Water/Nanofluid Pulsating Flow in Thermoelectric Module for Cooling Electric Vehicle Battery Systems

Abstract

We investigated the results of the cooling performance of the pulsating water/nanofluids flowing in the thermoelectric cooling module for cooling electric vehicle battery systems. The experimental system was designed and constructed to consider the effects of the water block configuration, hot and cold side flow rates, supplied power input, and coolant types on the cooling performance of the thermoelectric module. The measured results from the present study with the Peltier module are verified against those without the thermoelectric module. Before entering the electric vehicle battering system with a Peltier module, the inlet coolant temperatures were 2.5-3.5℃ lower than those without the thermoelectric system. On the hot side, the maximum COP of the thermoelectric cooling module was 1.10 and 1.30 for water and nanofluids as coolant, respectively. The results obtained from the present approach can be used to optimize the battery cooling technique to operate in an appropriate temperature range for getting higher energy storage, durability, lifecycles, and efficiency.

Cooling characteristics of a lithium‐ion battery module based on flat aluminum heat pipe by considering thermal radiation

“…The cooling mediums of BTMS include air, liquid, phase change material (PCM) and heat pipe 10,11 . Besides, other solutions are also effective for BTMS, such as nanofluid cooling, 12 thermoelectric air‐cooling, 13 thermoelectric ferrofluid cooling 14 and pulsating water/nanofluid flowing in thermoelectric cooling 15 . Air cooling is the most traditional heat dissipation method, which is widely used in BTMS of EVs, such as Zhidou, Toyota Prius, Nissan Leaf and BYD E6.…”

Experimental Study of a Direct Immersion Liquid Cooling of a Li-Ion Battery for Electric Vehicles Applications

“…However, for EVs applications, liquid cooling methods are more effective because of their high thermal capacity. This technology was applied with a single-phase or two-phase refrigerant [10,11], or using nano-fluids [12] that flows into a heat exchanger rounding the power module's cells. In this configuration a further thermal resistance is introduced by the heat exchanger.…”

“…Next, Almodfer et al [44] used the random vector to determine the efficiency of a solar-powered thermoelectric cooler. The most productive studies have been continuously done [45][46][47][48][49][50][51][52][53]. They apply the thermoelectric cooling module for many systems, including; cold-hot water dispensers [45,46], sensible air cool-warm fan [47], liquid cooler module [48], cooling CPU [49], electric generator [50], the cooling module with nanofluid as coolant [51], and cooling electrical vehicle battery module [52,53].…”
