Unlike gasoline-powered vehicles, electric vehicles (EVs) need accurate temperature management well beyond the impact of temperature control from the automotive temp control chiller, which is central to the management of heat across EV components, including batteries, motors, and power electronics. As development is thermal management, Liatem (https://www.liatem.com/) creates high-efficiency drives automotive temp control chiller units. Liatem makes automotive temp control chillers for EVs for dealing with battery overheating and range anxiety issues per battery overheating, EVs need range anxiety. Following are the key reasons why automotive temp control chillers are needed to control temperature in electric vehicles and the EV industry.
To Preserve EV Batteries and Maximize Their Useful Lifespan
The automotive temp control chiller must avoid battery temperature from exceeding certain levels, which because of the nature of lithium-ion batteries, calls for frequent temperature checks and possible adjustments. Lithium-ion EV batteries need to be maintained between 20-30°C (68-86°F) to avoid degradation (loss of capacity and shortening of useful life) of the battery. Batteries colder than 0°C need to be warmed to. Over 35°C (95°F) the battery is operating at its peak and must be controlled, degradation ensues. The automotive temp control chiller cools batteries needed for power at the automotive temp control chiller and drives during charge to keep the temperature from rising.
Liatem's automotive temp control chiller employs state-of-the-art refrigervent systems as well as advanced precision sensors that perform real time adjustments of cooling outputs. For instance, the chiller boosts its cooling during the 150kW fast charge to monitor the heat rapid energy transfer to the batteries generates. Without automotive temp control chillers, battery degradation would have EV owners would have to replace expensive packs much sooner. This degradation is a significant factor in the overall battery health associated cost and retained value of the vehicle.
Optimized Range and Performance of EV Batteries
The automotive temp control chiller is instrumental in optimizing the range of an EV and stable battery performance which are the two primary goals of most drivers. Overheated batteries significantly reduce the energy that can be stored and delivered. For instance, a battery operating at 40 degrees celsius will lose 15% of its range compared to a battery operating at optimal temperature. This automotive temp control chiller will keep batteries cool and prevent range loss.Liatem's automotive temp control chiller also pairs with heating systems during the winter months, but its cooling function is vital for range retention during warm weather. For example, an EV equipped with a properly functioning automotive temp control chiller can experience a 20% range improvement during summer heatwave compared to an EV without one. Furthermore, the chiller preserves battery performance when EVs rapidly accelerate, drive up steep grades, or perform other high load activities, which smooths the driving experience by avoiding sudden power dips. For EVs, stable performance and maximum range is critical making the automotive temp control chiller, an essential component.
Prevents Malfunctions by Cooling Power Electronics
As EVs operate, the power electronics which include the inverters, converters and onboard chargers generate a lot of heat and automotive temp control chillers prevent these components from overheating and malfunctioning. For example, an uncooled inverter which converts DC battery power to AC for the motor can reach over 100°C which can result in component failure or insulation breakdown. The automotive temp control chiller carries coolant to the heat sinks of the power electronics which helps maintain a safe operating temperature by drawing thermal excess heat.
Liatem’s automotive temp control chiller has dedicated cooling circuits built for each component in the power electronics, protecting and customizing the temperature management system for each cooling component, even if the battery and the motor have different cooling requirements. For instance, the chiller bypasses cooling circuits to prioritize excess heat generated during fast charging to prevent interruptions during charging. The automotive temp control chiller assists in protecting power electronics. This is vital to keeping the EV operational to avoid costly repairs. With power electronics failures being costly and leaving the EV inoperable, the automotive temp control chiller is essential for reliable EV operation.
Protects Electric Motors from Overheating and Efficiency Loss
With the help of an automotive temp control chiller, EV electric motors avoid overheating and energy efficiency is maintained. Motors handle heat from operation, but prolonged operation above 80°C spells danger. Overheating causes the copper windings to expand, increasing electrical resistance. The motor loses efficiency and the wasted energy is converted to heat, causing damage to the motor bearings. An automotive temp control chiller is capable of cooling the motor by passing coolant through the jacket or heat exchanger. With the automotive temp control chiller, Liatem is capable of maintaining the motor temperature within the 60-75°C optimal range. For example, during high-speed driving when the motor is under heavy load, the chiller increases coolant flow to match the heat output. Liatem’s automotive temp control chiller adjusts cooling based on motor load.
A motor that is cooled properly works at 5-8% greater efficiency than one that is not, resulting in a greater range and reduced energy consumption. Overheating motors is a problem, but automotive temp control chillers solve that and even extend motor lifespan, saving future maintenance costs.
Enhances Passenger Comfort by Managing Cabin Temperature
While the automotive temp control chiller was designed primarily for the critical components cooling, it also assists in cabin temperature control for comfort. During the warm season, the chiller works together with the EV air conditioning (AC) system to cool the cabin more effectively. The AC system does not drain the battery by pulling power directly, and the chiller cools the AC coolant beforehand, thereby lessening the energy demand of the AC. The automotive temp control chiller made by Liatem integrates with the cabin HVAC system to optimize energy usage by simultaneous cooling of the battery, power electronics, and cabin. For instance, on a scorching day, the chiller cools the battery and offers cool coolant to the cabin AC, ensuring passengers stay comfortable while preventing excessive battery drain. This is a perfect example of integrated system design for comfort of passengers while protecting components, which is an aspect of premium EV design. The automotive temp control chiller is a must since, without it, the AC system would ineffectively cool the cabin while drastically cutting the range.
Conclusion
An automotive temp control chiller is a crucial component for EVs. It protects power electronics and motors from overheating, improves passenger comfort, and maintains battery health and range.
Liatem specializes in providing high-performance automotive temp control chiller units that manage the distinctive thermal issues of EVs, paving the way for dependable, effective, and comfortable electric driving. With the growing adoption of EVs, the automotive temp control chiller will continue to address primary concerns including range anxiety and deterioration of batteries, forming the foundation of contemporary thermal management systems for EVs. For both car makers and EV drivers, the value and performance of their EV depends on the quality automotive temp control chiller.
