Abstract Lithium-ion (Li-ion) batteries have recently become the main source of power in portable devices due to advantages such as high energy density. However, Li-ion cells operate well only in a specific temperature range. Degraded preperformance is a consequence of low temperature operation, and potential fire risk originates from thermal runaway at elevated temperatures. Efficient thermal management of Li-ion cells and battery packs is essential to ensure safe and durable performance in wide temperature range. Thermoelectric coolers (TECs), which have been used widely for electronics cooling may also be appropriate for battery cooling due to size compactness, working with direct current. This paper presents experimental characterization of cooling of a prismatic test cell with TECs on two sides. Cooling effect of TEC on the cell core and surface temperatures is investigated at different TEC power rates. Results show core and surface temperatures of the test cell decrease significantly. The obtained results show that by applying the TEC, a temperature drop of 10 °C was achieved for 0.75A TEC current. The optimum TEC current can be selected based on the application. In addition, numerical simulations are carried out to compare with experimental measurements. Heating effect of mounted TECs can be easily achieved just by changing current direction. Experimental results reveal TECs can heat up a cell in cold climate shortly. In addition, thermo electric module may also offer insulating effect in cold climate. Results presented in this paper illustrate potential application of thermoelectric cooling for thermal management of Li-ion cells.

The Impact

Pulsed thermoelectric cooling is an attractive approach for the site specific thermal management of infrared sensors and other low-heat flux devices. Intense Joule heating caused by electrical interface resistance, however, can severely degrade pulsed cooling performance. Numerical simulations are used to quantify the impact of the interface resistance on pulsed thermoelectric cooling. The degradation in performance is most pronounced for microcoolers that have small bulk resistivity at high pulse amplitudes. Our work also forms a basis for new techniques to probe interfaces in TE devices for energy harvesting as well as cooling applications.

The isothermal displacement calorimeter described previously has been modified by the inclusion of a thermoelectric cooling module to allow the study of both endothermic and exothermic mixing. Other modifications are also described. Excess enthalpies are reported for 1,4-dioxan+tetrachloro-methane, benzene+dichloromethane, tetrahydrofuran+water, and ethanol+water at 298.15 K and 1,4- dioxan+dichloromethane at 298.15 and 303.15 K. These mixtures have been suggested as possible reference mixtures for either checking the operation of, or calibrating, calorimeters to be used for making measurements on exothermic mixtures. The performances of our calorimeters have been evaluated on the basis of the results presented here and by comparison with previous results. Some advantages and disadvantages of the proposed reference mixtures are discussed. Photochemical effects from the tungsten thermostat lamp affect the results for mixtures of tetra-chloromethane with 1,4-dioxan.

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 Module

A thermoelectric cooling system supplied by photovoltaic solar energy was built and evaluated with different thermal loads. The thermoelectric cooling module consumes 70 W, it is supplied by a photovoltaic system of 90 W and 40 Ah battery. The voltage and electrical current in each component (panels, battery, and electric charge) has been measured. The tests were performed with different thermal loads placed in glass containers used for vaccines. To analyze the cooling and preservation process, the experiments were started at room temperature. The results show that the thermoelectric cooling system works for small thermal loads, and it could be applied to transport vaccines in isolated areas where people carry medicines in small containers that do not maintain the temperature necessary for the conservation of vaccines.
