Designed as an independent and modular system, Guchen's 8kW battery thermal management system (BTMS) is specifically developed for power battery packs that require up to 8kW of cooling capacity. With adequate installation space, this adaptable unit can be applied to a wide range of new energy vehicles, including large buses and heavy-duty trucks.
Key Features:
- Modular Independence: Designed as a standalone unit for easy integration across different vehicle models.
- 8kW Cooling Capacity: Tailored to meet the cooling demands of power battery packs needing up to 8kW of cooling.
- Liquid Cooling:This method offers higher heat dissipation efficiency, allowing the heat generated by the device to be carried away faster. Liquid cooling technology reduces the battery's temperature more efficiently, improving its performance and lifespan. Compared to the noise generated by a fan, the noise of liquid cooling is much lower.
Guchen's battery pack thermal management system maintains batteries within ideal temperature ranges, therefore improving the dependability, performance, and service life of modern energy vehicles.
