management systems. Compared with other cooling methods, liquid cooling is an efficient cooling method, which can control the maximum temperature and maximum temperature difference of the battery within an acceptable range.
