I am seeking innovative technologies or systems to actively manage the temperature of electric vehicle batteries, especially when parked in cold temperatures. Low temperatures reduce battery performance, safety, and lifespan, hindering global adoption of electric vehicles. Current thermal management systems are passive and ineffective. I need an energy-efficient, active system that can quickly and precisely heat batteries from any starting temperature. Both theoretical and practical solutions are welcome.
Maybe cascading TEG/TEC cells all over the battery bed. Would have the option to either COOL / HEAT the battery and also harvest a part of the generated heat by the same hardware component with no moving parts -> Highly reliable.
Not costly effective and increases mass considerably.
