What factors should be given priority consideration when purchasing electric drive products for new energy vehicles? How can WISE help customers reduce procurement risks?
Sep 30, 2026
As the global market for new energy vehicles continues to grow, more and more vehicle manufacturers are starting to focus on developing electric products. However, for vehicle manufacturers, the procurement of motors, motor controllers, and related electric drive products is of crucial importance. It is not merely a matter of randomly selecting a supplier and purchasing the products.
The electric drive system needs to operate continuously in complex working environments, and its performance directly affects the vehicle's power, safety, user experience, and brand reputation. Therefore, when choosing an electric drive supplier, the purchaser needs to comprehensively evaluate the product matching capability, quality system, R&D capability, delivery capability, and supply chain guarantee capability.
So, what factors should be focused on when purchasing electric drive products for new energy vehicles? As a supplier providing electric drive products to global vehicle manufacturers, WISE is committed to becoming an OEM-focused electric vehicle drive system supplier. Through product matching, technical support, and customized development capabilities, it helps customers reduce procurement risks.
1. Compatibility between the electric drive system and the entire vehicle
The impact of the power system of an electric vehicle on the entire vehicle is extremely significant. It is not merely a matter of simply installing the motor and electronic control unit on the vehicle to make it operational. The electric drive system and the entire vehicle must achieve a deep-level match to fully utilize its optimal performance.
Moreover, different types of vehicles have distinct requirements for the electric drive system:
· City commuting passenger vehicles focus more on efficiency, smoothness, and range performance;
· Commercial vehicles pay more attention to long-term operation capabilities, reliability, and load capacity;
· Specialized vehicles need to meet the stable operation requirements in complex environments;
· Two-wheeled and three-wheeled vehicles are more concerned about power response, cost control, and space adaptation.
Therefore, to ensure the smooth and reliable operation of motor vehicles, the electric drive product must achieve:
(1) Voltage platform matching
The electric drive system needs to be compatible with the battery voltage platform of the entire vehicle, such as 48V, 72V, 96V, and higher voltage levels.
At the same time, suppliers need to consider the voltage fluctuation range during actual operation to ensure the system operates stably under different conditions.
(2) Power performance matching
The output power, peak torque, and speed range of the motor need to be matched according to the vehicle's weight, load requirements, and applicable scenarios.
If the power parameters are insufficient, it will affect the vehicle's acceleration performance and climbing ability; if they are too high, it may lead to increased costs and energy waste.
(3) Communication protocol and control strategy matching
Modern new energy vehicles usually require the motor controller to communicate with the entire VCU.
Therefore, suppliers need to support:
· CAN communication protocol;
· Control parameter calibration;
· Fault information feedback;
· Vehicle control logic matching.
(4) Installation environment adaptation
Different vehicle application environments have different requirements for product structure design, such as:
· Protection level requirements;
· Cooling method;
· Installation size;
· Anti-vibration and shock resistance capability.
Only when the electric drive product and the entire vehicle achieve a deep-level match can the vehicle operate stably and reliably for a long time.
What WISE can provide:
Based on the customer's vehicle model requirements and actual application scenarios, we can offer compatible electric drive solutions.
From motor selection, electric control matching, to control parameter adjustment and application optimization, we can help customers reduce the difficulty of system matching and accelerate the vehicle development process.
2. Quality Certification System and Reliability Verification
For electric vehicles, the quality of the power system is directly related to the safety of the entire vehicle and the brand reputation. Especially for suppliers whose products are exported to overseas markets, in addition to providing products with stable performance, they also need to meet the system certifications required by different countries and regions.
During the procurement process, the following aspects need to be paid attention to:
(1) Supplier Quality Management System
Excellent electric drive suppliers usually need to have a complete automotive industry quality management system, such as:
IATF 16949 automotive industry quality management system;
Product development process management system.
These systems can ensure that the supplier controls the quality throughout the entire process from research and development, production to after-sales service.
(2) Product Reliability Testing
Electric drive products need to undergo various reliability verifications, including:
High and low temperature cycling tests;
Aging tests;
Protection level tests;
Long-term operation tests;
Load capacity tests;
Vibration and shock tests.
By simulating the actual usage environment, the stability of the product in complex conditions is verified.
(3) Overseas Market Certification Capability
For different export markets, suppliers need to provide corresponding certification certificates, such as:
CE certification;
Certification requirements for other regions.
What WISE can provide:
A well-established quality management system. The products undergo full-process and multi-stage inspections and reliability verifications before leaving the factory.
Currently, we have obtained:
· IATF 16949 quality system certification;
· CE certification;
· Multiple technical patents.
Through strict R&D and production processes, each batch of products has reliable and excellent quality.
3. Customized Development Support for Software and Hardware
For electric drive products, in some specific scenarios, they need to be developed and manufactured in accordance with the requirements of motor vehicle manufacturers.
High-quality suppliers not only need to have the ability to produce products, but also need to possess the capabilities of product research and design. For new energy vehicle manufacturers, standardized power products often fail to fully meet the application requirements of different vehicle models. Therefore, more and more enterprises are beginning to seek partners that can provide customized powertrain of electric vehicle solutions. They conduct targeted development based on vehicle type, operating environment, and performance targets.
When purchasing, it is necessary to pay attention to whether the supplier supports:
(1) Hardware customization
Including:
Equipment structure adjustment;
Installation size optimization;
Power level adjustment;
Connection method adjustment;
Protection design optimization.
(2) Software customization
The software development capability of the motor controller has a significant impact on the overall performance of the vehicle. Therefore, when the purchaser selects professional EV motor controller manufacturers for electric vehicles, they need to carefully examine whether the supplier possesses the capabilities of control strategy development, communication protocol matching, and parameter optimization.
Including:
Control parameter adjustment;
Torque output strategy optimization;
Acceleration response adjustment;
Fault protection logic optimization;
CAN communication protocol adaptation.
(3) Joint R&D capabilities
For new project development, suppliers need to be able to participate in the early technical exchanges and jointly complete:
Requirement analysis;
Solution design;
Prototype development;
Test verification.
What WISE can provide: In addition to offering standardized electric drive products, it also supports customers in customized development. Based on the specific requirements of the customers and the application needs of different vehicle models, it can provide parameter optimization, supporting solution design, and electric drive system development services.
