[0002] With the rapid development of electric boat technology, batteries, as the core power source, have become a key factor affecting their performance and lifespan. Existing battery temperature control systems are mostly limited to cooling or heating the battery surface, or the cabin mostly controls the indoor temperature through ventilation equipment such as air conditioners to control the battery temperature, which fails to effectively solve the problem of controlling the overall temperature in the battery compartment. Therefore, designing a system that can efficiently and evenly control the temperature of the battery compartment has important practical significance and application prospects. The existing technology either uses ventilation equipment to control the temperature or uses a thermostat, which results in uneven temperature control and is relatively energy-consuming. In addition, the temperature control methods are different in hot weather and cold weather, resulting in a more complex temperature control structure.

This technology does not involve the technical solution of the present application. Utility Model Content
