Heat Diminishes Your EV Performance

( 03/20/2018 ) Written by: Eric Wyman

When weighing their Electric Vehicle (EV) options, consumers often make decisions based on key performance metrics, including how far their vehicle can go on a single charge. Auto manufacturers are responding to this demand by increasing battery energy in their EVs, which results in longer ranges and, unsurprisingly, increased thermal concerns.

 

Increased Heat Concerns in the EV Industry

With EVs being a relatively new technology, there are still manufacturers and designers who consider thermal management an unnecessary cost. However, unlike conventional gasoline-fueled vehicles, controlling the heat of an EV’s components with thermal management solutions is critical to the efficiency, durability and even safety of the vehicle. As new generations of EVs are rolled out, automakers are realizing the importance of thermal management, particularly in the models touting higher-range capabilities or fast charging.

 

Ignoring Thermal Management Will Cost You

Heat is of particular concern for any EV design engineer; it degrades vehicle components, reduces battery charge rate (resulting in an increased charging time) and can even cause damage to the temperature-sensitive lithium ion batteries if they overheat. As auto OEMs race to release longer range EVs, a similar race is being held to develop increasingly effective thermal management designs and solutions to combat rising temperatures within the drive train. Controlling and reducing the temperature of electric components has drastic and measurable results: the rule-of-thumb is that every 10-degree-Celsius reduction in temperature effectively doubles a component’s life.

 

Advances in EV Thermal Management Solutions

As thermal management has primarily been used for microelectronics, this has led many in this particular market to take their existing gap filler technology and scale it up for use in vehicles. However, using decades of experience of working in the automobile industry and with the input from automakers, LORD has developed gap filler solutions designed specifically for large-volume applications like EVs. The next wave of Thermal Interface Materials (TIM) solutions for the EV industry is heavily swayed towards liquid dispensed gap fillers. They have a lower interfacial resistance and can be applied in whatever pattern to fit whatever design change. The thermal performance of the gap filler is also independent on the part tolerances.

 

The EV industry is rapidly growing and improving, but one constant remains: the need to combat overheating. Thermal management solutions such as gap fillers can help EV designers and automakers beat the heat, enabling the peak performance that EV consumers expect.

 

LORD engineers are available to assist you in finding the best cost-targeted solution for your thermal management needs, helping optimize your process and improve performance.
