Adopting advanced 1200V Field-Stop IGBT chips, the charger achieves a conversion efficiency of up to 97.2%, with 15% lower switching loss than traditional industrial chargers. The low saturation voltage characteristic of IGBT effectively reduces conduction loss, maintaining over 96% efficiency even in high-power working conditions, minimizing energy waste during the charging process and significantly cutting electricity costs for 24/7 operating energy storage systems.
Equipped with 1200V/40A high-voltage and large-current IGBT components, the charger realizes high-power output in a compact structure, with peak power reaching 3 times the rated power. It supports a wide DC voltage input range and can charge the battery to 80% of its capacity in only 15 minutes, perfectly meeting the fast charging demand of high-power battery systems in new energy storage and electric vehicle fleet operation scenarios, and greatly shortening the battery charging downtime.
The IGBT modules adopt a robust industrial package design, with a stable working temperature range of -40℃ to 175℃ and 0.3ms short-circuit withstand capacity. Built-in fast recovery diodes effectively prevent overvoltage and overcurrent faults, and the excellent anti-interference performance ensures stable operation in complex electromagnetic and harsh industrial environments such as factory workshops and outdoor energy storage stations, with no failure for more than 100,000 power cycles.
Based on PWM precise control technology, the charger realizes three-stage intelligent charging (constant current, constant voltage, floating charge), with adjustable AC charging current of 0-45A, which can be perfectly matched with the charging curves of various industrial battery types. It outputs pure sine wave with a total harmonic distortion of less than 3% for linear loads, avoiding battery damage caused by unstable current, and extending the service life of industrial batteries by more than 20%.
The optimized IGBT switching frequency and circuit design make the no-load loss in battery mode less than 1% of the rated power, and even lower to ≤10W in energy-saving mode. The charger supports intelligent power adjustment according to the battery state, automatically reducing power consumption in light load conditions, which is more energy-saving and environmentally friendly for the long-term continuous operation of industrial energy storage and backup power systems.
Ideal for lithium-ion and lead-acid battery energy storage projects of commercial complexes and residential communities. Its high-efficiency conversion and low no-load loss ensure stable charging and discharging of the energy storage system, perfectly matching the peak shaving and off-grid power supply needs of commercial and residential areas, and the reliable 24/7 operation performance meets the continuous power supply demand of modern building energy systems.
Perfect for fast-charging stations of electric car, bus and logistics vehicle fleets. The 15-minute 80% fast charging capability greatly improves the charging efficiency of fleet vehicles, and the pure sine wave output effectively protects the vehicle power battery, reducing the maintenance cost of the fleet’s power battery, which is a core charging device for urban public transport and logistics distribution fleet operations.
Suitable for charging batteries of industrial machinery such as forklifts, cranes and automated guided vehicles in factory workshops. With -40℃ to 175℃ wide temperature adaptation and anti-interference design, it operates stably in dusty, vibrating and other harsh factory environments, ensuring the continuous power supply of industrial handling equipment and supporting the uninterrupted production of factory assembly lines.
Complements off-grid renewable energy setups in remote areas such as mountainous villages, pastoral areas and outdoor workstations. It efficiently converts DC power from solar panels and wind turbines to charge storage batteries, solving the problem of unstable energy input of renewable energy, and ensuring a stable and continuous power supply for remote area production and living and outdoor industrial operation stations.
Critical for the backup power systems of hospitals, data centers and communication towers. The high-reliability IGBT design and fast charging performance enable quick activation of the backup battery during power outages, guaranteeing the uninterrupted operation of medical equipment, data servers and communication base stations, and providing a safe and reliable power guarantee for critical social operation facilities.
