The EV industry lies at the cusp of global adoption. However, scaling up and sustaining this industry demands optimised solutions. Without efficient thermal management and heat overall heat regulation, battery overheating and efficiency are potential risks.
For the industry to grow exponentially, addressing the right ways to produce electrical vehicle batteries is paramount. Sustainable and efficient management ensures safety, performance and longevity.
Let’s explore how an advanced Battery thermal management system can improve overall EV performance.
Current Challenges in Battery Thermal Management System
Today, the electrical vehicle landscape relies on Li Ion battery cells. EV battery thermal interface materials are sensitive to temperature fluctuations, resulting in performance issues. Issues such as charge time, battery life cycle, and voltage fluctuations are all part of it.
A cold EV battery cell insulation chemical reactions slow down (below 0 degrees). Thus, resulting in discharge or reduction in capacity At 20°C or lower, the damage is irreversible. The electric vehicle thermal management system is also impacted at higher temperatures. Above 60 degrees, customers observe degradation in battery capacity. In extreme cases, it can cause a thermal runaway, leading to fire hazards or explosions.
Battery Thermal Management systems help maintain optimal temperature. When the battery temperature lies between 20°C and 45°C, battery longevity is superior.
The Balancing Act Between HVCH and Radiators
Traditionally, radiators were associated with engine cooling and have added functional roles. They are involved in maintaining temperature and ensuring system longevity. When High Voltage Coolant Heating systems work cohesively with radiators, the vehicle functions optimally.
The combination of radiators and HVCH is an impactful step in thermal innovation. It ensures sustainable Electric vehicle battery life and elevated driving experience.

Cooling Management Methods
Efficient thermal management systems demand effective electronic systems and cooling systems. Two main cooling categories involved include
- Active Cooling Method: Fans and blowers are an example of an active battery cooling method that is an industry standard. They are used in multiple applications. Liquid cooling systems include specialised fluids that ensure heat transfer from hotspots. Generally, these are used in EV battery packs. Thermoelectric cooling uses the Peltier effect to create temperature fluctuation. Often used in laboratory requirements.
- Passive Cooling Methods: Passive cooling techniques include the incorporation of heat sinks. Heat is dissipated using fins that broaden the surface area. Heat pipes is another way where a working fluid is used and the heat evaporates the heat and moves to the other end where it condenses. Thermal insulation, such as that used in EV battery cell to cell insulation, is another method. Additionally, applying protective coatings can further enhance heat dissipation.
