Overview

This system is a versatile, battery-powered electric vehicle (EV) DC charger design for mobile charging. It serves as a "Virtual Gas Can," ideal for service companies and roadside assistance, enabling vehicle charging in locations without access to permanent charging stations. The charger can be powered by a 48V battery stack, and the optional Bluetooth® feature eliminates the need for a control panel, reducing costs while providing charger status updates.

System Benefits​:

  • Level 2 support for faster remote charging time per mile.
  • Bluetooth interface for smartphone/tablet connectivity to monitor status.
  • Compact and portable design for easy transportation.
