Faster Car Charging From Delta & YHI
With the number of plug-in electric vehicles growing across New Zealand. YHI Power Systems are now able to support this with the latest charger units from Delta. Offering user-friendly DC quick chargers as well as AC chargers, Taiwan-based Delta Group has utilised its 40 years expertise in power conversion and management technologies to provide energy-efficient and smart-grid-capable electric vehicle (EV) charging solutions that include not just efficient charger units but also a charger site management system with a web-based interface for easy remote setup, management, and maintenance.
YHI Power Systems manager, Dean Jorgensen, says installing the Delta AC EV chargers is as easy as wiring in any other appliance or fitting and electricians should take the opportunity to get involved with this new area of work.
“The smaller AC charger is a smart interface device providing power to an EV’s on-board charger, but it is still just an appliance for wiring purposes and any electrician can install it. All you have to do is wire it with suitably sized cabling similar size to a stove circuit and treat it like a standard power connection from the MCB to the AC charger.”
YHI’s senior sales engineer, Aaron Gillon, says Delta has made it easy for the electrical industry to embrace the charging of electric vehicles with units that can handle single cars as well as fleets and multiple users.
“The Delta EV AC Charger is a 240 V, 30 amp unit that will fully charge an EV in three hours if there is a 28 amp charger in the car. This makes it ideal for the many new and used EVs now coming into the country.
“It can provide much more power than the 10 amp charger bundled with vehicles and its operation is absolutely safe. The Delta EV AC Charger automatically checks the car’s system to ensure a safe transfer of power. The chance of arcing is eliminated and there are a lot of protective functions such as an inbuilt RCD.”
Advanced features include a delay timer for off-peak charging, an RFID card reader and wired and wireless network communication capability. The back-office integration takes care of user authentication and provides value-adding service options, making the AC unit suitable for both residential and commercial applications.
Where clients want the fastest possible charging times for people on the move, the Delta EV DC Quick Charger will charge a vehicle in 15 to 30 minutes depending primarily on the car battery size.
Designed for highway and service station installations as well as busy commercial fleets, the Quick Charger is a CHAdeMO standard certified charger with a high power conversion efficiency of 94 percent.
It has a large 12" LCD display, user authentication card reader, as well as multiple communication options.
Gillon says the Quick Charger communicates directly with the EV batteries and confirms its status, checking temperature and remaining charge.
“There are a lot measurement and control functions to prepare for the high current and ensure a safe, complete and rapid charge and to monitor the power transfer through the charging process.”
He says EVs designed to the Japanese (CHAdeMO) standard or the European (SAE DC) standard are both catered for with lead sets for each optionally available.
Dean Jorgensen says with plug-in electric vehicles becoming increasingly accepted in New Zealand, the electrical industry can have a lot of confidence in Delta as a supplier of charging systems.
“Delta has built a leading position in EV charging technology with a large installed base in the States, Europe and Asia, and also as a leading OEM to other major brands.”
He says the Delta AC and DC charger units offer more features and are the best value option for EV users and commercial operators. Practical advantages such as long five-metre leads that allow parking flexibility add to their usability.
YHI Power Systems began supplying Delta chargers late last year, adding to its growing power quality services. The company offers experienced engineering advice and solutions for uninterrupted power supply and power protection, DC power systems, energy management, batteries and solar power installations.
“We are at the forefront of renewable energy efficiency and are here to help any company wanting to add electric vehicle charging services to their business.”
