Heaters are Crucial to EV Battery Packs in Cold Temperatures!

Heaters are Crucial to EV Battery Packs in Cold Temperatures!

Batteries don’t properly function in cold weather, so what does this mean for an electric vehicle? Electric vehicle batteries cannot charge, and the packs lose half of their range when temperatures drop below freezing.

Caliente has created innovative heating solutions to solve these problems. Our heaters are designed to work with the electric vehicle’s existing cooling infrastructure to push heat back into the batteries. We have created three different heater variations: pad, immersion, and radiator. Pad heaters are applied directly with the cold plate, ceramic immersion heaters are submerged in the liquid path, and radiator style heaters sit in front of the air flow systems.

The pad heaters in particular offer several advantages. At 0.011”, they are extremely thin, adding heat with minimal impact to cooling performance. The watt density can also be tailored to add more heat where there are more losses, and minimize heat in hot spots. They are also much more cost effective when compared to flow through elements on liquid based systems, removing the isolation failure mode common with this technology.

“I really appreciate this and the extra efforts you’ve put into this purchase [of thermal targets] are the kind of things that make a company outshine its competitors in the market. We won’t forget this! Myself and the government office I support were very excited to find Caliente and I have really enjoyed working with everyone at the company.”
