As the core component of the charging pile, the power module has strict restrictions on the installation position and is heavy. Each power module weighs dozens of kilograms. It takes a lot of manpower to install and transport it in the production and installation room. The production and installation workshop has limited space, and forklifts cannot meet this working condition.
