Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of International Application No. PCT/CN2024/082504, filed on Mar. 19, 2024, which claims priority to Chinese Patent Application No. 202310807980.5, filed on Jul. 3, 2023. The disclosures of the aforementioned applications are hereby incorporated by reference in their entireties. TECHNICAL FIELD The embodiments relate to the field of energy technologies, and to a multi-way valve, a heat management apparatus, an energy storage device, and a vehicle. BACKGROUND With continuous development and application of new energy vehicles and energy storage technologies, a quantity and complexity of pipelines in a heat management apparatus have also improved significantly. For example, a new energy vehicle is used as an example. The vehicle may include a battery pack, a motor, a heat management apparatus, and the like. The battery pack may supply electric energy to the motor, and the motor in operation may drive a wheel to rotate, to implement a traveling function of the vehicle. The heat management apparatus may cool or heat the battery pack and the motor, so that the battery pack and the motor are in normal temperature ranges. In addition, the heat management apparatus may further effectively adjust and control a temperature of a passenger compartment, to meet a cooling or heat supply requirement of a user. In actual application, the heat management apparatus may effectively adjust and control heat of the battery pack, the motor, and the passenger compartment by using a pipeline. The pipeline is equipped with a multi-way valve. The multi-way valve may adjust a flow path of a cooling medium in the pipeline, thereby implementing flexible adjustment and control. However, the current multi-way valve has problems such as a complex structure and an unreasonable design. This is not conducive to implementing a miniaturization design. SUMMARY The embodiments provide a multi-way valve that has a simple structure and is conducive to implementing a miniaturization design, a heat management apparatus, an energy storage device, and a vehicle. According to a first aspect, the embodiments provide a multi-way valve, which may include a housing, at least two valve cores, a transmission assembly, and a driver assembly. The housing is configured to accommodate the at least two valve cores. For the at least two valve cores, each valve core is configured to rotate relative to the housing. The at least two valve cores are sequentially disposed in an axial direction. The driver assembly is disposed on an outer side of the housing. The driver assembly is configured to drive, by using the transmission assembly, each valve core to rotate. In the multi-way valve provided in the embodiments, there is a flow channel in each valve core, so that a quantity of flow channels in the multi-way valve and a quantity of interfaces in the housing can be effectively increased. In addition, the plurality of valve cores are sequentially disposed in the axial direction, and no radial size of the multi-way valve is additionally increased. Therefore, this facilitates a miniaturization design of the multi-way valve. In addition, the interface in the housing may be distributed in the axial direction. Therefore, more interfaces with larger diameters can be disposed on a limited outer circumferential surface, to help ensure a flow rate of the multi-way valve. The driver assembly may drive, by using the transmission assembly, each valve core to rotate, so that mutual interference between different valve cores can be avoided. Therefore, when a connection state or a disconnection state between different interfaces needs to be switched, flexibility and reliability are good. In an example, the at least two valve cores may include a first valve core and a second valve core. The driver assembly may include a first driver and a second driver. The transmission assembly may include a first shaft body and a second shaft body. A shaft center of the first shaft body coincides with a shaft center of the second shaft body. The first shaft body is connected to the first driver and the first valve core, so that the first driver can drive, by using the first shaft body, the first valve core to rotate. The second shaft body is connected to the second driver and the second valve core, so that the second driver can drive, by using the second shaft body, the second valve core to rotate. In summary, the first driver and the second driver may drive, by using two different shaft bodies, the first valve core and the second valve core to rotate respectively. During specific disposition, the first shaft body may have a first end connected to the first driver. The second shaft body may have a second end connected to the second driver. The first end of the first shaft body and the second end of the second shaft body are sequentially disposed in the axial direction, so that both the first shaft body and the second shaft body
