CEC Ruihua held in Changchun

On September 18, 2014, China Electronics Ruihua Electronic Technology Co., Ltd. (hereinafter referred to as CEC Ruihua) held the "NL Bipolar Power Symposium" at Changchun FAW Technology Center. The electrical engineers, test engineers, and project managers from the Changchun New Energy Automotive Drive Assembly design and manufacturing field gathered to discuss new concepts and new technologies for power battery testing. They shared the success of the power test using NL bipolar power supply with experts. Case.

This seminar focused on the testing problems encountered by the German Hoecherl & Hackl company in the development of electric vehicle battery powered personnel. The NL Source-Sinks series is a four-quadrant power supply designed for laboratory and production and quality inspection. As a linear modulation bipolar power supply, the bipolar power supply absorbs voltage/current sources and currents. The device (load) is integrated into a device that can cover ±50V (bipolar) voltage range, 100V (unipolar), current up to 320A, power from 100W to 3,250W, and more power Custom products. The NL Series bipolar power supply is suitable for a variety of test applications, such as: EV battery and super capacitor modules, battery battery management (BMS) characteristics of the simulation test, test storage device, generator, solar panels, electrical drive Systems, battery chargers, power supplies, and electrical components; equally suitable for load simulation, dynamic testing, life testing, and battery simulation.

At the same time, the choices of the software tools included by the CLP Ruihua engineers include: charging and discharging simulations of electric vehicles' power batteries and simulation of operating conditions, real-time recording of charging and discharging curves, and analysis of curve data.

Experts from Hoecherl & Hackl demonstrate the excellent dynamic characteristics and high-speed polarity switching of the NL Series bipolar power supplies. The NL series chassis is rugged and reliable. It can be mounted on a standard 19” industrial rack and can be used on the desk. Its superior features can meet the future test requirements of power supply test engineers.
