common motorcycle battery operational failure

Posted by on May 18, 2012 No comments

We all know that the loss of electricity is a relatively common motorcycle battery operational failure, most people ignore. But they lead to the direct impact to industrial battery life and security of that risk.
Generally caused by the loss of electricity in the case of driving in urban areas resulting in loss of electricity, traveling shorter distances, starting more frequently, while the traveling time is short.
A direct result of: frequent use of a motorcycle battery to start the engine, motorcycle battery power depletion of more motorcycle charging system in a shorter travel time, you can not complete to the motorcycle battery is fully charged, the application over time, motorcycle batteries will be in a state of loss of electricity.
The loss of electricity led to the hazard of motorcycle batteries:
1, the charging voltage than the battery voltage is much higher charging current charging will be particularly large. Also very easy to damage the regulator rectifier.
2, the battery charge current is too large the biggest hazards is easy to cause the plates active material loss, a great impact on battery life.
The battery charge is the moment to bring convenience to your urgent day-to-day work, more to the use of the battery is good, you can extend the battery life of the motorcycle.

Is it your choice for a car battery?

Posted by on May 16, 2012 No comments

When I am in low mood, I would go shopping to try on many beautiful clothes to let me calm down. If one looks beautiful on me, i will buy it even if it’s  a little expensive. But it’s not good to choose a car battery. Why is that?
As we all know, our car battery just lasts for about five years, if you take good care of it. That’s the problem that we always need to pay more attention to which one is suitable for our car. Just ask you, “Is it your choice for a car battery”, then you will think about some questions to ensure if it is really good.

Samsung Galaxy S III

Posted by on May 14, 2012 No comments


There is “a bit of the learning curve and plenty of finger-tapping as you seek out features,” Dolcourt writes. “Regardless, I do really like Samsung’s effort to deeply integrate the camera with the address book in an effort to make sharing photos even more seamless.” As for the photos themselves, they’re “sharply defined and colorful, with the greens looking a tad over saturated as they tend to do on Samsung’s camera phones,” she adds.

Meanwhile, over at GSM Arena, a team of testers put the Galaxy S III through a series of battery tests. Battery life will be particularly important on the S III, with its 4.8-inch screen and energy-sucking processor. But the “huge” 2100 mAh battery lives up to expectations, GSM Arena testers said: You can talk for 10 hours on the S III without draining the battery, or browse the Web for five hours.

Best of all is video playback time. The Galaxy S III, GSM Arena alleges, “required a minute over 10 hours of continues video playback to drain 90 percent of its battery. This should make the S III a great travel companion on those long flight and train trips.”

And what about the sleek chassis of the Galaxy S III? Well, over at Geek.com, Russell Holly likes what he sees.

In the past, Samsung has been highly criticized for having phones that simply felt cheap. Devices like the Samsung Galaxy Note and Galaxy Nexus have helped put a stop to that, but the new Galaxy S III stops that thought completely,” Holly writes. “The phone feels incredibly solid, and the plastic construction only helps it feel lighter. It seems entirely likely that you would lose this phone in your front pocket, simply because you are unable to feel that it is there while you walk around.”

AGM battery equalizing charge

Posted by on May 14, 2012 No comments

The AGM battery charging points in three ways: a floating charge (float); equalizing charge (charging); recycling charge. This article describes the equilibrium charge (charging) the charging parameters and precautions.

Charging parameters

Charge voltage: 2.30 ~ 2.40V / monomer (25 ° C) (recommended setting of 2.35V / monomer)

Maximum charge current: 0.30C10

Temperature compensation coefficient:-3mV / ° C monomer (25 ℃, the starting point)

Charging voltage range of ± 0.02V / monomer

Exit conditions are charge

The battery quit charging current reference value is generally set for 0.01C10, multiplied by the number of battery pack in parallel.

Note:

Normal float operation can not do this. Encounter one of the following circumstances may be considered balanced charge:

· Discharge capacity of more than 20% of the rated capacity;

Left unused for more than 3 months;

· A single battery float voltage is below 2.18V / monomer;

Continuous float 3 to 6 months or battery pack voltage behind the battery;

· Float more than one year of operation;

· Battery installation and commissioning before put into use after the end of the need for a supplementary charge;

· Battery capacity detection are charging;

· Battery into the charging current reference value is generally set to 0.05C10, multiplied by the number of industrial battery pack in parallel.

