High Efficiency Diesel Generator

Battery Pack with Comprehensive Battery Management System (BMS)

Control Panel with State of the Art Integration System

Typical flow of power for Graphsyn Energy System:

Diesel generator runs and supply electrical power to Graphsyn energy storage system (GESS) and charge it up to 80% SOC.
GESS supplies power to support auxiliary load, hoist motor, trolley motor and gantry motor simultaneously.
Energy recovered from lowering spreader is stored back to the GESS System.
Cycle 2 to 3 repeats itself until Battery management system detects 20% SOC. Then, Diesel generator restart itself and charge GESS System.

Capable of delivering quick acceleration and smooth power delivery.
Lower Operating cost where hybrid retrofit saves about 30% in energy cost while full electric retrofit reach as high as 68%.
Drastically reduce annual general maintenance cost. (Above 50%).
Significant reduction in noise level. (Above 40%)
Major reduction in CO2 emission for Hybrid retrofit and zero CO2 emission for full electric retrofit.
Long battery life with comprehensive warranty. (Above 7 years).
Support renewable energy such as solar, wind or hydro energy (for full electric retrofit only).
Live data monitoring on battery status, working performance, charging station occupancy, error report and etc.
