Description

EVPBDP0001 Electric Vehicle High Voltage Power Distribution Unit (PDU)

EVPBDP0001 is a high-voltage Power Distribution Unit (PDU) specially designed for pure electric vehicles (BEV), hybrid electric vehicles (PHEV), and fuel cell vehicles (FCEV). As the “nerve center” and “power dispatching center” of the vehicle’s high-voltage system, it is responsible for efficiently and safely managing and distributing high-voltage electrical energy from the power battery pack, providing reliable power supply for key high-voltage accessories such as drive motors, air conditioning compressors, DC chargers (DC-DC converters), and PTC heaters.

This product, with its high integration, high safety and reliability, has become a key component for enhancing the performance, driving range and safety level of electric vehicles.

Highlights of core products

Highly integrated design
The “All-in-One” solution integrates multiple functions such as the main contactor, pre-charge circuit, Fuse, current sensor, high-voltage interlock circuit (HVIL), and manual maintenance switch (MSD) into one.

◦ Space and weight savings: The highly integrated modular design significantly reduces the number of wiring harnesses and connection points, lowers system complexity, saves valuable vehicle layout space, and contributes to lightweighting.

2. Outstanding safety and reliability
Comprehensive electrical protection: Equipped with high-performance DC fuses and contactors, it can quickly break short-circuit currents and overload currents, effectively protecting high-voltage lines and downstream electrical appliances.

High-voltage Safety interlock (HVIL) : It monitors the connection status of all high-voltage connectors in real time. Once an abnormal disconnection is detected, it immediately disconnects the main circuit and reports the fault to prevent the risk of plugging and unplugging while powered on.

Insulation monitoring function: An optional insulation monitoring module can be equipped to continuously monitor the insulation resistance of the high-voltage system to the vehicle body, ensuring the safety of passengers.

◦ Water and dust resistance rating: It usually has a protection level of IP67 or higher to ensure stable operation under harsh working conditions.

3. Intelligent control and status monitoring
◦ Intelligent control: Communicate in real time with the vehicle control unit (VCU) or battery management system (BMS) through CAN (Controller Area Network) or LIN bus, receive instructions and intelligently control the on-off of contactors in each circuit.

Real-time status feedback: It can upload information such as total voltage, total current, contactor status, and fault codes to the vehicle network, achieving fault early warning and remote diagnosis.

4. High performance and low power consumption
Low contact resistance: The high-power contactor with high-quality silver alloy contacts has extremely low contact resistance, effectively reducing energy loss and increasing the driving range.

Low-power design: The contactor coil maintains low power consumption, reducing the power consumption of the 12V low-voltage battery.

Brief description of Working principle

1. Electrical energy input: High-voltage electrical energy is output from the power battery pack and connected to the total input port of the PDU.
2. Intelligent allocation: The vehicle controller sends instructions to the PDU via the CAN bus based on the vehicle’s operating status (such as starting, driving, charging, and stopping).
3. Safe connection: After receiving the instruction, the PDU controls the pre-charging circuit and the main contactor to close in sequence to avoid inrush current impact, and smoothly distributes high-voltage electricity to the motor controller (driving the vehicle), DCDC (supplying power to the low-voltage system), air conditioning compressor and other loads.
4. Real-time monitoring: Throughout the entire process, the sensors inside the PDU continuously monitor voltage, current and insulation status to ensure absolute safety.
