Our turnkey delivery model manages the entire supply chain process, from factory acceptance and crating to sea freight and on-site commissioning support, ensuring a hassle-free experience for our partners.

Product Overview & Safety Architecture

The core of the EV Charging Plug is its robust, multi-layered safety architecture, built to protect both the investment and the operational environment. It proactively mitigates risks at every level, from the individual cell to the entire system.

Multi-Level Safety Framework

• Cell-Level Protection: Utilizes intrinsically safe, Tier-1 LFP prismatic cells with a proven track record of thermal stability. Each cell is individually monitored for voltage, current, and temperature.
• Module & Pack-Level BMS: A distributed, 3-tier BMS architecture provides active cell balancing and real-time diagnostics. The system is designed to automatically isolate faulty modules to prevent propagation of any thermal events, ensuring operational continuity.
• System-Level Fire Suppression: The EV Charging Plug is equipped with an Aerosol-based fire suppression system that is non-toxic, non-corrosive, and requires no high-pressure piping, guaranteeing total protection for the enclosure and surrounding assets.
• Robust Enclosure: Housed in an IP65-rated, lockable outdoor enclosure with C5 corrosion protection, the system is protected from water jets, dust ingress, and harsh environmental conditions, ensuring reliable outdoor operation.

Intelligent Liquid Cooling System

Operating at an ambient temperature range of -20°C to +50°C, the advanced liquid cooling system is critical for maintaining the LFP cells at their optimal operating temperature (23°C ± 2°C). This precision thermal management significantly reduces cell degradation and extends calendar life. By preventing hotspots, it ensures uniform aging of cells, which directly contributes to the exceptional cycle life and the robust 10-year performance guarantee.

Application Scenarios

The EV Charging Plug is engineered to address the most challenging energy demands across a diverse range of commercial, industrial, and infrastructure projects. Its modular design allows for easy scalability to meet growing energy needs.

EV Supercharging Stations

Integrating the EV Charging Plug directly with high-power DC fast chargers is an optimal solution to overcome grid limitations. By acting as a buffer, the system stores low-cost energy overnight and supplements the grid during peak demand, enabling stable operation of up to 4 simultaneous 150kW chargers. This maximizes station throughput and operational profitability.

Industrial & Manufacturing Parks

Facilities with heavy machinery and continuous production lines can deploy the EV Charging Plug to ensure power quality and reliability, effectively managing voltage dips and sags. The system’s black-start capability provides critical backup power for essential operations during unexpected grid outages.

Renewable Energy Integration

For solar-plus-storage projects, the EV Charging Plug captures excess solar generation, maximizing self-consumption and reducing reliance on the grid. This contributes to a lower carbon footprint and aligns with corporate sustainability goals and regulatory compliance.
