Greentech Lead Asia: BYD has unveiled Green Hybrid initiative with “Insta-Pure” cabin filtering systems designed to improve fuel efficiencies by greater than 20 percent in all their 2014 vehicle line-up. The technology was unveiled at Shanghai Auto Show.
BYD becomes the first vehicle OEM to implement the higher-efficiency 48VDC vehicle voltage platforms using BYD’s internally developed Iron-Phosphate batteries versus older heavy-metal-laden, 12VDC Lead-Acid technologies.
This new technology allows the battery life to be extended to the expected life of the car – no more worrisome starter-battery replacements. Vehicles transition to all-LED lighting, Electronic Parking Systems, Hybrid and regenerative braking, idle start-stop energy management, automatic engine starts, low rolling resistance and advanced aero-dynamic designs.
The 48VDC systems are not hindered by the line/harness power losses experienced with normal lower-voltage systems. BYD then implemented low-voltage, large-torque, double-winding motor technologies for battery-acceleration-assist and regenerative braking. These changes have been shown to save as much as 1.5 litres of fuel/ 100km (on a 30 mpg car, that’s as much as a 7 mpg improvement).
BYD’s “Insta-Pure” cabin filtering technology helps protect drivers and passengers from dangerous city PM2.5 issues (Particulate Matter up to 2.5 micrometers in size), by quickly rotating cabin air, scrubbing and filtering it, all in less than 3-5 minutes. The first production vehicles launching with this advanced cabin purification system are the new BYD S6 Premier models –debuting at this year’s show.
BYD also showcases the “Suri” featuring the break-through “Remote Driving Controller” technology that has been selling an average of 10,000 units per month in the China market, exceeding BYD’s expectations.
Another model, the advanced BYD Dual Mode “Qin” officially launches in mass-production later this year in China. Qin is the next-generation dual-mode electric vehicle “flagship” using BYD’s innovativeDual Mode II system. The Qin can travel 50 km (31 miles) on a single 10 KWh charge and in hybrid mode output 223 KW of power and a whopping 440 Nm of torque — accelerating from zero to 100 km/h in only 5.9 seconds.
