BYD e6 taxis in China – Click above for high-res image gallery

A year has passed since BYD pressed a 50-strong troop of all-electric e6 crossovers into service with the Pengcheng Electric Taxi Company. To mark the occasion, the automaker is happy to report that the rapid-charging regimen the cars are using has not impacted the performance of their lithium iron phosphate (LiFePO4) battery packs.

According to the Buffet-backed company, the taxi batteries were regularly rapid-charged for 20 to 30 minutes and, after a cumulative 1,730,000 miles, the fleet vehicles experienced no noticeable range or performance degredation. Through a hot Shenzhen summer and very cold winter, Senior Vice President Stella Li reports "...drivers and passengers alike have been extremely satisfied with their ride experience." It did seem nice enough when we rode along, under very different conditions.

BYD also released information about its ongoing trials of the F3DM hybrid in Los Angeles and eBus-12 program in China. Apparently the hybrids have traveled a total of 14,430 miles, of which only 4,000 required the burning of gasoline. BYD calculates the cars achieved the equivalent of 88 miles per gallon.

The buses have successfully trundled along for 28,802 miles since their introduction in January and estimate the people carriers have saved $2833 monthly in fuel costs. BYD expects to deliver 300 more buses, as well as 250 more taxis, this August. Hit the jump for more details from the official press release.

BYD Announces EV Fleet Results at Anniversary of Green-Taxi Project

SHENZHEN, PRC – Today is the one year anniversary of the world's largest all-electric vehicle Taxi fleet supplied by BYD. In conjunction with this anniversary, BYD announced results of several of its electric vehicle pilots – the F3DM, e6 and eBUS-12 fleet testing across the world. Fifty (50) of the BYD's e6, five(5)-seat crossover vehicles, each with a range of over 160 miles (250-300 Km) and a top speed of 88 mph (or 140km/h) have been in service at Shenzhen-based Pengcheng Electric Taxi Company since April 29, 2010. The Shenzhen e6 Taxi fleet has now accumulated ~1,730,000 all-electric miles (or 2.77 million kilometers) while being rapid charged in 20-30 minutes. The distance traveled for single fleet vehicles has reached ~63,000 miles each (or 100,000 km). "This fleet of 50 e6 taxis has survived the very harsh operating conditions of hot Shenzhen summers and a very cold winter this year, and drivers and passengers alike have been extremely satisfied with their ride experience", according to Stella Li, Senior Vice President. 250 more eTaxi's are being delivered to the International University in Shenzhen before August this year and officials believe that the per-car-fuel-savings is over $1167 per-Taxi-per-month or
7519RMB per-car-per-month (driving an average of 400Km per day). BYD's all-electric Taxis are expected to help Shenzhen avoid about 133 lbs (or 60.4Kg) of carbon-dioxide pollution per day per Taxi. This is an equivalent of 2,425,060 lbs (or 1.1M kg) of carbon-dioxide pollution avoided by this fleet in this first year.

The most important finding in the e6 fleet testing was that there has been no noticeable energy drop – both driving range and battery performance has been stable in rapid-charging conditions over the 1.73M miles tested – a breakthrough in EV rapid-charging. BYD has been challenged by the media about its claims of long-range electric vehicles and superior battery longevity in rapid-charging regimes, ever since it launched its first dual-mode, electric and plug-in-hybrid electric vehicles in December 2008. BYD now feels that it has proven its Iron-Phosphate battery technology with fleet test results and can discuss on-going vehicle charging efficiencies, consumption efficiencies, EV ranges over time and with rapid-charging regimes.

BYD further reported on its F3DM fleet which BYD launched in its first US tests at the Housing Authority of Los Angeles (HACLA). The F3DM can travel over 40 miles (or 60 Km) all-electric but can be engaged to act as a Hybrid-Electric (HEV) to extend its range up to 300 miles. HACLA fleets have now accumulated ~10,430 miles all-electric and 14,430 total miles (4,000 fuel-driven miles when extended range was necessary). The fleet is achieving an equivalent of 88 mpg and BYD believes that the per-car-savings (even netting out EV charging and electricity costs) is ~70%. BYD's dual-mode cars are expected to save HACLA about 37 lbs (or 16.8 Kg) of carbon-dioxide per-day-per-F3DM when driven to the EV range.

BYD launched a Chinese approved all-electric bus fleet with the eBUS-12 (click for video link) in Shenzhen and Changsha China January 2011. These fleets have already accumulated 28,802 all-electric miles (or 46,380 Km) while undergoing a 3-hour-charge of the 324 Kwh FE battery. An example of the per-eBUS-savings for Shenzhen's Bus Line 202 (driving only 200Km per day) is about $2833 monthly per eBUS (or 18417 RMB per month). 300 more buses will be delivered to Shenzhen in August of this year. BYD's all-electric eBUSes avoid about 708 lbs (or 322Kg) in carbon-dioxide per eBUS per day.

In total, BYD EVs have accumulated over 1.769 million all-electric miles and have seen no diminished range or capacity due to the rapid-charging. BYD vehicles are estimated to have already saved $360,000 in fuel costs and over 2.776 million lbs of carbon-dioxide. BYD launched consumer sales of the F3DM September 27th, 2010 and anticipates very good demand for the BYD e6 and all electric vehicles in China, based on city policy changes in cities like Beijing who announced, "consumers that purchase pure electric vehicles will also enjoy the special privilege of "license-plate-lottery-free, no traffic restrictions
and tax-free exemptions (paid by the government)." (http://english.peopledaily.com.cn/90001/98649/7344880.html)

      I hate to be a skeptic but I did some math. The cumulative miles was stated as 1,730,000. The number of cars in the fleet is 50. Therefore, the average miles on each car is 34,600.
        • 4 Years Ago
        @Smith Jim
        That is 94 miles a day, which pretty much what I would expect from a taxi.