Bat’Lib swapping station features for electric scooter

Posted by on May 13, 2012 No comments

electric scooter
DBT CEV, one of the largest electric vehicle charging infrastructure firms in Europe, and Matra, a leading manufacturer of Light Electric Vehicles will introduce today at the Electric Vehicle Symposium (EVS26) press conference a unique solution in e-mobility : the Bat’Lib system, an innovative battery swapping station for e-bikes and e-scooters.

The Bat’Lib station allows a user to exchange an empty battery for a full one in less than 10 seconds rather than waiting a few hours for the empty battery to recharge. This intuitive and simple-to-use system eliminates one of the major barriers to electric vehicle use-recharging time-and is ideally suited for electric bike and scooter commercial fleet owners, tour companies, and vehicle sharing programs. Bat’Lib also enables the development of a variety of new business models for renting or leasing batteries and charging services separately from the vehicle purchase.

The Bat’Lib swapping station features ten battery charging ports and its small footprint minimizes space requirements. One port is always kept open to accept a new empty battery while the remaining ports can simultaneously charge nine batteries. The system can be limited to registered users through an RFID system. Upon arrival, the driver removes the empty battery from the vehicle, swipes the RFID card, and inserts the empty battery into the open port. Upon receiving the empty battery, the Bat’Lib immediately opens the door for one of the fully-charged batteries which is ready for immediate use.

The Matra-designed battery pack is built by Chicago-based AllCell Technologies and utilizes AllCell’s proprietary passive thermal management technology, which increases energy density, enhances safety, and dramatically extends battery cycle life.

The two-wheeler swapping station will support the proliferation of new urban mobility solutions in parallel to the current growing selection of electric and plug-in electric cars in the US. By tailoring new charging infrastructure to urban transportation needs, DBT and Matra have created a practical solution for users looking for an affordable and environmentally-friendly alternative for their transportation needs.

Hervé Borgoltz, President of DBT CEV, states: “After several successful collaborations within the field of innovative EV charging with Matra, we believe that we needed to address all electric mobility needs, not only focusing on charging solutions for the electric car driver but also for users willing to make a difference at the local level with smaller vehicles. Thanks to this joint project with Matra, DBT CEV is able to offer a truly comprehensive portfolio of innovative charging solutions.”

Jacques Bonneville, President of Matra MS, states: “The Light Electric Vehicle Market today is leading the global EV market. Two wheelers will continue to play a major role in solving city congestion in US and European markets for years to come. DBT’s expertise in EV charging and Matra’s advanced batteries and vehicles will allow efficient and affordable mobility solutions for fleets and resorts.”

why new electric car battery can’t go far?

Posted by on May 10, 2012 No comments

Some electric cars consumers find the mileage is short after replacing a new car battery. Buy a new electric vehicle batteries have been tested and there is no problem, then what causes the new battery not to run far? In general the following points:

1, the motor. This will be first thought. Current consumption, such as motor demagnetization.

2, the controller. For example, after a period of time parameter drift, the high cut-off voltage.

3, the mechanical resistance. Such as fetal gas, bearings, brakes and so on.

4, the charger charge enough.

5, the battery itself and the temperature difference.

6 lines. Line problem is a soft failure, the components no problems, the only connection among the resistance, there is resistance there is partial pressure, and the current increases the partial pressure of the greater. The new battery wrenching drop them light. This problem is widespread, it ran far nine out of ten.

The following highlights that line problems caused by resistance.

Resistance generated by site:

1, A grounding plug of the controller and the battery and motor grounding plug: Yes Connector gold-plated silver, generally of copper or copper, poor iron. Over time will oxidize, resulting in contact resistance. Large electrical current passes through fever, severe burn black.

2, the fuse. A bad contact. The folder is not tight, pressure is not real.

3, connected to the main circuit power lock switch.

4, the battery solder joints Weld.

5, the battery cable is too small, or not copper. The line length is not good.

6, to pick the wrong line. Such as the controller fine red wire to the battery.

7, the output of the battery compartment or the contact is bad.

