An optimal internal-heating strategy for lithium-ion batteries at low temperature considering both heating time and lifetime reduction. Appl. Energy. 256, 113797 (2019) Qu, Z.G., Jiang, Z.Y., Wang, Q.: Experimental study on pulse self–heating of lithium–ion battery at low temperature. Int. J. Heat Mass Transf. 135, 696–705 (2019)
The experimental results showed that the proposed battery self-heating strategy can heat a battery from about -20 to 5 °C in less than 600 s without having a large negative impact on battery health. This paper provides a guideline for further study that focuses on shortening the heating time before charging for LiBs at low temperatures.
For battery modules with relatively high demand for low-temperature heating, a single battery heating method can no longer meet the demand. Therefore, in recent years, most people have begun to study hybrid heating methods so that a battery can warm up rapidly while also improving temperature uniformity and safety.
The results show that the proposed battery heating strategy can heat the tested battery from about -20 °C to 0 °C in less than 5 minutes without a negative impact on battery health and the decreased current duration is beneficial to reducing the heating time.
The established high-frequency heating strategy is verified, and the impact of low-temperature (253.15 K) preheating of the battery as well as the thermal distribution of battery temperature, voltage, SOC, and current density on battery aging are discussed. The heating strategy’s correctness and effectiveness are confirmed. Figure 6.
