Driven by the "dual-carbon" strategy, the electrification process of commercial vehicles is accelerating. High-frequency and high-power consumption scenarios such as heavy trucks and mining trucks pose higher requirements for the power density, scheduling efficiency, and environmental adaptability of charging equipment. The 1920kW intelligent power scheduling charging system launched by HARDHITTER provides operators with a charging solution that balances efficiency, flexibility, and reliability.

The system is designed based on a 1000V high-voltage platform with a rated power of 1920kW, supporting flexible configuration of 6-18 guns. The single-gun charging current is 300A, and the liquid-cooled ultra-fast charging terminal can output a maximum continuous current of 600A per gun, adapting to the fast energy replenishment needs of heavy trucks, mining trucks, and other large-capacity batteries. Through matrix power distribution technology, it can dynamically allocate the output power of multiple guns in real time, avoiding the problem of resource idleness caused by the fixed power of traditional single-pile chargers. When some vehicles complete charging, the remaining power can be automatically allocated to other terminals, significantly improving equipment utilization.

Equipped with intelligent power scheduling technology, the system can achieve module-level precise power distribution according to the vehicle BMS requirements, battery SOC status, and station load, with a maximum charging efficiency of 95.5%. Compared with traditional charging piles, the energy loss of the entire station is reduced, significantly improving the operational economy of the station.

The system adopts a modular architecture, with 48 40kW power units built-in, supporting total power improvement through parallel expansion to meet the future charging demand growth of the station. The charging terminal is compatible with the upgrade of liquid-cooled ultra-fast charging guns and reserves an interface for V2G function upgrade, laying a foundation for the integrated layout of photovoltaics, energy storage, and charging.

Heavy trucks have long daily driving distances and high energy replenishment frequencies. Traditional charging piles are limited by inflexible power distribution, easily causing queuing congestion during peak hours. HARDHITTER optimizes the process through the following solutions:

①Dynamic power allocation: The 1920kW power pool of a single machine can simultaneously meet the differentiated needs of multiple heavy trucks. For example, when a vehicle requires 600kW fast charging, the system can call idle modules for centralized power supply, and the charging speed is 85% higher than that of traditional dual-gun piles (320kW). ②Shortening energy replenishment time: Helping to increase the daily transportation frequency of vehicles.

②Shortening energy replenishment time: Helping to increase the daily transportation frequency of vehicles.

Mining truck operation environments are often accompanied by high dust, extreme temperature differences (-40°C to +60°C), and vibration impacts. The system ensures stability through multiple protection designs:

①Environmental adaptability: IP55 protection level, combined with a 40PPI high-density dust-proof net and fully potted modules, effectively resists dust intrusion; a wide-temperature intelligent cooling system ensures continuous output in extreme cold of -40°C and high temperature of 60°C.

②Active safety protection: 65 real-time monitoring functions cover risks such as overvoltage, reverse current, and ground faults. The boot self-check and dual protection mechanisms for output interfaces reduce the failure rate, adapting to the 24-hour continuous operation needs of mining areas.

The HARDHITTER 1920kW intelligent power scheduling charging system has been scaled application in heavy truck charging stations in Inner Mongolia, Shanxi, and other places.

With its modular architecture, intelligent scheduling core, and high-reliability design, the 1920kW intelligent power scheduling charging system solves the energy replenishment bottleneck in special scenarios such as heavy trucks and mining trucks, providing an expandable and sustainable technical foundation for the long-term operation of charging stations. HARDHITTER provides customized charging solutions for different scenarios, and promotes the standardization and intelligence of charging infrastructure through multi-dimensional value output.
