The problem of above, mainly there are two kinds of approach to solve the cold temperature deficiency of lithium ion battery at present：One kind be use various energy resources for
Automobile provides power；Another kind is the new battery chemistries of exploitation.But above two method all has the short slab of its own.
For hybrid power, due to still using gasoline can also discharge a part of tail gas as fuel to air, be not strict
Clean energy vehicle in meaning.For second method, the construction cycle is long, application cost is too high turns into the short of its maximum
Plate.
