[PDF Version]Battery self-heating technology has emerged as a promising approach to enhance the power supply capability of lithium-ion batteries at low temperatures. However, in existing studies, the design of the heater circuit and the heating algorithm are typically considered separately, which compromises the heating performance.
In this paper, an optimal self-heating strategy is proposed for lithium-ion batteries with a pulse-width modulated self-heater. The heating current could be precisely controlled by the pulse width signal, without requiring any modifications to the electrical characteristics of the topology.
Particularly, the proposed self-heating strategy achieves real-time current adaptation and is easier to implement than other methods. Lithium-ion batteries (LiBs) have become the first choice for electric vehicles (EVs) and energy storage systems (ESSs) due to their high-power energy, long life cycle, and environmental friendliness .
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.
