Abstract
The invention relates to the technical field of power batteries, and provides a manufacturing method of a power battery bottom protection plate, a battery box body and electric equipment, and the manufacturing method comprises the following steps: cleaning: cleaning a to-be-processed surface of a power battery needing to be provided with the bottom protection plate; a fence is arranged, the fence is arranged on the power battery, the shape of a forming space defined by the fence is matched with the shape of the to-be-machined surface, and the to-be-machined surface is arranged upwards; pouring is conducted, specifically, prefabricated liquid used for being solidified to form the bottom protection plate is prepared, the prefabricated liquid is injected into the forming space, and the to-be-machined surface is covered with the prefabricated liquid; and the fence is dismantled, and the fence is dismantled after the prefabricated liquid is solidified and formed. According to the scheme, the assembly efficiency is higher, higher integrity and compatibility are achieved between the solidified and formed bottom protection plate and the power battery, application and popularization are facilitated, and the production cost is reduced.
