2016 BYD Tang: Plug-In Hybrid SUV Is First Of Four To Come

It's been more than six years since fabled investor Warren Buffet bought 10 percent of BYD Autos, one of the few independent Chinese automakers.
At that time, the company had big plans to become China's largest producer of plug-in electric vehicles--and then export them to the U.S.

While the Chinese market for plug-ins has developed more slowly than expected, BYD has persevered with a new range of plug-in hybrids.
It has been selling its compact Qin plug-in hybrid sedan for a year, and is now taking orders for its second model, the Tang plug-in hybrid compact SUV.
The BYD Tang retails for about 300,000 yuan (roughly $48,000 at today's exchange rate).

And, according to a report by Bloomberg, more plug-in hybrid SUV models are on the way--including two this year alone, to be named after China's revered Song and Yuan dynasties.
A further SUV, the Ming, will follow at a later date, according to a presentation given by the company last week.
BYD was the first company in the world to launch a production plug-in hybrid; its F3DM in 2008 was two years ahead of the 2011 Chevrolet Volt.

Do not kill your battery! Electronic products Battery cold literacy

Today's electronic products no longer use the 5th battery to be replaced, the charge is brought more convenience and more serious cell phone addiction, but the correct way to use your battery it? The following article will reveal the dark side of your battery.

cold knowledge: new phone's battery charge in the end should be how long?
I am sure you have heard of such a legend: the first time to buy a new phone on charge must be charged 10 hours, so as to be expanded to the maximum capacity of the battery, the battery will be durable. Is it true?
Generally speaking, this view is held by parents' generation of people, that's them, a lot of old electronic products using a nickel-cadmium batterythat is characterized by "memory effect", that no long-term complete charge and discharge will allow the battery to leave a "habit" lead to a decline in the efficiency of the battery.
But today's electronic products already do not use nickel-cadmium type batteries, but all replaced by a lithium battery, lithium batteries, however, and no so-called "memory effect", with electronic products are now after the device is fully charged automatically cut off the power supply, So you dash for longer does not make sense.
So the answer to this question is that the new phone or, old phone or, full, please unplug it.
 cold knowledge II: battery run out before charging must take it?
Many people are used to the electronic products before charging the battery completely run out, in the off state began to charge, in fact, this is influenced by the nickel-cadmium battery memory effect.
For lithium batteries, there is another phenomenon called cell activity:a new lithium battery and can not play all the utility you want to use for some time after most of the lithium-ion activated in order to achieve the best results, and thorough discharge is the biggest killer inhibitory activity.
In general, the best power electronics products is 20% to 90%, so the phone at around 20% power to trouble charging it.
 cold knowledge Three: You can use the phone while charging it?
The problem is the party most likely to encounter a lot of phones, because the lack of electricity, often connected to the power supply after continued use, but it actually is a very dangerous move.
In playing the game, call these processes, the phone will have a serious fever, while charging the phone will also promote fever, when both simultaneously, it may cause the battery to overheat explosion, the explosion occurred once, maybe you would never the opportunity to use a mobile phone.
Although there are some very small daily problems, but if you pay attention, it will greatly shorten the battery life, which is why someone with a cell phone can also spend one day a year, six months before you have your cell phone hanging spank bottles.
Love is not only a mobile phone handset battery charge is responsible for your own life, oh.

Do you know the real reason for the lithium battery performance degradation it?

Li-ion battery has now been widely used in mobile devices, but the battery life is not long, 500 charging cycles will lose about 1/5 of capacity. In order to study the reasons for the lithium battery degradation, the US Pacific Northwest National Laboratory scientist using a powerful microscope to observe the success of the real-time status of the lithium battery charge and discharge.

The researchers found that when using the battery creates pressure and cause rupture electrode. In addition, for each charge and discharge cycle will leave traces of lithium electrode in addition to these "death" of lithium which can no longer play a role in the future of charging, and will cause a decline in battery capacity. The researchers also observed in the solid electrolyte interphase layer is formed on the electrode surface, which can "clog" the battery and affect its ability to charge.
Lithium who want to solve these problems, the use of alternative methods is one of the elements. In the future, magnesium, aluminum, or copper and other metals could become cheaper and stable alternative, however, the performance of these batteries is still not up to the level of lithium batteries.

Battery Tests Show Some Lithium-Ion Cells Last Over 5x Longer

Researcher Andreas Gutsch from the Karlsruhe Institute of Technology said at the PV Symposium in Germany recently that some lithium-ion cells working in storage systems experienced up to 30% capacity loss after 1,000 cycles, while some cells have a better capacity after 5,000 cycles. In other words, there can be quite a lot of variation in lithium-ion cell performance.


