Mobile EV Charging Trailer | Mobile ESS Vehicle

Product Introduction

Mobile energy storage vehicles (trailer type) have become an important component of modern energy solutions due to their high mobility, large capacity, intelligent management, and environmental protection and energy conservation advantages. They are widely used in emergency, outdoor, and temporary power scenarios.

The Topband Mobile EV Charging Trailer is a towable energy storage and charging solution engineered for emergency response, remote construction, and EV fleet support. Built on Topband’s “1 Cell 1 Cloud 3S” architecture (cell, cloud, BMS/PCS/EMS), it uses LiFePO₄ battery modules rated for 4,000+ cycles.

mobile EV charging trailer and mobile ESS vehicle

Application

The mobile EV charging trailer acts as an emergency power backup and EV rapid‑charging solution, a mobile ESS vehicle for temporary construction‑site supply, outdoor‑events support, and grid‑stabilization applications.

: Emergency power supply and power protection

: Uninterrupted operation of the power grid

: Emergency charging for electric vehicles

: Outdoor and temporary construction electricity

: Emergency rescue and disaster relief

: Distributed energy and microgrid

: High mobility

Designed as a mobile EV charging trailer, it can be easily towed by standard vehicles across varied terrains and deployed in minutes. As a versatile mobile ESS vehicle, it excels in remote areas, disaster sites, and any scenario beyond the reach of fixed power grids.

: Multi output interface

Equipped with an intelligent monitoring system that supports local data collection, remote operation and maintenance, and OTA upgrades.
Support big data operation and maintenance, power grid dispatch and control, and remote monitoring.

: Intelligent management

Advanced intelligent management on the mobile EV charging trailer and mobile ESS vehicle integrates a high‑precision BMS for real‑time monitoring of battery voltage, temperature, and state‑of‑charge—ensuring safe, reliable operation. Cloud‑enabled remote monitoring and OTA firmware updates streamline control and maximize fleet management efficiency.

: Safe and reliable

The mobile EV charging trailer and mobile ESS vehicle employ multi‑layer protection—overcharge, over‑discharge, short‑circuit, over‑temperature, and leakage safeguards—to guarantee user and equipment safety. Housed in an industrial‑grade, IP54‑rated shell with shock‑resistance, waterproof, and dustproof features, it thrives in the harshest field conditions.
