BYD unveiled last week several technologies to improve fuel efficiencies by more than 20 percent in all its 2014 vehicle line-up.
The company is calling it the “Green Hybrid.”
There are several breakthroughs said to be tied to the “Green Hybrid” initiative; first 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, 12-volt DC Lead-Acid technologies).
BYD said 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.
48-volt DC systems are not hindered by the line/harness power losses experienced with normal lower-voltage systems (saving important energy for batteries). BYD then implemented low-voltage, large-torque, double-winding motor technologies for battery-acceleration-assist and regenerative braking.
BYD said these changes have been shown to save as much as 1.5 liters of fuel per100 kilometers (on a 30 mpg car, that’s as much as a 7 mpg improvement).
Two models of the Qin concept car were on display at the Auto show though the Qin officially launches in mass-production later this year in China.
Qin is the next-generation dual-mode electric vehicle flagship vehicle using BYD’s Dual Mode II system.
The Qin can travel 50 kilometers (31 miles) on a single 10 kilowatt-hour charge and in hybrid mode provides 223 kilowatt of power. This allows for acceleration to 100 kilometer per hour (62 mph) in 5.9 seconds (this was previously advertised as 6.9 sec, but BYD has improved it over the last year).
The Qin also has a top speed of 185 kilometer per hour (115 mph).
BYD said in hybrid mode, the Qin requires just 16 RMB (~$2.50 USD) of energy per 100 kilometers (equating to a little less than 2 liters of fuel per 100 kilometers or 118 mpg).
