Introduction to Electromotive Force. Voltage has many sources, a few of which are shown in Figure (PageIndex{2}). All such devices create a potential difference and can supply current if connected to a circuit. A special type of potential difference is known as electromotive force (emf).The emf is not a force at all, but the term ''electromotive force'' is used for historical reasons.
In this paper, a heating strategy using high-frequency alternating current (AC) is proposed to internally heat lithium-ion batteries (LIB) at low temperatures.
The lithium-ion batteries (LIB), in comparison with alkaline and lead-acid batteries, have a high specific energy density, long service life and high charging speed. These qualities are inherent in LIB under normal operating conditions at a positive temperature. However, at low temperatures, the operation of LIB without heating leads to almost complete loss of all its positive properties

To control the heating power of the battery pack and enhance energy efficiency, a Proportional Integration Differentiation (PID) algorithm was implemented to restrict the power of the DC/DC converter.
The strategy aims to strike a good balance between rapid heating of the battery at low temperatures and minimizing damage to the battery’s lifespan without the need for an additional power source.
The inlet temperature, heating time, and external ambient temperature of the battery heating system all have an effect on the heat balance performance. The temperature uniformity is poor due to the narrow space, and the temperature of the water heating the battery is also decreased with the increase of the distance the water flows through .
The paper proposes a power battery low-temperature AC preheating circuit to enhance battery performance at low temperatures. The heating device is used in the LIB pack of the electric vehicle. Figure 1 shows that the LIB pack consists of four modules; each module is divided into AB batteries.
The proposed pulse heating method could make full use of the internal resistance of the battery for heating and theoretically reduce the impact on the battery life via rapid reverse depolarization. Qu et al. proposed a pulse self-heating strategy by designing their own circuit to achieve fast and safe heating of LIB at low temperatures.
The proposed heating strategy and frequency have been proven to be harmless to the health of the battery. The AC heating method of the power battery can improve the battery performance, such as charging and discharging efficiency, and realize rapid heating, so it has important application value. The authors declare no competing financial interest.
The operating process involves the liquid (e.g., silicone oil) heated by the heater flows between the cells by employing the pump, facilitating the transfer of heat from the liquid to the battery. The inlet temperature, heating time, and external ambient temperature of the battery heating system all have an effect on the heat balance performance.
