Every time you install electric bicycle batteries, have you ever wondered about the development history of batteries and why most of them are now using lithium batteries?This post will solve your doubts, let you understand the birth of the first electric bicycle battery to the development of today's lithium battery.

 

 

 

 

Knowing the battery history may help you make a better battery choice.Let's have a look together!

 

Alessandro Volda:The birth of volt batteries

 

When it comes to batteries you have to mention a character, the Italian physicist Alessandro Volda, he invented the Volt battery in 1799 known as the stack.It was the prototype of the first battery in human history and laid the foundation for later battery development.

 

The first battery for use in vehicles

 

In 1834 Americanin Thomas Davenport used dry batteries to make the first DC motor driven electric vehicle.But this dry battery cannot be charged and after use, it needs to be replaced with a new battery, which is not an ideal choice in terms of convenience and cost, therefore dry batteries that are easy to cause pollution and cannot store electricity are soon eliminated.

 

 

 

Breakthrough in lead-acid batteries, development of electric vehicles

 

Since 1859 French physicist and inventor Gasten Pollent invented the rechargeable lead acid battery.Since then lead acid batteries with low cost high cost performance and high safety have quickly eliminated dry batteries.

Time to 1881 years Ghostov Truff of France successfully transformed an electric tricycle and exhibited in Paris and the first tricycle using lead acid batteries as energy storage was born it weighs 160 kg and the speed is only 12 km/h Gustav Truff is recognized as the inventor of the first electric car with the use of lead acid batteries and the improvement of battery performance the advantages of electric vehicles are beginning to highlight coupled with low battery prices making electric vehicles gradually become the first choice of celebrities.

 

 

 

The drawbacks of lead-acid batteries are becoming increasingly apparent

 

However the energy density of lead acid batteries is very low the battery pack is large but the capacity is very small cannot meet the control of its own weight and the consumption of driving force of a car and the service life of only 10000km per year it is difficult to use on a large scale in mass production cars especially with the gradual expansion and improvement of roads there is also a demand for long distance travel.At this time the drawbacks of the short driving range provided by the lit acid battery began to appear. At that time the driving range provided by the battery was generally 40 to 65km and the top speed was about 30km per hour which could not meet the needs of the market.

 

Even in 1899, nickel cadmium and nickel iron batteries were invented although compared with lead acid batteries their energy density and charge and discharge times have been greatly improved and the electrolyte is non-combustible safety is guaranteed and the manufacturing process is mature.However the nickel metal hydride battery charging efficiency is general the working voltage is low can not use high voltage fast charge and the cost is relatively high not suitable for use as a power supply.

 

 

Batteries are facing challenges, development is stagnant

 

With the development of Texas oil and the improvement of internal combustion engine technology the market has gradually been replaced by internal combustion engine driven vehicles and electric vehicles have slowly come out of people's vision this batch of lead acid batteries began to gradually lose their advantages after 1920 and their development completely stalled.

 

 

The emergence of the oil crisis has once again turned people's attention to batteries

 

In the second half of the 20th century there were three successive oil shocks which also awakened developed countries such as the United States Britain and Japan to the dangers of seeding energy to other countries and the need to wing themselves off their heavy dependence on oil. Since then,many countries and car companies have once again turned their attention to batteries and began to invest a lot of resources in battery technology research.However,the breakthrough of battery technology is not a matter of overnight overnight and many car batteries are still dominated by LEED acid batteries.

 

The use of lithium batteries has laid the foundation for electric bicycle lithium battery packs

 

As early as 1976 British scientist and British scientist M.Stanley Whittingham proposed the concept of lithium batteries and created a lithium battery that can charge and discharge the voltage is more than 2V although there are many problems in safety have not been solved,but he can still be called the founder of lithium batteries.

 

Four years later John B.Goodenough of the United States developed the lithium cobaltate battery the voltage of this battery is double that of Stanley's lithium battery reaching 4V.

 

In 1985,lithium batteries experienced an important breakthrough Japanese scientist Akira Yoshino. Akira Yoshino in the study of lithium-ion battery anode materials proposed the use of graphite material carbon anode replacing the original metal lithium anode this technology is called lithium ion battery revolutionary breakthrough.

 

The rapid development of lithium batteries has brought great convenience to our ride and life

 

The use of carbon negative electrode can reduce the weight and cost of the battery while improving the safety and cycle life of the battery.Since then,the application range of lithium batteries has further expanded including electric vehicles energy storage systems aerospace and other fields.

 

 

 

In 1997, John B. Goodenough developed the low-cost lithium iron phosphate LiXFePO4 cathode material, which accelerated the commercialization of lithium-ion batteries. The advantages of lithium iron phosphate batteries are safety, good charge and discharge performance, lower cost, and no pollution to the environment, with excellent battery cycle life, low self-discharge (inventory storage life is very long), which makes traditional lead-acid batteries, nickel-metal hydride, nickel-cadmium batteries are eclipsed.

 

The advantages of lithium-ion batteries are very obvious high working voltage small size light weight high energy no memory effect no pollution small self discharge long cycle life and become one of the most suitable batteries for electric bicycles.

 

ChamRider batteries continue the advantages of lithium batteries to provide more powerful batteries for electric bicycles

 

After a series of introductions, whether to let you have a new understanding of electric bicycle batteries?

 

In fact, since ancient times, people have been pursuing not only small size, light weight, but also to provide large-capacity E-bike batteries.At present, the lithium battery pack can just solve this demand for everyone, not only its high energy density, but also the use of environmentally friendly materials, so more and more electric bicycles, electrical appliances and so on are using it.

 

Our ChamRider battery continues the good advantages of lithium batteries. In the cell, we choose high energy density cell, to provide customers with Samsung, LG, MoLicel, Panasonic and China famous cell brand such as DMEGC, EVE and so on. While ensuring the quality of the cell, it has ultra-high cost performance.

 

 

In terms of capacity, this is a big advantage of our ChamRder, we can achieve larger capacity in the same product, such as our HailongMAX battery, with 48V25AH super capacity, is a breakthrough in the battery industry, uilt-in Samsung battery cells ensure more than 1000 lifecycles,Up to 100km per charge.

 

 

In addition, the BMS in the battery is also important. ChamRider batteries adhere to the use of self-developed BMS protection batteries, so that customers can rest assured. Our BMS maintain 1.5-2 times the amplification current, ensuring a longer service life. BMS built-in Bluetooth, check the battery condition at any time is also a major feature of our battery.

 

 

 

Now, do you know why lithium batteries are chosen by more people as batteries for electric bicycles? The quality of the battery directly affects the use effect and feeling of the electric bicycle. A good battery pack can help you move freely on the road and enjoy more riding fun. The ChamRider battery will be your best companion on the road.
