What changed

This document is a patent application filing from the USPTO for a novel portable electric vehicle (EV) charging system named EnerJet Pro. The application details a Level 2 charging system that integrates an inverter, a modular lithium-ion battery pack (10-40 kWh capacity), and compatibility with renewable energy sources like solar and wind. It is designed to operate with a 240-volt AC supply and deliver up to 30 kW for rapid charging, supporting both grid-connected and off-grid operation.

As this is a patent application, there are no immediate compliance obligations for regulated entities. However, companies involved in EV charging infrastructure, battery technology, or renewable energy integration may find the disclosed technology relevant for competitive analysis, potential licensing opportunities, or future product development. The filing date indicates the start of the patent examination process, which typically takes several years before a patent is granted or denied.

Abstract

The present invention relates to a portable Level 2 electric vehicle charging system that integrates an inverter, a modular lithium-ion battery pack and renewable energy compatibility into a compact, weather-resistant housing. The system is configured to operate with an AC 240-volt supply and to deliver selectable power outputs up to 30 kW for rapid charging. The modular battery design allows scalable storage capacities ranging from 10 kWh to 40 kWh enabling both grid-connected and off-grid charging modes. A control system manages power delivery from the grid, the battery pack or renewable energy sources such as solar or wind through integrated charge controllers. The invention further provides hybrid charging capability, communication interfaces for monitoring and control and optional cooling systems to ensure safe operation. The portable design allows flexibility for residential, commercial and emergency use offering a reliable and scalable solution for electric vehicle charging.
