System Composition
1、 VCU: The integrated control core of the equipment. It collects all control signals and integrates power management, thermal management, drive safety and unified control interfaces, while providing external control interfaces.
2、 OBC rectifier unit: It converts industrial AC input into DC power to supply power for energy storage and inverter units.
3、Main Drive Controller: It features four-quadrant vector control and supports bidirectional motoring and generating operation.
4、All-in-one Controller: It integrates multi-motor control and supports asynchronous and synchronous motors, DC/DC converters and PDUs. It reduces components and harnesses and improves system reliability.
5、Braking Resistor: It is used for energy dissipation. Under extreme operating conditions, when the battery cannot fully absorb the electric power generated by the motor, the braking resistor consumes this surplus power.
6、Thermal Management Unit: It provides thermal management for the main drive controller, permanent magnet synchronous motor (PMSM), all-in-one controller and charging unit.
7、Power Harnesses and Liquid Cooling Pipelines: Used for interconnection between power equipment.
Technical Features
1、Paired with an energy storage system, it can meet the power supply requirements of edge-side high-power equipment. Energy recovery technology effectively reduces equipment power consumption.
2、The OBC enables controllable rectification with adjustable grid-side power. It delivers coordinated power supply from the battery and grid, and automatically distributes power according to operating conditions to balance power performance and power utilization efficiency.
3、Adopting new energy EV technology and a common DC bus design, this automotive-grade drive unit features high reliability, strong environmental adaptability and excellent anti-interference capability. It reduces the footprint of high-power equipment while improving operating efficiency. The compact driver is 50% smaller in volume than conventional industrial frequency converters. Its stability has been extensively validated in passenger vehicle and construction machinery applications.
Selection Instructions:Selection is available for either a complete system or individual components. The complete system consists of the OBC charging unit, main drive controller, all-in-one controller, energy storage system, braking unit, thermal management unit and VCU. Cables and thermal management pipelines are estimated based on site dimensions, with external control interfaces provided as standard.
