BTMS Battery Thermal Management System

The Battery Thermal Management System is a complete thermal system solution that maintains the critical operating temperature range of automotive batteries. Design solutions are available for both active and passive cooling circuits.

Function

The function of the battery thermal management system is to regulate the temperature of the battery in real time to maintain the battery working in the optimal temperature range to ensure the performance, life and safety of the battery. It is mainly categorized into the following situations.

1、Preventing overheating: When the battery temperature is too high, the battery performance will be affected and may even fail. The battery thermal management system can reduce the battery temperature in time through heat dissipation and other methods to prevent the battery from overheating.

2, to prevent overcooling: in a low-temperature environment, the battery performance will also be affected, and even can not work properly. Battery thermal management system can raise the battery temperature in time through heating and other methods to prevent the battery from overcooling.

3, to maintain the stability of the battery temperature: in the vehicle driving process, the battery temperature will continue to change, if the temperature fluctuation is too large, will have a negative impact on the battery performance. Battery thermal management system can control the coolant flow and other methods to keep the battery temperature stable.

4, improve battery life: by controlling the battery temperature within the optimal range, you can extend battery life. Reduce the number of replacements and lower maintenance costs.

Precise Thermal Management for Your Battery

Innovative battery electric (BEV) and fuel cell electric (FCEV) vehicles require precise management of battery temperatures to achieve the necessary range, performance, and longevity.

Our field-proven Battery Thermal Management System (BTMS) provides intelligent thermal regulation and is the solution of choice for many of the world's leading OEMs.

The BTMS (Battery Thermal Management System) of the whole battery consists of the cooling module, the heating module, the pump, the expansion water tank, the connecting pipe and the electric control. The cooling liquid is cooled (or heated) by the cooling module (or the heating module), and the cooling solution is circulated in the cooling system of the battery by the pump. The cooling module consists of an electric scroll compressor, a parallel flow condenser, a plate heat exchanger, a H expansion valve and a condensing fan. The cooling module and the heating module are directly connected in series to the system pipeline, and each part of the circulation system is connected through the body hot water pipe and the conversion joint.

1. Performance: the BTMS can measure and monitor the battery temperature in real time through the BMS system. The cooling and heating reaction speed is fast.

2. Energy saving: the refrigeration module electrical control system adopts advanced frequency conversion control technology and high efficiency DC frequency conversion scroll compressor, which is about 20% energy saving than ordinary compressor.

3. Environmental protection: BTMS is independent, using parallel flow condenser and plate heat exchanger, which make sure to have the refrigerant charge less.

4. High safety: the product has designed two stage insulation, high and low pressure and pressure relief protection device, which greatly guaranteed the safety of product use.

5. Easy installation: the BTMS does not need to refrigerate on site, and the body is connected with hot water pipes for easy installation.

6. High reliability: the control system adopts single-chip microcomputer control technology, mature and reliable. Long life, low noise, no maintenance, longer life than general brush fan, compressor design life of 15 years, low failure rate.

 7. PTC heating function, at low temperature, PTC electric heater heating, to ensure that products in the cold area can also be able to use.
