From product portfolio planning, the underlying logic of core technologies and rigorous certification systems, to scientific selection and full lifecycle value, this article provides an in-depth analysis of how Frey utilises its proprietary smart charging technology to deliver efficient, stable and safe energy supply solutions for industrial and mining lithium-ion power systems.
Product Portfolio – Targeted, scenario-based deployment; lithium-ion battery solutions for all scenarios
Against the backdrop of the widespread adoption of lithium-ion batteries in industrial vehicles and mining equipment, a single charging solution is no longer sufficient to meet the power requirements of diverse scenarios, operating conditions and specifications.
Drawing on its in-depth understanding of lithium-ion battery characteristics, equipment operating conditions and customer usage patterns, Frey has developed a clearly structured and precisely targeted range of smart chargers, covering everything from general industrial applications to specialised mining environments.
A Series | These smart chargers for low to medium power are designed for lightweight, decentralised charging scenarios, offering high versatility and flexible deployment.
Optimised for small- and medium-capacity lithium-ion battery systems, this solution balances efficiency and cost-effectiveness. It is compatible with a wide range of auxiliary equipment and is suitable for the daily recharging of light industrial vehicles, meeting diverse and intermittent charging needs.
B Series | Industrial Vehicle Chargers: Designed for the lithium-ion batteries of all types of industrial vehicles, including forklifts and AGVs, these chargers are precisely matched to the output characteristics, communication protocols and protection logic of these batteries, ensuring stable and reliable performance.
Each base model in the B Series can be expanded into specialised variants, enabling seamless integration into comprehensive factory lithium-ion battery solutions and meeting individual charging requirements.
MA Series | These chargers, specifically designed for mining lithium-ion battery systems, have been developed to meet the demanding conditions of both underground and open-pit mining operations, forming a seamlessly integrated solution with Frey’s range of mining lithium-ion battery products.
Meeting mining industry standards in terms of electrical safety, structural protection and environmental adaptability, they offer high reliability, a high protection rating and strong resistance to interference, providing professional charging support for heavy-duty mining equipment (this product series is currently in the development phase).
These three product ranges complement one another, covering both standardised mass-production scenarios and meeting bespoke and specialised requirements, thereby establishing an integrated ‘battery – charger – vehicle system’ solution.
Core Technology – Groundbreaking Advances at the Fundamental Level, Creating a Highly Efficient and Intelligent Charging Core
A charger is not merely a simple power supply device, but a crucial component in ensuring the safe operation, longevity and energy efficiency of lithium-ion battery systems.
With three major technological breakthroughs, Frey has comprehensively upgraded its charging performance, providing a stable and reliable power supply for all types of lithium-ion battery systems.
High-performance architecture and next-generation charging technology, leading the industry in efficiency.
The product incorporates high-efficiency topologies and control solutions developed for new energy vehicles, utilising advanced soft-switching and power factor correction technologies. Its overall energy conversion efficiency significantly exceeds the industry average. It maintains low losses and minimal heat generation even under high-frequency operating conditions, thereby delivering genuine energy savings and reducing long-term electricity costs for businesses, in line with the trend towards green factories and low-carbon mining.
Comprehensive intelligent temperature control, full environmental adaptability, and stable, uninterrupted operation.
Designed to cope with complex operating conditions in industrial environments—such as significant temperature variations, high dust levels and widely varying ventilation conditions—the charger is equipped with a comprehensive intelligent temperature control system. By continuously monitoring internal temperature distributions and dynamically adjusting heat dissipation strategies, it ensures fully adaptive operation across all environmental conditions.
Whether in high-temperature workshops or low-temperature working environments, it maintains a stable output of rated power, preventing derating, shutdowns or component ageing caused by abnormal temperatures, thereby ensuring the long-term, continuous and reliable operation of the equipment.
Full end-to-end autonomy and control, with in-house developed core technologies supporting continuous iteration.
From core control algorithms and power circuit design to key manufacturing processes, Frey has achieved full autonomy and control over the entire process of independent R&D and manufacturing of core charging station technologies.
Whilst reducing reliance on external technology, the solution offers rapid iteration and flexible customisation capabilities, enabling swift development in response to clients’ lithium-ion battery specifications, BMS protocols and equipment interface requirements, thereby providing a solid foundation for long-term technological upgrades and project implementation.
Quality Certification – Rigorous testing to international standards, ensuring safety and reliability
Safety is the absolute priority for industrial electrical products.
The Frey smart charging unit has obtained full CE certification, having successfully passed two key tests: the EMC (Electromagnetic Compatibility) test and the LVD (Low Voltage Directive) test.
EMC (Electromagnetic Compatibility) certification ensures that equipment does not interfere with surrounding electrical control systems in complex electromagnetic environments, whilst also remaining immune to external electromagnetic interference, thereby ensuring more stable operation;
LVD (Low Voltage Directive) certification comprehensively safeguards operational safety under low-voltage conditions, covering aspects such as electrical design, insulation performance and safety protection.
All product specifications meet internationally recognised standards, enabling them to meet the diverse requirements of domestic and international industrial projects and export applications, whilst ensuring the stable operation of customers’ equipment in terms of electrical safety and compatibility.
Scientific Selection – A Strategy for Precise Matching to Extend the Full Lifecycle of Lithium-Ion Batteries
The compatibility between the charger and the lithium-ion battery directly determines the battery’s lifespan and safety in use.
Frey has established a scientifically rigorous approach to charger selection, ensuring precise matching based on four key parameters: the rated capacity of the lithium battery, the system’s operating voltage range, the charging current requested by the BMS, and the standard charging rate.
Through precise, intelligent control of current, voltage and charging curves, the charger’s output characteristics are closely aligned with the battery’s electrochemical properties. This effectively prevents issues such as overcharging, undercharging and high-current surges, thereby mitigating battery degradation at source, significantly extending the overall service life of lithium-ion batteries, and reducing replacement and maintenance costs throughout their lifecycle.
Technology Outlook: Leveraging Charging as a Pivot to Deepen Engagement in the Smart Mobility Ecosystem
From in-house development of core technologies and the refinement of our product portfolio to our expert selection services, Frey remains firmly focused on our customers’ real-world scenarios, driving product upgrades through technological innovation.
The systematic launch of the smart charging station series marks a significant step forward for the company in its integrated ‘lithium-ion power + smart charging’ solution.
Looking ahead, Frey will continue to focus on the smart charging sector, further integrating intelligent features such as cloud-based monitoring, remote operation and maintenance, and group charging and control, to create a more efficient, intelligent and secure lithium-ion battery charging ecosystem. With more mature products and more professional technical services, we will work hand in hand with our partners to build a new future for the electrification of industry and mining.
