Innovation:
1. It is not just a simple replacement of the diesel engine with a motor, but the hydraulic system is thoroughly optimized.
2. Self-developed load-sensing dedicated control system with variable speed, large closed-loop feedback of hydraulic parameters, torque prediction and direct torque control, global power matching, on-demand oil supply, reduced throttling and overflow losses.
3. Multi-motor coordinated control, reasonable matching of motor load, optimized energy management, efficient operation; time-sharing, automatic idle stop, reducing energy consumption of motor and pump idle.
4. 540V high voltage solution, reduce electric current; high efficiency permanent magnet synchronous motor, intelligent door drive variable speed control, low heat generation, 20% energy saving than asynchronous motor.
5. Regenerative power generation for various negative loads, based on energy recovery of power lithium batteries, to improve energy efficiency of the whole machine.
Features:
·Low cost of use: The cost of electricity is about 20~30% of the cost of traditional engineering machinery.
·The battery system is safe, high-efficiency, long-life, and can be used normally for 8 to 10 years to solve the pain points that users care about.
·Lithium iron phosphate battery has a deep charge and discharge frequency of more than 4,000 times, and the service life is about 2.5 times of a ternary lithium battery, and 5 to 10 times of a lead-acid battery.
·Battery comes with a heating film and works normally in the environment of -30~+55°C (-22°F~131°F).
·218kwh large capacity lithium battery, charging 1.5~2 hours, continuous work for 8 hours.
