Developments in e-mobility present new challenges for vehicle and charging-system manufacturers. Due to high availability of the 230 V AC main power supply, conductive charging systems for electric vehicles are now widespread. The relatively new standards IEC 61851-1, DIN 70121, ISO 15118 and SAE J1772 describe the requirements for European and US AC- and DC-charging-systems, electrical waveforms and the pilot signal to control the charging process. By combining electric vehicles and charging systems from various manufacturers, different system-tolerances and disturbing influences may occur. The causes of charge interruptions are very difficult to locate due to the long charging period.

Air-conditioning equipment refers to a device used to create and maintain fixed temperature, relative humidity, and air movement & purity conditions in indoor spaces. Balanced room-type calorimeter and Indoor air enthalpy are the two major methods to test the air-conditioner. Based on the Air-conditioning equipment type, there are different standards such as ISO 5151, ISO 13253, ISO 15042, GB/T 7725, GB 21455, ARI-310/380, JIS B 8515 & JIS C 9612.
According to the ISO 5151, the air conditioning system needs to be tested at 90% and 110% of the rated voltage input during the maximum operating cooling/heating test. If the air conditioning system has more than one input voltage, test according to 90% and 110% of the nameplate voltage. If the DUT has different input rated frequencies, they must also be tested. ONsys Provides Stable Power Solutions for Diverse Testing Needs ONsys programmable AC power source lineups, we offer a wide selection for different test applications. These power sources offer an adjustable voltage output range of 0-310Vac and support a wide range of frequency outputs, with capabilities extending up to 2000Hz, which is well-suited for simulating test standards such as ISO 5151, GB/T 7725, and GB 21455. With a power range spanning from 600VA to 2000kVA, they are suitable not only for testing room air conditioners but also for packaged air conditioner testing.
Nowadays, mainstream EV structures include 400-volt systems and 800-volt systems. 800-volt systems used less current with smaller and lighter cables and wires, cutting down the circuit resistance, leading to enhanced power density and energy efficiency, making the battery charge faster. When the voltage increases and maintains a certain charging current, it helps to increase the charging energy (power), as the result, reduced the charging time.According to IEC 61851-23, the peak of the charging station is 1000V, and can charge at 250kW. However, the vast majority of EVs are 400-volt systems, in which the charging voltage can only be less than 500V. Also, charging time and split charging are likely to be the factors that cause charging stations unable to reach the highest charging power; only shifting the 400-volt system to 800 volts can improve the charging efficiency and lower charging time. It aims to cover different types of OBC to simulate multiple international test standards, including GB/T 18487.1-2015, QC/T 895-2011, IEC 61851-1:2001. They can also complete OBC testing which includes power line disturbance and reliability testing. ONsys has complete AC and DC programmable power source and testing system solutions that especially focus on the growing EV market. The key components including OBC, Motor inverter, High Voltage motor, HVAC compressor.
