The leap forward of these batteries for electric bicycles will be brutal. We can remember for those who are not aware of today in the sector, than normal today are electric bikes battery capacity between 8 and 15 ampere hours. In the case of the battery of graphene will be passed to a capacity of no less than 55 ampere hours working with 36 volts. These are 1,995 Watt hours. Nearly 2 kWh. In a very compact package it multiplied almost fourfold the capacity of current batteries, increasing the range to 250 kilometers per charge. It will be possible to launch smaller packs of batteries, occupying a fraction and at lower cost. And speaking of weight. If a media pack of normal electric bikes is around 2.6 kilos, batteries weigh 55 Amperes graphene only 1.9 kilos. One thing very important on a bicycle. To all this we must add him to podriar load in 5 minutes and have no memory effect, lasting almost 3 times more life use and do not explode. We need to consider these data that I describe below and compare them. For agamos not a true idea of ​​what the graphene batteries used in electric bikes compared with the current. The battery is the main component of the technology of electric bikes also calls. pedelec. or. e-bike. formerly they were usually of ácidoplomo. from. Nickel-cadmium. or. Nickel Metal Hydride, but today are lithium ion. The battery had a capacity of up to 24 Amperes hour and with voltages of 12, 24 or 36, and 15 ampere hours, for 48 volts. The oldest NiCad batteries put up with ideally, a thousand loads, as had 85% of its original capacity with that number of refills, therefore considered them worn. With nickel metal hydride batteries with 400 to 800 cycles, and they are considered worn. The normal charging time depending on the type of battery is about 2 to 9 hours. The considered more expensive and very light, are the lithium ions, they are now used by most manufacturers and have a range of up to 100 kilometers of moderate pedaling with a battery capacity of 15 Amperes half hour. Lithium batteries can not tolerate frost and should not be charged to freezing temperatures. For safety, the chemical composition and quality of the electronics are crucial. Especially with short circuit and over voltage, the lithium ions react very strongly. It is useful to consider not only the ability but also criteria such as duration, memory effect, charging time, weight, safety and environmental protection. Manufacturers outfitting their electric bikes with NiCad batteries, usually delivered AC adapter Discharging the battery completely before charging, in order to reduce the memory effect. The Nickel Metal Hydride batteries have a much smaller effect of memory. With lithium-ion batteries no memory effect. A battery lithium iron phosphate is much more long-lived than a lithium-ion battery. Its use significantly reduces operating costs resulting from wear of the battery. Which they are the S-Pedelecs? The S-Pedelecs are bicycles calls without limits retricciones the listed electric bikes instead classified as mopeds. The use of S-Pedelecs involves additional risk. Not only they reach a higher average speed beyond 45 km / hour. They may also have greater autonomy. Electric bikes are perfect for all those who believe that another way is possible to move transport. clean vehicles, environmentally friendly. They help to make our cities and towns more pleasant. Electric bikes allow us to travel long distances without major efforts. We can go to work, enjoying every assisted pedaling. Up to the mountains for the weekend and travel along the roads and paths that are not within our reach with a conventional bike. It is increasingly common crossing with them. More and more ways to enjoy the electric bikes there. new measures to promote its implementation in cities are incorporated. a vehicle without complications, without a license, insurance or taxes. This is an alternative means of transport. Egon Gelhard of Zülpich, laid the foundation of principle for bicilec in 1982 by a study, “E-bike-Gelhard”. Tienian pedals turn, depended traction motor pedaling efficiency. This idea was implemented for the first time in a bicilec, with which he participated in the Tour de Sol. In 1990, and won in the category. Michael came from Kutter, which he founded in 1989. “Schweizer Unternehmen Velocity”. (Now Dolphin E-Bikes). From 1992 he launched prototypes to the market and in 1995 became production. Kutter. It is the inventor of the control by EOV. (EOV. Is an acronym for Electronic varable Overdrive). From 1993 the Japanese company Yamaha. it provided the bicilec more widely in Japan under the name “Power Assist”. Yamaha introduced control by PAS (PAS is an acronym for Power Assist .
