The invention relates to a battery electric quantity equalization circuit, a heating circuit, a method, a device and a vehicle. The battery electric quantity equalization circuit comprises a resonance assembly, a first battery pack and a second battery pack, the first battery pack and the second battery pack are communicated through a resonance assembly; the resonance assembly is used for transferring electric quantity between the first battery pack and the second battery pack based on the resonance effect, so that the electric quantity of the first battery pack is equal to that of the second battery pack. Based on the circuit, electric quantity equalization between the first battery pack and the second battery pack can be realized, and compared with a scheme of consuming the electric quantity of a battery with relatively high electric quantity through a resistor in the prior art, the electric quantity is only transferred instead of being directly consumed, so that the aim of electric quantity equalization is fulfilled; therefore, electricity consumption in the electricity balancing process can be reduced, and the electric energy utilization rate is improved.
本公开涉及一种电池电量均衡电路、加热电路、方法、装置及车辆。该电池电量均衡电路包括:谐振组件、第一电池组和第二电池组;第一电池组和第二电池组之间通过谐振组件连通;谐振组件用于基于谐振效应进行第一电池组和第二电池组之间的电量转移,以使第一电池组和第二电池组的电量相等。基于上述电路,本公开可以实现第一电池组和第二电池组之间的电量均衡,相比于现有技术中的通过电阻消耗电量较高的电池的电量的方案,本公开仅仅是对电量进行转移,而并非直接通过消耗电能的途径以达到电量均衡的目的,因此可以减小均衡电量过程中的电量消耗,提高电能利用率。
