Shenzhen Ansar Energy Co., Ltd. stands at the forefront of the global energy transition, serving as a premier China Energy Storage for EV Charging Factory. Since our inception in 2015, we have redefined the integration of Electric Vehicle (EV) infrastructure and Battery Energy Storage Systems (BESS). Headquartered in the technological hub of Shenzhen, our mission is to mitigate grid instability and optimize renewable energy consumption for residential, commercial, and industrial stakeholders worldwide.
In the era of "Semantic Search" and user-centric energy demands, we provide more than just hardware; we deliver Information Gain through high-performance data and engineering excellence. Our 18,000-square-meter facility is the birthplace of innovative solutions ranging from 51.2V residential modules to 418kWh liquid-cooled industrial containers, all designed to stabilize the surging load demands of modern EV charging networks.
The synergy between Energy Storage Systems (ESS) and EV charging is evolving from simple backup power to intelligent Vehicle-to-Grid (V2G) and Peak-Shaving ecosystems. Ansar Energy's roadmap focuses on three critical pillars: Safety, Density, and Intelligence.
Transitioning from standard LiFePO4 to semi-solid-state and high-cycle prismatic cells, ensuring over 6,000 cycles at 80% DOD—vital for the high-frequency discharge cycles of EV fast-charging stations.
Our 372kWh to 418kWh systems utilize Liquid Cooling Technology. Unlike air cooling, liquid cooling maintains a temperature variance of <3°C between cells, extending battery life by 20%.
Ansar Energy integrates cloud-based Battery Management Systems (BMS) that use machine learning to predict cell failure and optimize energy arbitrage based on local utility price fluctuations.
Ansar Energy’s Shenzhen facility represents the pinnacle of Smart Manufacturing. By adopting "Factory 4.0" principles, we ensure that every lithium-ion battery pack meets the highest reliability standards for global distribution.
Robotic precision in cell sorting and laser welding reduces human error, ensuring impedance matching across all packs for uniform performance.
By controlling the entire process from cell procurement to final system integration, we provide significant cost advantages and stable lead times despite global supply chain fluctuations.
Every unit undergoes 100% EOL (End of Line) testing, including thermal stress tests, vibration simulations, and high-voltage isolation checks.
For international buyers and energy developers, compliance is the cornerstone of reliability. Ansar Energy bridges the gap between Chinese manufacturing efficiency and local regulatory requirements in Europe, the Americas, and Southeast Asia.
We provide full documentation for UL9540A, CE, UN38.3, and IEC62619, ensuring seamless integration into local power grids and insurance approval.
Custom branding, tailored enclosure ratings (IP54/IP65), and specialized communication protocols (CAN/RS485/Modbus) for specific inverter brands.
We support Engineering, Procurement, and Construction (EPC) firms with site-specific designs, CAD layouts, and technical supervision during commissioning.
Our core product portfolio addresses the unique challenges of different energy sectors. Whether you are building a solar-powered home or a megawatt-scale EV charging hub, Ansar Energy has the solution.
Wall-mounted and stackable solutions (5kWh - 30kWh) that allow homeowners to store excess solar energy and charge EVs at night without drawing from the grid during peak hours.
Our 100kW/210kWh containerized BESS units allow businesses to reduce "Demand Charges" by discharging stored energy during peak operation times.
Robust 200kW-500kW systems designed for remote locations or telecommunications infrastructure where grid access is limited or unreliable.
Buffering the grid from the 150kW+ surge of DC fast chargers, ensuring the local transformer remains protected while delivering maximum speed to the vehicle.
