Mobile Energy Storage System Technology Project Overview

This document outlines a mobile energy storage charging system project designed for rapid rescue of faulty electric vehicles. The system is mounted on a 20-foot flatbed trailer with a trailer head, offering high maneuverability. It supports AC limit, AC priority, and DC priority modes for unattended automatic mode switching. The system integrates a 720KW/1.49MWh battery pack using lithium iron phosphate cells with a cycle life of over 6000 cycles and a lifespan of at least 10 years. Key components include a battery management system (BMS) with three-level architecture, thermal management with four air conditioning units, a perfluorohexane fire extinguishing system, and power conversion systems (PCS) rated at 100kW each. The design emphasizes modularity, high energy density, safety, and ease of maintenance. The system can function as a fixed charging station or mobile unit, with flexible trailer head configuration. Remote monitoring is enabled via video surveillance. The project aims to reduce energy consumption, cost, and floor space while ensuring operational safety and efficiency.