If it is a part of a serious, relatively easy to find, such as burning black. If you have a little problem, it is more difficult to find. Little resistance, built up is not easy to overlook. 1 ohm resistor 5 amps of current will produce a voltage drop of 5V. 36V battery to the motor, where only the 31V voltage.

no limit to eye-popping features in future electric cars

Posted by on May 10, 2012 No comments

There seems to be no limit to eye-popping features in future cars.

Flexible-display technology could add new wrinkles in the form of maps, traffic patterns and ads that are projected on dashboards. GM, meanwhile, is exploring the idea of a Windows app that would let consumers draw, play games, “peek” into other locations around the globe in real time, and share music and messages with other passengers on the road.

While that may entice consumers, it worries folks at the Department of Transportation’s National Highway Traffic Safety Administration (NHTSA), which recently proposed guidelines to reduce driver distraction because of the use of dashboard technologies and integrated electronic devices, including smartphones.

NHTSA Administrator David Strickland says, “We are in close contact with manufacturers, component suppliers, Google, Microsoft and others about this.”

There are potential upsides, too. Automated cars would include technology, such as advanced cruise control and crash-imminent braking, that would minimize risk.

“If we get this right, we could eliminate risk to the road,” Strickland says. NHTSA is also considering guidelines for voice-activated controls.

Privacy is another concern, with so much data floating between cars, consumers and the cloud — and the chief reason the vast majority of data would remain anonymous, Baloga says.

“Security is a big issue,” auto analyst Boyadjis says. “There is a conceivable concern about terrorists hacking into an infrastructure system and intentionally crashing cars. Stolen ID is one thing. A car going 60 mph without brakes is a worry.”

But that would be a rare exception in a futuristic city full of autonomous autos, say experts. Transportation by car would never be safer, they contend.

Raj Rajkumar, who heads Carnegie Mellon’s GM autonomous driving lab, argues that in 15 to 20 years, when driverless vehicles become fixtures on U.S. roads, they will help dramatically reduce accidents, as well as the need for big, steel-framed cars to protect drivers.

“Most, if not all, accidents are because of human error,” he says.

“People get drunk, tired, mad, text,” he says. In the future, “Cars will be smaller and lighter, which means better gas mileage, a healthier environment, less traffic jams — even fewer traffic lights.”

Jim Buczkowski, Ford’s director of electronics research and innovation, says, “Technology is important, but how do you create experiences that make (consumers’) lives better? Futuristic cars could deliver, with the promise of safer roads, improved fuel efficiency and a cleaner environment.”

fix a battery defect

Posted by on May 9, 2012 No comments

A house fire that destroyed a $100,000-plus Fisker Karma near Houston last week does not appear to have been caused by the plug-in hybrid’s lithium-ion battery pack, Fisker Automotive said in a statement on Tuesday.

Local officials and insurance companies are investigating the cause of the May 3 fire, which originated in the garage of a newly built home in Sugar Land, Texas. Two other cars in the garage were also destroyed.

“There are conflicting reports and uncertainty surrounding this particular incident,” Fisker said. “The cause of the fire is not yet known and is being investigated.”

After the fire, the Karma’s battery was intact, suggesting it was not a “contributing factor,” Fisker said. The Karma was not plugged in at the time.

Fisker said it has not ruled out possible fraud or malicious intent. Fire officials and investigators are examining an electrical panel in the garage, Fisker said, adding that it was “aware” of fireworks in the garage.

In recent months, Fisker has fielded tough questions about the reliability of the Karma after a spate of high-profile battery problems. No fires or injuries have been tied to the Karma battery, which is built by A123 Systems.

In March, a Karma battery failed during a test conducted by Consumer Reports magazine. Fisker recalled 239 Karma cars in December to fix a battery defect that raised the risk of a fire.

Robert Baker, the chief fire investigator for Fort Bend County, Texas, could not be reached. He told AutoWeek magazine that the Karma was in flames less than three minutes after the driver pulled into the garage.

The safety of electric car battery has been in the spotlight since last year when U.S. safety regulators opened an investigation into General Motors Co’s Chevrolet Volt after some battery packs caught fire during testing.

The National Highway Traffic Safety Administration closed the probe in January, saying that electric cars do not pose a greater risk of fire than gasoline-powered cars.

NHTSA is in contact with local authorities about the Karma fire, the agency said in a statement.

“I’ve worked homicide scenes with less secrecy,” Baker told AutoWeek. “There have to be about 15 engineers down here working on this one.”
