Electric truck BTMS stands for Battery Thermal Management System for electric trucks. It is a battery temperature control system designed specifically for electric trucks. This system cools or heats the battery pack to ensure it operates within the optimal temperature range, thereby improving performance, safety, and lifespan.
Cooling Cycle Operating Principle: An electronic water pump drives coolant through the cooling plates or liquid cooling pipes within the battery pack, absorbing heat generated by the battery. The high-temperature coolant is then transported to a plate heat exchanger, where it undergoes heat exchange with the refrigerant. The cooled coolant is then recirculated back to the battery.
Purpose of the Cooling Cycle: To rapidly cool the battery during high-power charging or discharging, preventing overheating and thermal runaway.
Heating Mode Circulation Principle: The refrigeration circuit is shut off, and the PTC heater is activated to directly heat the coolant. The high-temperature coolant transfers heat to the battery pack via pipes, ensuring normal battery operation in low-temperature conditions.
Purpose of the heating mode cycle: To enhance battery chemical activity in low-temperature environments using PTC heating, preventing range degradation.
Principle of the temperature equalisation mode: Multiple temperature sensors continuously monitor the temperature of each cell within the battery pack. The control system dynamically adjusts the coolant flow rate and cooling/heating power to reduce temperature differences between cells.
Purpose of the temperature equalisation mode: To reduce temperature differences between battery cells, prevent local overheating or overcooling, and extend battery lifespan.

Firstly, the core objectives of these two BTMS systems are consistent. Both aim to ensure that lithium-ion batteries operate within their optimal temperature range to prevent thermal runaway, maximise battery performance, extend battery life, and maintain vehicle range.
1. Cooling capacity
Electric truck battery packs are massive, with capacities typically five to ten times larger than those of passenger vehicles. This results in significant total heat generation. Additionally, heavy trucks require extremely high instantaneous power, such as during acceleration or hill climbing. Therefore, electric truck BTMS must be exceptionally well-designed to handle the extreme heat generated during heavy loads, high-speed driving, or rapid charging. The cooling system’s flow rate, heat exchange area, and radiator size all need to be significantly increased.
In contrast, electric passenger vehicles have relatively smaller battery packs and lower power requirements. Typically, a single cooling circuit or battery air cooling system is sufficient.
2. System Complexity and Cost
Electric truck BTMS have stringent cooling capacity requirements. The massive heat dissipation demands necessitate larger water pumps, compressors, heat exchangers, more coolant, and more complex piping. The system design complexity is higher, resulting in significantly higher costs compared to passenger vehicles.
Conventional electric vehicle systems are relatively simple, resulting in lower costs.
In summary, the BTMS for electric trucks is a more specialised solution designed to handle extreme thermal loads with stringent performance requirements. In contrast, the BTMS for passenger vehicles focuses on providing thermal management performance that meets daily needs within limited space and cost constraints.