      Notice they don't give the range the BYD e6 taxi's got...on an average none the less? 'Cause they're probably not that impressive overall. I would like ta think they are, but they're probably not.

      ffinder: Why are you writing about Nissan leaf ? those batteries are NOT the same as BYD batteries. BYD batteries are "for the life of the vehicle" (hint: You wont change them, they will hold for 15 years). There are lots of specific data on the batteries in the unofficial byd electric car forum ( http://bydelectriccar.com ) ... Also these are not dangerous batteries ... I don't know about Nissan Leaf batteries, but I would assume that they are using outdated technology).
        • 4 Years Ago
        Why would you automatically assume that the world third largest manufacturer is using 'outdated technology' and BYD would be superior? Why do you assume the 'life of the vehicle' will be 15 years? The forum you want to publicise is little more than a PR exercise by Warren Buffets media machine.

      I'd consider a Leaf/ Volt if I was looking to spend that kind of money. In the U.S., you get a lot of car for the money, and it's very tempting to get something much bigger than one needs on the used car market.

      Finder, Why are you so down on this? They are proving at least one of the fears of EV batteries can be mitigated: quick charging with no damage to battery packs. Do they have to solve world hunger as well to get a positive comment? Talk about your glass half empty kind of comment.

        @EV Jack
        Like you, I hate to sound negative about any real advance in EV technology. But, like most PRC enterprises, BYD has a,...ah... 'different', standard of accurracy! Therefore, it's only fair and proper, that announcements from BYD must be examined more carefully. In common with all new technologies, EV's have attracted a lot of over-optimism, failed enterprises, unrealistic claims, and vapourware scamsters. So now that the first rush of over enthusiasm has settled down and real products are being produced by real manufacturers, EV technology must to be treated in the same way as all technology and the one-eyed passionate approach sholud be abandoned. This alway happens when a passionate cause, settle down to become mainstream business.

      Even with installations of 30 minute DC fast chargers all over the US the no. 1 problem is not solved. The cost of the battery. The battery cost of the Leaf is $18,000 giving it the total price of ~$33,000. As long as electric cars cost more than $15,000 (Volt, Leaf) ) will only be bought by 1-2% of car drivers worldwide over 10 years. That's the case with the Prius, in 13 years, it captured less than 2% of the worldwide car market even though they are only $4,000 more expensive than gasoline cars. http://www.euractiv.com/en/innovation/better-place-ceo-biggest-obstacle-electric-cars-auto-industry-interview-500451 Better Place will be selling electric cars cheaper than $15,000 and with an unlimited driving range. Fast forward to 24 minutes 50 seconds: http://www.youtube.com/watch?v=Hk-aVB7LgFI They have already sold 70,000 electric cars one year before launch. The network goes live in 8 months (Israel, Denmark) China jumped in with 2300 battery switch station until 2015 and locally made battery switching EV's just 2 days ago. http://en.wikipedia.org/wiki/Better_Place#China ff

        How does Better Place reduce the cost of the battery? Their costs are HIGHER, they not only have to pay for the battery in your car, but also the spare batteries on their shelves, and their swap stations, and electricity, and make a profit off you. It's as pointless as claiming a leased BMW costs less than buying a BMW. Leasing shifts costs in time, it doesn't reduce them. BYD is not using Better Place's swap technology and has no plans to do so. Only Chery has aligned with BP (and has yet to announce a production car model using it). Now BP is talking to China Southern Grid, which has "built three charging stations in 2010" (i.e. only irrelevant greenwashing and hype so far) and supposedly Guangzhou Automobile Industry Group will make swappable battery cars. Well, maybe. This talk of "China jumped in with 2300 battery switch station until 2015" sounds like garbled translation. Chinese governments and companies have overpromised and underdelivered on EVs for several years now (while going gangbusters on electric bicycles), hence my skepticism.

          Absolutely correct! Better Place, always has these breathless cult followers spamming every website with this pathetic, illogical propaganda. Better Place is a logistically impractical, and the entire business plan is mortally flawed, the only reason is has exists is it was conceived in the first heady days of EV technology, and based on a 1950's magazine article. From the beginning, Better Place has made announcement, after announcement, all either wildly exaggerated or just plain fictitious. Most Better Places employees, (and directors) are bright young guy's with a IT software background. Lot's of money, but very little engineering or capability in logistics, planning or infrastructure design and implementation. Claims like, 'Better Place has already sold 70,000 EV's!' are simply absurd. Nissan/Renault is struggling to manufacture 3000 per month. This is an example of the dissembling methods employed by Better Place. Better Place claims the 100% exclusive support and endorsement of the Australia government for it's Australian scheme. The Australian government did no such thing, what it did say was that if Better Place could obtain all the necessary planning permits and fulfilled all regulatory obligations, The government would have no objection to any environmentally beneficial enterprise. These sort of half truths and outright lies are the only activities Better Place in which Better Place shows any skill.

      It is very promising news, particularly for the full electric cars like Nissan Leaf. We have very interesting findings from Nielsen Energy survey - now most U.S. consumers are ready to buy Electric Cars! We guess that rising gas prices have made all the difference in this change of the sentiment. Cruising Electric Cars on our streets do help as well, Nissan Leafs and GM Volts are getting on the roads and making the best EV marketing possible. Both Electric Cars have scored highest safety ratings in the recent crash tests and it will drive consumer attention as well. http://sufiy.blogspot.com/2011/04/lithium-drive-most-us-consumers-want-to.html

        Sufiy, stop posting links to your blog site, which is nothing more than lithium stock promotion. I guess you have invested in all those companies. Give it a rest.
