The invention provides a leading-out insulating protection cover for a power battery. The protection cover comprises a protection cover body for containing a leading-out terminal, a first removable piece arranged at the end of the protection cover body and a positioning structure; the first removable piece is in removable connection with the end of the protection cover body; and the positioning structure is arranged at the side edge of the protection cover body. The invention also provides a power battery module containing the protection cover. According to the leading-out insulating protection cover for the power battery, provided by the invention, when the shape and leading-out direction of the leading-out terminal are changed, arbitrarily matching use can be achieved by utilizing a way of removing the first removable piece or a second removable piece, and the operation is simple, so that the universality in different modules is achieved, the research and development costs are reduced, and the research and development time is shortened.
Description
technical field [0001] The invention belongs to the field of power batteries, and in particular relates to a lead insulating protective cover for a power battery and a power battery containing the protective cover. Background technique [0002] In the context of the depletion of non-renewable resources such as petroleum and the increasingly serious environmental pollution, people place great expectations on new energy. Whether it is wind energy, solar energy, or electric vehicles, these new energy technologies that have attracted much attention are indispensable for battery modules that are used for energy storage or as a power source, so the performance of battery modules directly affects the development of current new energy technologies . The vehicle power battery is the most complicated to use, which puts forward extremely high requirements for the safety, reliability and low cost of the power battery pack. [0003] In order to achieve higher energy density and power d...
