Bulk Chargers and Substations — Lesson 8

This lesson covers the concept of bulk chargers and substations, primarily used for charging multiple batteries simultaneously. It explains the need for high efficiency in these chargers due to the large power consumption and the importance of communication with batteries and servers. The lesson also discusses the two models of charging and distribution, namely, charging swapping and distribution at one space, hube and spoke. It further delves into the requirements for a successful swapping station, including communication with the central information management system and user communication. The lesson concludes with a discussion on the attempts to define international swapping standards and the importance of data analytics in improving subsystems and predicting potential faults.