Testing conditions did not allow him to reveal the names of cell manufacturers. The cells were not easy to obtain for testing and he could not disclose that specific information. However, his test results did reveal that cells from China that were tested had the performance that decreased most rapidly. Cells from Japan and Germany did the best, while ones from South Korea and the US were in the middle of the performance range.

One battery type that was specifically mentioned was the Tesla battery. This battery was found to last 400 cycles and was indicated to have the ability to power a car for about 200,000 kilometers (124,000 miles): 400 cycles multiplied by 500 km per full charge. That said, Elon Musk has stated that Tesla has a Model S in the lab with 500,000 miles (805,000 kilometers) on it, and without excess degradation. So, it seems the tests have been conducted very differently or something funky is going on.

Gutsch previously noted that some energy storage battery types might have safety issues, such as thermal runaway. According to his research, safety standards for some batteries have not been met.

He does believe batteries will eventually be a great way to store electricity, though.

All, or most of us lay people are on a learning curve when it comes considering how to evaluate the best batteries for consumer technology performance. To engineers, it may not be surprising at all that there could be such a range in cell performance. It may be fairly dismaying to lay persons to find this out, though we may notice that some of our consumer devices (like smartphones and other rechargeables) have poor to very poor battery lives, with variation being rather large.

Battery storage for a home or business is quite another matter.


China's BYD ramps up 'leccycar battery production in challenge to Tesla

Warren Buffett-backed Chinese car manufacturer BYD is aiming to compete with Tesla Motors by tripling its production of batteries for electric cars over the next three years.

BYD will produce an additional six gigawatt-hours' worth of batteries per year over the next three years, said company spokesperson Matthew Jurjevich, adding that with the support of consumer demand these production increases could be continued beyond the three years of increase scheduled.

If this rate of production increase continues to 2020, BYD would be set up to challenge Tesla Motors' $5bn Gigafactory in Nevada, which is projected to achieve an annual production capacity of 35GWh when it begins operating in 2016.

Rumours of difficulties in the development of the Tesla Gigafactory have been refuted by CEO Elon Musk. The company is, however, downsizing its Chinese operations following a bungled incursion into the market which has left its distribution centres overstocked. Tesla does not currently produce battery cells, instead sourcing them from Panasonic.

Reuters cites GTM Research as estimating the electricity storage sector growing from a $128m market in 2014 to being worth $1.5bn in the US alone by 2019.

While BYD electric cars aren't luxury models like Tesla's, BYD may be at an advantage in regularly utilising Lithium Ferrophosphate (LiFePO4) batteries in their Energy Storage Systems. LiFePO4 is a Li-ion battery technology which offers a considerably longer cycle-life than the batteries Tesla uses.

In 2010, BYD came first in Bloomberg Businessweek's Top 100. Businessweek claimed that Warren Buffett, though “legendary for his dislike of tech investments”, was persuaded by Charlie Munger “to buy a 10 per cent stake in BYD for about $230m. That was in September 2008. Today Buffett's piece is worth nearly $2bn.”

BYD recently partnered with Uber, who are running 25 of BYD's e6 models around Chicago as part of a ride-sharing venture with Green Wheels.

About the past era of lithium aluminum battery age will come up?

Chinese American scientists have developed a high-performance aluminum battery's first commercial application, its charge faster, last longer and very cheap, just one minute using this smart phone battery is fully charged. The new battery can replace the widely used but there is still insufficient lithium ion batteries and alkaline batteries. Research published in the April 6 issue of "Nature" magazine online edition.

Because aluminum battery has a low cost, easy to burn and do not have a high charge storage capacity, etc., for decades researchers have attempted to develop an economically viable to aluminum ion batteries, but has not been successful, where the key challenge is to find the right positive materials and electrolyte materials, so that the aluminum battery is constantly charging and discharging cycles can still produce an effective voltage.

The study's lead author, professor of chemistry at Stanford University Dai said: "People try a variety of cathode materials, but the effect is unsatisfactory we accidentally discovered a new graphite material, which has excellent performance, can be used as a positive electrode of the battery. "

According to the US Science Daily website reported April 6, and the cathode is comprised of graphite researchers in experiments by aluminum anode, coupled with the ionic liquid electrolyte, placed in a flexible polymer foil-wrapped software package in the manufacture of this battery. The research collaborators Gong Ming (phonetic) said: "The electrolyte is basically a liquid salt at room temperature state, therefore, the entire system is very safe."

