At the moment when the new energy vehicle industry is developing rapidly, the entire industry is making every effort to promote innovation and breakthroughs in automotive technology. Key areas such as battery management systems and motor drive systems of new energy vehicles are constantly experiencing technological innovation and upgrades. FUYUAN electronic load products play an indispensable role in the R&D and production testing of new energy vehicles with their excellent performance and diverse functions.
Battery testing
The battery performance of new energy vehicles is directly related to the vehicle’s range, safety and stability. FUYUAN electronic load can simulate the discharge process of batteries under different working conditions. For example, by setting multiple modes such as constant current (CC), constant voltage (CV), and constant power (CP), the current, voltage and power changes of the battery under vehicle start-up, acceleration, steady-speed driving and braking energy recovery can be accurately simulated. Taking the battery management system test as an example, the FUYUAN electronic load can accurately set the discharge current in CC mode to test the discharge efficiency and performance stability of the battery under a specific current. The interface of the FUYUAN electronic load when performing a discharge test on the battery in CC mode is shown. The set current value, real-time voltage and power display can be clearly seen, which is convenient for engineers to monitor the test process. In CV mode, the battery’s capacity retention and voltage change under constant voltage are detected. This helps engineers to gain a deeper understanding of battery characteristics, optimize battery management strategies, and improve the overall performance and service life of the battery.
Motor controller testing
The motor controller is one of the core components of the power system of new energy vehicles. Its performance determines the operating efficiency and reliability of the motor. The FUYUAN electronic load can simulate the back electromotive force of the motor under different load conditions, and test the response speed and control accuracy of the motor controller under complex working conditions through dynamic current (DC) and dynamic voltage (DV) modes.
In the development of the motor controller of the automobile, the DC mode of the FUYUAN electronic load is used to set different current change slopes and time parameters to simulate the current demand of the motor under frequent start-stop, acceleration and deceleration conditions, and to verify whether the motor controller can respond quickly and accurately to achieve stable control of the motor.
In the dynamic current mode, parameters such as current A, current B, rising slope, and falling slope can be set, which intuitively demonstrates the ability of the FUYUAN electronic load to simulate complex current conditions and provides an effective means for testing motor controllers.
