As from next year, car manufactures are to fit out its vehicles with wireless charging technology. Under tha name “Qi”, this term stands for the worldwide standard for the wireless charging based on the physical principle of electromagnetic induction. For the purposes of wireless charging, the Qi-compatible vehicle requires to be placed in the vicinity of the Qi charging station, charging then begins automatically. When the battery is full or the device is removed, the charging process is discontinued automatically.
Saving the environment can be exhausting, especially if you own an electric vehicle that requires you to physically plug and unplug the charger into and out of the charging port. Fortunately, wireless charging for your electric or plug-in hybrid vehicle is all but certain to become ubiquitous, and the automotive-engineering is currently working on creating a standard for these charging systems.
Electrified powertrains, specifically Battery Electric and Plug-In Electric (BEV/ PHEV) vehicles are projected internationally to become more prevalent in production due to environmental factors (such as CO2 emissions), regulations (such as the Greenhouse Gas and the California ZEV Mandate) and the increasing price of fossil fuels. The main benefits of electrified powertrains are eliminating or significantly reducing local emissions while increasing the overall well-to-wheels efficiency.
Standardized Wireless Power Transfer (WPT) through wireless charging provides the customer an automated and more convenient and alternative to plug-in (conductive) charging. Essentially the customer simply needs to park into a compatible parking space in order to charge the vehicle.
SEETECH can provide equipment for testing the common frequency band of 85 kHz (81.39–90.00 kHz). 4 Classes of wireless power transfer levels that result in slower or faster charge times: 3.7 kW, 7.7 kW, 11.0 kW, and 22.0 kW. Quicker power transfer levels may be added in future.
Our equipment’s can test:
- Correct operation of the charging stations and show output frequency and power transfer level.
- Correct charging operation from the car module.
- Read battery levels.
- Estimate charging time and detect issues.
Some vehicles that will have this technology is the new Audi Q7 e-Tron; also BMW and Mercedes-Benz are Working on Wireless Charging Systems
Consumers will be able to charge their electric vehicles wirelessly at any number of locations without worrying that a specific wireless charging station won’t be compatible with their car or truck. Although the standard has been written to create a norm for stationary wireless charging systems, looking toward the future that it is open to wireless charging systems that work while the vehicle is in motion.
Don’t hesitate to contact SEETECH to know what we can provide for your company needs to audit or test wireless charging.
