The company’s mission is to provide smart, efficient, and sustainable energy storage solutions that empower users to integrate renewable energy, enhance operational efficiency, and contribute to a greener future.
The global transition toward green electrification has fundamentally altered the parameters of industrial energy procurement. EPC contractors, developers, and multinational manufacturers no longer look for standard off-the-shelf battery packs. The demand has shifted decisively to custom engineering, scalable LFP (Lithium Iron Phosphate) chemistries, and deep software-hardware integration. Modern industrial stakeholders require suppliers that can mitigate global supply chain fluctuations while providing comprehensive compliance certifications.
Ensuring raw material security via localized battery manufacturing. We mitigate geopolitically induced logistics delays and tariff barriers by coordinating a diversified and transparent component sourcing structure.
Meeting strict local jurisdictions requires certification standards such as UL 1973, UL 9540A, IEC 62619, and CE. We perform thermal runaway propagation tests to assure absolute safety in urban installations.
Providing optimized battery dimensions, dynamic C-rate capabilities, and high-performance software tailoring to blend seamlessly with various inverter topologies and SCADA systems.
Modern microgrids and utility stations are complex, requiring precise electrical stability, rapid response rates, and robust thermal protection. Hangzhou HK Charger engineers systems that act as the backbone for various energy-demanding scenarios, optimizing Levelized Cost of Storage (LCOS) and providing reliable backup capacity.
Heavy industrial users face severe demand charges. Our high-capacity battery solutions (ranging from 100kW/200kWh to multi-megawatt containers) discharge dynamically during peak utility hours, significantly reducing operating expenditures and providing instant UPS backup during localized grid failures.
Wind and photovoltaic installations suffer from natural intermittency. By incorporating smart energy management systems with our 40FT LiFePO4 battery storage, operators can store surplus energy during high-generation periods and discharge it smoothly, stabilizing voltage fluctuations at the substation level.
Integrating low-temperature condensing systems with local energy storage ensures cold rooms run smoothly. Similarly, high-power EV charging stations (200kW-360kW) utilize our stationary batteries as buffers to avoid overloading the local grid during simultaneous ultra-fast charging events.
Hangzhou HK Charger prioritizes rigorous engineering to maximize safety and extend cycle life. We continuously advance our modular designs, software integration, and structural safety to guarantee long-term asset reliability.
We utilize premium prismatic Lithium Iron Phosphate cells. LiFePO4 represents the pinnacle of safety for stationary deployment due to its robust thermal stability, low risk of oxygen release, and superior lifetime cycles compared to cobalt-based chemistries.
Our in-house developed Battery Management System continuously monitors cell voltage, temperature, and internal resistance. Through active current redistribution, the BMS prevents cell divergence, ensuring the entire pack ages uniformly and safely.
Large-scale enclosures require uniform temperature distribution. We implement advanced liquid cooling loops alongside intelligent HVAC climate control to keep cell-to-cell thermal variations within 3°C, extending battery lifespan.
Exporting state-of-the-art power electronics requires absolute compliance with local grids and strict international directives. Our production facilities maintain ISO 9001, ISO 14001, and ISO 45001 certifications. Every batch undergoes strict quality gates, from incoming cell sorting to final complete system testing under full load simulation.
Fully prepared for UL 9540 (system integration) and UL 1973 (battery modules). The manufacturing line strictly adheres to safety configurations mandated by the National Electrical Code (NEC) and NFPA 855 installation standards.
Systems compliant with CE-LVD, CE-EMC, and specific grid codes such as VDE-AR-N 4105. Equipped with dual-layer active protection, integrated surge protective devices (SPD), and earth fault monitoring.
All containerized solutions and custom battery packs carry UN 38.3 certifications, guaranteeing safety during international maritime, rail, and road transit. We handle dangerous goods shipping logistics seamlessly.

We employ a multi-layered safety architecture. At the cell level, we use premium LiFePO4 chemistry, which inherently possesses high thermal runaway thresholds. Dynamically, our smart BMS constantly monitors cell-level currents, voltages, and surface temperatures. Structurally, our packs incorporate high-strength sheet metal isolation, aerogel barriers between individual cells to mitigate thermal propagation, and localized pressure release valves with integrated flame arrestors. Liquid cooling plates are also deployed in utility configurations to maintain uniform temperature distribution.
We offer full engineering support for regional compliance. During the system design phase, we align our schematics with local grid standards like UL 9540 for the USA and CE/EN guidelines for Europe. Our factory conducts strict pre-testing routines under simulating loads. We provide complete testing reports, listing files, and technical documentation required for local electrical inspections, simplifying the certification process for your projects.
An integrated hybrid system streamlines installation by eliminating the need for external DC-to-AC conversion steps. This direct architecture minimizes conversion efficiency losses, simplifies site wiring, and minimizes points of failure. Additionally, unified communications between the inverter and BMS enable faster response times for load balancing and grid backup, providing seamless backup transitions in under 10 milliseconds during outages.
Yes, our systems are built on modular, scalable architectures. We manufacture standardized cabinet modules (such as 215kWh and 233kWh units) that can be paralleled in modular configurations. For megawatt-scale requirements, we construct custom 20FT and 40FT containerized battery energy storage systems (BESS) equipped with localized fire suppression, HVAC systems, and centralized Energy Management Systems (EMS) to interface with existing SCADA installations.
Passive balancing dissipates excess energy from high-voltage cells as heat through resistors, which is less efficient and adds thermal load to the pack. Our Smart BMS uses active balancing, transferring charge from high-voltage cells to low-voltage cells via capacitive or inductive circuits. This active transfer minimizes heat generation, improves overall system efficiency, and maximizes the usable capacity of the battery pack over its operational lifespan.
As a dedicated OEM manufacturer, we design and produce custom battery modules tailored to specific mechanical, electrical, and thermal requirements. Our engineering team designs custom structural enclosures and optimizes cell configurations to fit restricted spatial dimensions, ensuring compatibility with applications ranging from automated parking towers to cold storage equipment.
