According to the International Energy Agency (IEA) forecast, the global fleet of pure electric vehicles (EVs) and hybrid electric vehicles (HEVs) on roads will reach 250 million by 2030. In 2018, IEA reported only 5.1 million such vehicles worldwide. This represents a dramatic increase, driven by mutually reinforcing technological advances in powertrains, power electronics, battery cells/packs, and charging infrastructure.

As the energy replenishment device for electric vehicles, the charging performance of EV charging stations affects battery pack lifespan and charging time.
DC charging stations deliver direct current to vehicles. They draw grid power (three-phase AC) externally, convert AC to DC through rectification within the station, and transmit DC electricity of specified magnitude and power to vehicle batteries under the coordination of the control center and its components.
Electric vehicle wireless charging technology transmits energy via high-frequency alternating magnetic fields from underground power supply rails to vehicle-mounted energy pickup mechanisms within a certain range above ground. This powers onboard energy storage devices, enabling EVs to carry fewer battery packs while extending range. Energy replenishment becomes safer and more convenient.
Key technical parameters for dynamic wireless power transfer include: power transfer distance,power rating,efficiency,lateral misalignment tolerance of coupling mechanism,and electromagnetic compatibility (EMC).
The ISO 16750 series applies to electrical and electronic systems/components of road vehicles. It describes potential environmental stresses and specifies tests and requirements for specific installation locations on vehicles. Its purpose is to help users systematically define and/or apply an internationally recognized set of environmental conditions, tests, and operational requirements based on the intended equipment operation and actual exposure environments.
During the development of the ISO 16750 series, the following environmental factors affecting vehicles were considered: global geography and climate, vehicle types, vehicle usage environments and operational modes, equipment lifecycle, vehicle supply voltage, and in-vehicle installation locations.
An inverter is a converter that transforms direct current (from batteries or accumulators) into alternating current with either fixed/variable frequency and voltage (typically 220V, 50Hz sine wave). It consists of an inverter bridge, control logic, and filtering circuits.
Electric Vertical Takeoff and Landing (eVTOL) aircraft are electrically powered vehicles capable of vertical takeoff and landing like helicopters, while offering higher energy efficiency, lower noise levels, and reduced emissions. These aircraft are recognized as a critical component of future urban air mobility (UAM), demonstrating significant potential in alleviating ground traffic congestion and enabling rapid intercity or intra-city transportation.
Currently, eVTOL development is in a phase of rapid advancement, involving R&D and experimentation across multiple key technologies including:Battery technology,Motor efficiency,Flight control systems,Safety mechanisms.
Our photovoltaic inverter test system provides a comprehensive solution for evaluating photovoltaic inverters, primarily verifying whether their functions and performance characteristics meet design specifications and relevant standards. The grid simulator and DC power source feature paralleled expansion interfaces, enabling testing of photovoltaic inverters across various power ratings.
Throughout the testing process, the system conducts automated testing according to pre-selected test items, automatically records test data, analyzes results, and generates reports with one click. This achieves truly fully automated testing, significantly improving efficiency while saving time and reducing costs for equipment manufacturers and testing institutions.
