Buy Liquid-Cooled Energy Storage | High-Efficiency C&I BESS for EV Charging

Product Summary

Introducing the next-generation Liquid-Cooled Energy Storage System (C&I Series) – a high-density, utility-grade BESS engineered for maximum ROI in demanding commercial, industrial, and EV fast-charging environments. Each cabinet delivers from 215kWh to 3.73MWh of usable capacity with a robust 1C discharge rate, powered by automotive-grade LFP (LiFePO4) cells. This system is purpose-built for peak shaving, demand charge reduction, and reliable backup power, offering a 10-Year Performance Warranty and ultra-low LCOE. Ideal for industrial parks, supercharging hubs, and micro-grids, it supports full turnkey integration with PV and charging dispensers.

Why Choose This System

Unmatched ROI & Total Cost of Ownership

Our liquid-cooled architecture ensures a daily usable throughput of ≥92% and a cycle life exceeding 8,000 cycles at 80% DoD. This translates to a >15-year operational lifespan, reducing the Levelized Cost of Storage (LCOS) by up to 22% compared to traditional air-cooled systems. By automating peak shaving and valley filling, your commercial facility can cut demand charges by 30-45%, with integrated EMS providing real-time energy arbitrage signals.

Risk-Free Global Procurement

We deliver end-to-end supply chain reliability: EXW, FOB, CIF terms available with lead times of 4-6 weeks for standard 372kWh cabinets. All systems include local O&M support via our certified partner network across EU, NA, and SEA. Our turnkey PV-Storage-Charging kits are pre-commissioned in our smart factory, slashing installation costs by 40%.

Product Overview & Safety Architecture

The Liquid-Cooled Energy Storage integrates a closed-loop liquid cooling system that maintains cell temperature variance within ±2°C, enhancing safety and calendar life. The 4-layer safety architecture includes: 1) Cell-level thermal fuses, 2) Module-level fire-retardant pads, 3) Aerosol + perfluorohexanone fire suppression (NFPA 69 compliant), and 4) Rack-level DC circuit breakers. The active balancing BMS offers 1,000Hz sampling rate, real-time SoC/SoH estimation with <2% error, and remote firmware OTA. Multi-stage protection against overcurrent, short circuit, and ground faults ensures rigorous UL 9540A compliance ready.

Application Scenarios

EV Supercharging Stations

Integrate seamlessly with 150kW-480kW DC chargers. Our BESS buffers grid demand, reducing transformer upgrade costs by 50% and enabling ultra-fast charging even on weak grids. The <2ms grid-to-island switching supports black start for charging infrastructure.

C&I Industrial Parks & Factories

Capture solar overproduction and shift low-cost off-peak energy to high-tariff peaks. With EMS including load forecasting and demand response, factories achieve payback within 3-4 years on high-intensity operations (welding, stamping, cold storage).

Micro-grids & Island Systems

As the main energy router, this liquid-cooled BESS stabilizes diesel-PV hybrid systems, featuring seamless grid-forming capability (VF source) and support for black start, accepting up to 120% unbalanced load.

Frequently Asked Questions

Q1: What is the standard lead time and shipping availability for the Liquid-Cooled Energy Storage system?

A: Samples (≤372kWh) are 4 weeks EXW. Full container orders for >1MWh are 6-8 weeks. We ship globally via sea freight to all major ports (Rotterdam, LA, Singapore, Shanghai). Door-to-door DDP service available across EU and North America.

Q2: How does the 10-year performance warranty work? What is the guaranteed end-of-warranty capacity?

A: Our warranty guarantees ≥70% of nominal capacity at 60% DoD daily cycling (8,000 cycles) or 10 years, whichever occurs first. For low-cycle applications (peak shaving only), the calendar warranty extends to 12 years. Replacement units are shipped proactively.

Q3: Can this system operate off-grid or island mode? What is the switching time?

A: Yes. The hybrid inverter + EMS supports seamless grid-tied and island switching within <6ms (tested to IEC 62116), allowing uninterrupted power to critical loads. It also supports full black start without external generators.

Q4: What grid certifications and compliance does this model hold for international markets?

A: It meets UL 1973, UL 9540, UL 9540A (cell-to-unit thermal runaway test), IEC 62619, IEC 62477, VDE-AR-N 4105, and CE/RoHS. We provide complete compliance documentation for local utility interconnection applications.

Q5: Do you offer turnkey PV-Storage-Charging solutions? Can you provide remote commissioning and local maintenance?

A: Absolutely. The Liquid-Cooled ESS is the core of our pre-designed kits: PV (up to 500kWp DC coupled), BESS (372kWh-1.5MWh), and EV dispensers (2x120kW). We offer worldwide commissioning support via AR remote assistance and local O&M partners in 24 countries.
