“…In comparison, the standard CISPR 25 [33] regulates disturbances beginning from 150 kHz and up to 30 MHz. Also, for a cold battery, it is important to avoid heavy cyclings of the battery cells, since the internal impedance increases by a multiple [34]. Thus, the life time loss, due to the power dissipation is substantial as the temperature goes to 0 • C or below [35], [36].…”

In this paper, two types of filter capacitors of varying capacity, were connected to the battery packs of a cascaded H-Bridge single-star multilevel vehicle traction inverter, and their influence on the battery losses has been analyzed. The battery and capacitor simulation models used are experimentally verified in a down-scaled system. Different capacitor configurations were simulated for four drive cycle scenarios to determine the potentials for the mitigation of current pulse stresses and battery loss reduction with respect to the added weight. By adding capacitors corresponding to a weight of 4% of the initial battery storage, the peak current is reduced by 5%-20%, depending on the operating point from DC to a few kHz, and the battery losses are reduced by 10%. In comparison, it is demonstrated that adding supercapacitors is more beneficial for lower output frequencies, while adding electrolytic capacitors is better for higher output frequencies. Furthermore, the low-order voltage harmonics of the DC-rails between the converter and battery were reduced by 10%-30% for frequencies above 9 kHz, which decreases the potential of electromagnetic disturbances. In addition, during cold battery temperatures, when it is very important to avoid heavy cyclings, the loss reduction using the capacitors was 2.5 times larger than for nominal temperature.

“…[1][2] The actual operating conditions of electric vehicles are complex, and the temperature range is wide. The charge and discharge performance of lithium-ion batteries is directly related to the ambient temperature, [3][4][5] especially the low temperature, which has a greater impact on the battery charging and discharging performance. Some studies have shown that the capacity and operating voltage of the lithium-iron battery for electric vehicles at -10℃will be obviously reduced, and the performance will be deteriorated at -20℃.…”

In order to research on the low-temperature discharge performance of lithium-iron phosphate battery, the type 14500 and type 32650 batteries are selected as the research object, to test their low temperature discharge capacity and ohm internal resistance. The results indicate that the discharge capacity decreases as the temperature decreases, while the ohm internal resistance increases with the decrease of temperature, and the consistency between the battery monomer becomes worse. It is concluded tentatively that the influence of low-temperature on the discharge capacity of different types of batteries is different, the smaller the rated capacity, the smaller the discharge capacity ratio of the battery. The BP neural network model is established to take the normal temperature charging capacity, test temperature and ohm internal resistance as the input, discharge capacity as the output, and the error of the model is less than 8%, for the next step to achieve the battery at low-temperature discharge capacity of the online forecast to provide data support and theoretical basis.
