The lithium battery used in the new energy vehicle can not work directly at low temperature, so it is necessary to heat the battery to more than 5 degrees, otherwise it will greatly affect the service life and performance of the battery. At present, the heating equipment of lithium battery in the world is mainly water cycle heating, ceramic heating and metal plate heating. The high density graphene heating film has been developed innovatively by PMA group. The current generation of products has obvious advantages of stable energy efficiency, light weight and economical price. Any OEM or ODM information, please contact with us for more.
