Apart from the battery, why is the electric drive system also a key component in the development of new energy vehicles?

The development of new energy vehicles cannot be separated from the collaborative effect of the "three electric systems", which include the battery, motor, and electronic control as the three core components. From the perspective of the general public, battery technology has always been of great market concern. And as an important part of the "three electric systems", the motor and electronic control also play significant roles in power output, precise control, and system coordination. For new energy vehicles, the high-efficiency and high-reliability electric drive power system directly affects the power performance, driving experience, and long-term stability of the entire vehicle.

The electric drive system plays a role in power output, precise control, and energy conversion for electric vehicles.

And different vehicle models have different requirements for the electric drive system:

• Urban logistics vehicles need stability during long-term operation;
• Engineering and special vehicles need stronger load capacity and reliability;
• Passenger vehicles need smoother power response and precise control.

To meet these practical application needs, the coordination and cooperation among the motor, electronic control, and the entire vehicle system are required.

To assess whether an electric drive solution is mature and qualified, the following factors need to be considered:

• Motor performance;
• Control strategy;
• Installation space;
• System efficiency;
• Vehicle operating environment.

A complete electric drive system must ensure a proper matching of the synergy between the motor and the controller, achieving a balance among power output, control accuracy, and system efficiency, thereby helping the vehicle achieve higher operating efficiency, more stable power performance, and better driving experience.

 

As electric vehicles continue to evolve, more and more vehicle manufacturers are also pursuing more lightweight and efficient power system solutions.

The integrated high-reliability EV drive system reduces the complexity of system installation while improving overall matching efficiency and operational reliability. Compared to traditional solutions, the integrated design brings significant advantages to the power system structure:

• Optimizes the vehicle space layout;
• Reduces the difficulty of system integration;
• Enhances the stability of the power system;
• Simplifies subsequent maintenance requirements.

The WISE drive system adopts a two-in-one design concept of motor and control, achieving a more compact system layout through a crankshaft direct connection structure, while featuring high reliability and an architecture design that meets ISO26262 functional safety requirements, providing a stable, safe and efficient power solution for new energy vehicle projects.

For commercial vehicles and electric vehicles that require long-term operation, highly integrated electric drive systems can effectively reduce development complexity and enhance the overall application value of the vehicle.

 

The motor is one of the core components for power output in new energy vehicles. It has a direct impact on the vehicle's acceleration capability, operating efficiency, and driving experience.

During the development of new energy vehicles, the performance of the motor needs to be comprehensively evaluated:

• Torque output capacity;
• Heat dissipation performance;
• Installation space;
• System weight;
• Overall efficiency.

As vehicle requirements for lightweight and high performance continue to increase, the motor needs to achieve higher output capacity within a limited space. The lightweight electric drive motor for cars adopts a lightweight design concept, which can help vehicle manufacturers optimize space utilization, improve system efficiency, and reduce vehicle weight.

The WISE motor uses flat-wire winding technology, optimizing electromagnetic design to increase motor power density while reducing system weight. This enables the product to achieve higher performance output within a limited installation space, making it more suitable for applications in new energy vehicles with high requirements for efficiency, space, and power performance.

For various electric vehicle applications, lightweight and high-power density motors bring significant improvements to the vehicle, enhancing the vehicle's power performance and optimizing the interior space layout.

 

The motor is responsible for power output, and the controller is responsible for precise power regulation.

The motor controller needs to adjust current, voltage, and torque output in real time and optimize power response based on the vehicle's operating status to ensure stable operation of the vehicle under different conditions.

In the development of electric vehicles, the controller affects the vehicle's power performance, control accuracy, and operational reliability.

Automotive-grade motor controllers for electric vehicles can achieve more precise power management through advanced hardware design and intelligent control strategies, and improve system operational stability.

The WISE controller uses automotive-grade IGBT technology and combines intelligent algorithm protection mechanisms to achieve:

• More precise torque control;
• More stable low-speed operation performance;
• More comprehensive system protection capabilities.

At the same time, the controller architecture complies with ISO26262 functional safety requirements and can meet the higher demands of new energy vehicles for safety, reliability, and long-term operational stability.

For OEM customers, high-quality controllers need to achieve power control, and more importantly, ensure the vehicle maintains stable operation throughout its lifecycle.
