Battery Charging Systems

This module will focus on the various types of battery chargers in use, including Level 1, 2 and 3 EVSEs.  It will also cover the five basic types of EV connectors and the principle of bidirectional charging.  In addition, the student will learn how to calculate charging time and charging cost. Upon completion of this module, the student will also  be able to describe the purpose of OCPP and the main considerations for commercial EVSE installations.  EVSE test equipment will also be discussed as well as the steps required to safely charge an EV.
