Product Overview
The INVT BE35L is a five-in-one electric vehicle controller developed for commercial vehicle platforms such as electric buses and other large electric transportation systems. It integrates key power electronics modules including the motor controller unit (MCU), DC/DC converter, oil pump controller, air pump controller, and high-voltage power distribution unit (PDU).
Traditional electric vehicle systems often require separate controllers for each auxiliary function, resulting in more complicated wiring structures, larger installation space requirements, and increased maintenance challenges. The BE35L addresses these issues by combining multiple functions into one integrated controller, providing a more efficient and reliable solution for electric vehicle manufacturers and system integrators.
With optimized hardware design and advanced control algorithms, the BE35L supports efficient motor operation and intelligent power management. It is suitable for modern electric commercial vehicles requiring high reliability, high efficiency, and long-term operation under demanding conditions.
Integrated Five-in-One Design
The main advantage of the INVT BE35L is its five-in-one integrated architecture. By combining several important electrical control modules into one product, the system can significantly simplify electric vehicle powertrain design.
Motor Controller Unit (MCU)
The integrated motor controller provides precise control of the electric traction motor. It manages motor speed, torque output, and operating efficiency according to vehicle control requirements. Through advanced motor control technology, the BE35L helps improve driving performance while maintaining efficient energy consumption.
The motor drive function supports stable operation during different driving conditions, including acceleration, cruising, and regenerative braking scenarios. This allows electric vehicles to achieve smoother operation and better energy utilization.
DC/DC Converter
The integrated DC/DC converter provides power conversion between the high-voltage battery system and low-voltage electrical systems. It supplies stable power for vehicle electronics, control systems, lighting systems, and other low-voltage components.
By integrating the DC/DC converter into the main controller, vehicle manufacturers can reduce additional components and simplify the electrical architecture. This improves system compactness and helps optimize vehicle space utilization.
Oil Pump Controller and Air Pump Controller
For electric commercial vehicles, auxiliary systems such as hydraulic oil pumps and air compressors require reliable electrical control. The BE35L integrates oil pump and air pump controller functions to support vehicle auxiliary systems.
This integration enables coordinated operation between the main drive system and auxiliary equipment, improving overall vehicle energy management. It is particularly suitable for electric buses and commercial vehicles that require continuous operation of auxiliary systems.
High Voltage Power Distribution Unit (PDU)
The integrated high-voltage distribution function provides centralized management of high-voltage electrical connections within the vehicle. It helps distribute power safely between the battery system, motor drive system, and auxiliary electrical loads.
By combining the PDU with other power electronics modules, the BE35L reduces external wiring requirements and improves the overall reliability of the vehicle high-voltage system.
