As early as 2018, we established a deep partnership with TATA Motors, 一筆財富 500 公司. We custom-developed a 9m electric bus air conditioner and electric bus BTMS. 經過多輪嚴格測試, we became their designated supplier of electric bus air conditioners and BTMS.
隨後, TATA Motors initiated another collaboration project with us for the BTMS system of electric trucks. These collaborations serve as a testament to our design capabilities, product quality, and after-sales support.

BTMS stands for Battery Thermal Management System. The electric bus BTMS is a core system specifically designed to regulate the temperature of the electric bus’s power battery. It ensures the battery operates within a safe and efficient temperature range to improve performance, extend lifespan, and avoid thermal runaway. Electric bus BTMS utilizes large-capacity power batteries, 產生大量熱量. 所以, liquid battery cooling systems are currently used.
TKT’s electric bus BTMS is fully automated. It communicates with the vehicle controller and battery management system via the CAN bus, synchronizing battery temperature data in real time and adjusting operating frequency.
The BTMS system for electric buses typically includes cooling, 加熱, 冷卻, and electrical systems.
1. The cooling system consists of a compressor, 冷凝器, 板式熱交換器, and water pump. It circulates the coolant to cool the battery.
2. The heating system uses a PTC water heater to heat the circulating fluid and warm the battery.
3. The cooling system includes an air-cooled radiator tank.
4. The electrical system includes the controller and wiring harness.
優點
1. 高效率散熱
The liquid has high thermal conductivity, quickly dissipating the large amounts of heat generated during charging and discharging. It is particularly suitable for high-temperature environments and large-capacity power batteries.
2. 優異的溫度均勻性
The battery cooling plate design provides a large contact area between the liquid and the battery, reducing local hot spots. This allows for precise control of inter-battery temperature differences and minimizes temperature differences.
缺點
1. High System Complexity
Requires integration of components such as water pumps, 管道, and seals, increasing weight.
2. High Cost
Requires more components, a more sophisticated design, and more complex assembly than air cooling.
優點:
1. Simple and Reliable Structure
No liquid circulation system is required; air flow is driven solely by a fan. Suitable for small battery packs or auxiliary cooling scenarios.
2. Low Cost
Lower production costs and no liquid replacement costs.
缺點:
1. Low heat dissipation efficiency.
Poor air thermal conductivity makes it difficult to control battery temperature in high-temperature environments (例如, above 45°C), which can easily lead to thermal runaway.
2. Poor temperature consistency.
Improper air duct design can result in temperature differences of more than 10°C between battery modules, affecting battery life and safety.
總之, the high-voltage power batteries in electric buses generate significant energy and heat, necessitating a liquid battery cooling system. Air cooling systems cannot meet these cooling requirements.
