“…Lithium-ion batteries, as the most used battery in automotive battery modules, have many advantages such as long service life, high energy density and low self-discharge rate (Yang W. et al, 2020). However, lithium-ion battery also has many disadvantages, such as their high temperature requirements, and research shows that the most suitable operating range for lithium-ion batteries is 20-40 °C, with a temperature difference of 5 °C or less (Pradeep and Venugopal, 2020;. Excessive temperature difference as well as too high or too low temperature will have a large impact on the battery performance, resulting in a reduction in battery capacity, performance and shortened service life and other bad changes, which can seriously cause thermal runaway of the battery (Al-Zareer et al, 2019).…”

As a key component of a pure electric vehicle, the battery in an overheated state will have a direct impact on battery life and vehicle safety. To promote battery heat dissipation, a novel cobweb-like type (C-type) channel cooling plate with asymmetric inlet and outlet is designed. The C-type channel cooling plate is numerically simulated in two coolant flow directions (Ifd and IIfd), using the computational fluid dynamics software STAR-CCM+, and compared to the conventional serpentine type (S-type) channel. Meanwhile, the effects of three structural parameters (channel diameter, spacing, and cooling plate thickness) on maximum temperature and temperature difference of the C-type cooling plate, and pressure drop are investigated. Based on this, the C-type channel is optimized by orthogonal test. The results show that the C-type with IIfd coolant flow direction has a better heat dissipation effect on the battery module than the C-type with Ifd and S-type under the same conditions, and the maximum temperature and temperature difference are respectively reduced by 0.2% and 17.8%, while the pressure drop is increased by 17.3%. In addition, increasing channel diameter can obtain good battery temperature distribution and smaller pressure drop, while the increase of cooling plate thickness and channel spacing has a greater effect on the battery temperature difference compared to the change of maximum temperature. Finally, the results of the orthogonal tests show that the cooling effect is best when the diameter of the cobweb-like channel cooling plate is 7 mm, the thickness of the cooling plate is 12 mm, and the channel spacing is 16 mm, and the maximum temperature and temperature difference are reduced by 0.7% and 6.8%, respectively, and the pressure drop is reduced by 37.6% compared to the initial cobweb-like channel scheme. This offers a fresh perspective on cooling plate channel design in liquid-cooled battery thermal management.

Along with intensive people activities in different places, the demand on transportation increases. For some dense road, motorcycle might be the better choice due to its ability to move flexibly. This may lead to massive use of motorcycle powered by fossil fuel engine. Beside causing severe air pollution, this also causes high fuel consumption. Electric motorcycle is expected to be the answer for both problems, since it does not cause air pollution and does not require fossil fuel to operate. However, this motorcycle solely depends on energy stored in battery that needs some time to recharge. This difficulty makes the good points of electric motorcycle unattractive. The development of battery with high capacity and requires shorter time to charge is still on process. Therefore, optimal battery energy use is another solution for this case. This may be assisted with instrumentation system that presents some useful information for the driver regarding real time system operating condition. This paper presents development of instrumentation system including data acquisition that employs a microcontroller of Arduino Mega. A number of sensors are employed in the system including magnet sensor, current and voltage sensors. The system is implemented in a motorcycle powered by 1000 W, 48/36 V DC motor energized by 17.5 Ah 48 V Lithium-Ion Battery. Some measured data are processed and presented in an LCD on the dashboard, including RPM, speed, torque, the distance travelled, the remaining battery capacity and the distance that may still be achieved. An automatic data logger of DS3231RTC is used for recording the data and it is saved in a SD Card Memory. For verification purpose, the displayed data are benchmarked with those measured with standard measurement devices. It was confirmed that the data presented by the instrumentation system is sufficiently accurate.
