Abstract
The invention provides a protective cover structure of a storage battery which comprises a storage battery body. The protective cover structure comprises a first protective layer and at least one second protective layer, wherein the first protective layer is attached to the storage battery body in a covering manner and used for protecting, cooling and insulating the storage battery body and preventing the storage battery body from burst; the first protective layer is coated with the at least one second protective layer which is used for strengthening the protection of the storage battery body; therefore, the storage battery body can be protected, cooled and insulated and prevented from burst by the first protective layer, and the protection of the storage battery body can be strengthened by the second protective layer. Accordingly, the reliability of the storage battery can be improved, the service life of the storage battery can be prolonged, the purpose of expected storage battery protection is achieved by means of the first protective layer and the second protective layer, the protective layers are sufficiently used, and materials are saved. The invention further provides the storage battery and a production method of the storage battery.
Description
technical field [0001] The invention relates to the technical field of accumulators, in particular to an accumulator applied to an electric vehicle, a protective cover structure of the accumulator and a manufacturing method of the accumulator.
