ANPA1000 Power Analyzer Facilitates Efficient Testing of Drive Motors

I. Industry Background

The rapid development of the new energy vehicle industry has driven the growth of the supporting drive motor market. In 2023, China's drive motor installations reached 8.17 million units, an increase of 41.3% year-on-year. It is expected that China's drive motor installations will reach 11.57 million units by 2025, with a compound growth rate of about 24.2%.

II. Application Demands

With the rapid development of new energy drive motor technology, market demands for its performance and safety are increasingly higher. The state and relevant departments have successively formulated a series of standards and regulations, which put forward requirements for vehicle manufacturers and third-party supporting manufacturers in the (research and development) R&D and production process of drive motors, in order to ensure that the product indicators meet the safety and quality requirements.

1. National standards

GB/T 43254-2023：Functional safety requirements and testing methods for drive motor system for electric vehicles

GB/T 29307-2022：Reliability test methods of drive motor system for electric vehicles

GB/T 36282-2018：Electromagnetic compatibility requirements and test methods of drive motor system for electric vehicles

GB/T 18488.1-2015：Drive motor system for electric vehicles—Part 1: Specification

GB/T 18488.2-2015：Drive motor system for electric vehicles—Part 2: Test methods

2. Testing requirements

As a core component of the electric vehicle's battery system, electric drive system, and electronic control system, the performance of the drive motor directly affects the energy efficiency, driving range, and reliability of the entire vehicle. Manufacturers need to measure many parameters in the R&D and production process of drive motors and entire vehicles, including the voltage, current, electrical power, torque, speed, electric drive system efficiency, and overall system efficiency of the drive motor, in order to simulate the road cycle test conditions of an entire vehicle, thereby shortening the development and testing cycle and reducing the development and testing risks and costs.