Dai Hongjie said: "The newly developed aluminum rechargeable batteries safer than conventional lithium-ion batteries, lithium ion batteries may explode, in order to take preventive measures, United Airlines and Delta Air Lines recently forbid civil aircraft checked chunks Lithium batteries, aluminum battery will not explode. On the other hand, is currently equipped with a lithium-ion battery charging smartphones may take several hours, but the use of this aluminum battery for a fully charged cell phone just a minute. "

Aluminum ion battery developed at the University of domestic mobile phone charger available one hour four days

In addition, the new battery life is very long. Other laboratory developed aluminum battery can charge and discharge 100 times, usually lithium-ion battery charge and discharge up to only 1000, and the new aluminum battery without any loss in capacity after 7500 charge-discharge cycles later. The researchers said, "This is the first time the development of this fast, and after thousands of charge-discharge cycles 'torture' still safe and sound after the aluminum ion batteries."

Dai Hongjie said that another feature of the new battery is its soft figure, you can also make it bent its folded, therefore, has the potential for flexible electronic devices. In addition, the battery can replace alkaline batteries will pollute the environment, but also cheaper than aluminum lithium battery. "In addition to small electronic devices, such aluminum battery can be used for renewable energy storage within the grid Dai Hongjie explained:." Grid requires a long life and can quickly charge and discharge the battery, our aluminum battery is the perfect choice . "

However, the voltage of the battery to produce new aluminum lithium battery is only half of the traditional, Dai Hongjie hope can improve the performance of the cathode material, and ultimately improve the aluminum battery voltage and increase the energy density. .

Power lithium battery high demand in 2014 will meet the explosive growth of the future

ufo battery offical site
2014, the number of new cars in the global energy yield sales USA, China, Japan, the European Union and other countries and regions, led by more than 300,000, only China's new energy vehicle production in 2014 reached 83,900. The rapid development of new energy automotive industry, so that the global growth in demand for lithium battery power significantly. According to statistics, in 2014 the world's lithium-ion battery shipments reached 10012.8MWH.
Recalling 2014, AESC, BYD and LG lithium battery shipments over 1GWH, to become the world's top three manufacturers of lithium battery. In 2014, about 800MWH Panasonic lithium battery shipments, SDI, LEJ, Hefei, China Xuan and other enterprises Air lithium lithium battery shipments ranking. AESC batteries which are mainly supplied to the Nissan LEAF and the Renault Kangoo ZE, 24AH batteries using NCM ternary system; LG major supplier to the Chevrolet Volt, Renault ZOE, Volvo V 60 Plug-in other models, the use of the ternary system battery; Panasonic major supplier to the Toyota Prius Plug-in, Ford Fusion Energi, Ford C-Max Energi, Volkswagen e-up and other models; the main supply models SDI for BMW I3 and I8 other models, LEJ Mitsubishi I-miev, Mitsubishi Outlander PHEV and other battery powered vehicles.

Our power lithium battery manufacturers mainly concentrated in Guangdong, Shandong, Jiangsu, Zhejiang, Tianjin and other places, the Chinese enterprises in 2014 the basic use of lithium iron phosphate batteries. 2015 began, there have been a number of domestic models such as EV200, Zotye cloud 100, the second generation of BMW's promise, JAC began using ternary battery batteries. There are rumors that a number of domestic car companies are working with Panasonic negotiations, the intentional introduction of its 18650 NCA batteries fitted to their new energy vehicles. So you can see, the future of the ternary material will become the main power lithium battery cathode material. Currently the major battery plant is actively preparing, and expand the sources of procurement of raw materials, for laying the foundation for the upcoming expansion wave.
Ministry data show that two months of 2015, China produced a total of about 12,000 new energy vehicles. Market analysts said that with all levels of government continue to overweight new energy automotive industry policy, this year China's new energy vehicle population is expected to exceed 20 million units, and as a core component of the electric vehicle battery market demand will be explosive, lithium ion battery market officially entered the golden period.
Relevant institutions predict that by 2020, car ownership in China will reach 200 million, according to the new energy vehicles accounted for 2% of the total vehicle computing, when China's new energy vehicle ownership will reach as many as 4 million. According to the estimated growth curve in 2020, China's annual production of new energy vehicles will be about 1 million. According to a conservative car loaded 30kwh battery, the annual consumption of battery power will reach 30 million kwh, the annual consumption of about 50,000 tons cathode material, anode material about 2.5 million tons, about 28,000 tons of electrolyte, separator of about 400 million square meters. At the current yield calculated on battery power, 2020 will be the expansion of our battery 8x power lithium battery industry will usher in the explosive growth and related industries to flourish.
