Why do we remain optimistic attitude after electric scooter’s explosion event?(part 2)

From a commercial point of view
1. The importance of product quality
Blindly seeking shipping, not pay attention to quality, multiple bombings shocked the world, the Chinese manufacturer onto the cusp, almost ruined this product. Foreign government’s attitude, Amazon’s measures for the industry, people on an important lesson. So that more people realize the importance of quality standards important. For this reason, many people pay the full tuition, the future will be more cautious, more standardized everything.
Koowheel Hoverboard only use the original Samsung batteries, “Xinaoma/Hanghong motors( famous brand with best quality )”, ” Taotao Intelligent Technology ” mainboard , ABS plastic case with UV certification, Charger with UL certification., and we have a 20-30 degree climbing test, and we have the unique testing machines in Shenzhen to test the balance, the speed, the maximum load data for each scooter.
Their electric scooter support UN 38.3 (battery) and UL 60950-1/BS (charger), all of our raw materials comply with national safety production standards.

2. The importance of product profitability
Impulse sales price war, only to ultra high failure rate, completely unable to afford overseas sale, many people throw good money after bad. Vicious competition counterparts, eventually destroy themselves, cool guests. No profit companies do not last long, there is no profit product is bullying. Eventually there will be more companies realize the importance of profits, more to think about how to sell their products at high prices.
3. The importance of intellectual property
This balance board incident everyone the biggest headache is the patent issue, so that almost all enterprises in a very passive state. Many people complain that frenzied patent holders blindly, not knowing fundamental reason is that their own weak awareness of intellectual property.
It is worth about science. Before a lot of people do not know the brand of the important, but do not know the importance of intellectual property patents. Patents, not only is the intangible assets, it is the competitive tools. More importantly, it can also create profits for the company. In other countries, the annual income for the enterprise patent is an important part of corporate profits. For more information, please visit http://www.koowheel.com

Why do we remain optimistic attitude after electric scooter’s explosion event?(part 1)


Amazon event in December, a great shock throughout the shilly car industry, so that the industry reshuffle ahead of the start. At this point, some people choose to wait and see, someone hesitated and want to quit, some people think this is a big opportunity for the next year ,it was also worried about the survival of the industry. . .
In my opinion, balance scooter not only will not die out but will have greater development for the next year.
From a technical field analysis
First, motorized scooter although there have been more than 10 years, including the current shilly car but several techniques used are very new, brushless motors, single sine wave control system, balance algorithms. The technology also uses the drones and robots products. The future of these technologies will be applied to more products and in the field, and will continue to innovate.
Analysis from industries
In my opinion, electric scooter just one of a product among balance. Electric hoverboard involved in several different areas in the future will be as big:
1. The means of transport
Shortage of resources, environmental pollution, this series of urban congestion in front of us, a new means of transport energy is undoubtedly the next few years the trend and the trend. The balance car gradually be the short travel by more people , small-scale means of transport. For everyone concerned about the balance car right of way and safety issues will, over time, to expand the market, the government’s attention gradually been resolved, any new product will not be smooth sailing process popularity.
2. Recreation
Millet released KOOWHEEL balancing scooter, positioning it as a toy, shilly car from abroad consumer use, most of the bias entertainment purposes, which shows that the product use can be diversified. In the future there will be more balanced vehicle technology-related toys appear.
3. Robot
Some brands is defined the balance car as robot, into the concept of things to make it more intelligent, and can be applied to family, medical, military, and other fields wrecker. Various balancing scooter will appear everywhere.

The different between import battery and domestic battery

Recently, due to a series of fire accident which caused by self balancing scooter, it seems that Amazon has begun to take actions: The company not only requires manufacturers to provide safety certificate, but remove some products off the shelf.
Battery explosion to Electric scooter, it depends on battery recipe which determines the safety of battery . Compare domestic battery to import battery , import batteries,  in the instant of the explosion, the temperature rises less than a thousand degrees while domestic battery rises to thousands of  in the unit time, the difference is significant. please notice the following photo about The difference between import battery( Samsung battery cells) and normal battery.

Battery explosion of Self Balancing Scooter

Battery explosion of Self Balancing Scooter, a battery itself recipe, formula determines the safety of battery materials. In contrast domestic battery and battery imports, imports of batteries, instantly in the explosion, the temperature is only less than a thousand degrees, and can rise to thousands of domestic battery in the unit time, the difference is significant.

Another argument is the rigor, imported batteries standard is bound to 5C 5C even better, we certainly have to 3C domestic standard to verify. For self balancing electric scooter this large currents required battery, if the rate is insufficient, under conditions that will produce high current severe heat, if the heat rises too quickly, while PACK internal process did not do, cause a short circuit between the batteries, that there will be problems.
So many customers ask battery must ask is not 5C, is not enough to 5C? This is indeed very critical
Then there is a possibility that most people will ignore the problem, and that is consistency. Multi-cell multi-string and consistency requirements are very strict, what is consistent, that is simply require that 20 batteries (Series 2 and 10) together with the charge and discharge together. If consistency is not good, it must be high voltage sinking batteries easy touch overcharge protection
It is generally easier to have an accident while charging. Charge Where an accident? I think that is the consistency.

Simply make a graph, the situation on the left is OK, and the right is dangerous, if you do the battery factory PACK more responsible, he may have a protective plate to conduct the inspection, relatively speaking, by the issue of consistency broke out on a bit better. Because our cells are 10 strings, single highest voltage batteries is 4.2V, 10 string is 42V, and if there is an imbalance in the battery charging time, a high one low, low if 3V, that high would charge to 5.4V, and we think is not the case. But if it happens to do PACK irresponsible manufacturers, protect the plate is not tested, and is responsible for pipe 5.4V batteries Fengyun protection has failed, it became inevitable that the explosion.
So, no matter you or your friends would like to buy electric scooter, must be consider the safety factor, it is suggested that choose high reputation’s self balance scooter supplier. It is said that Most of consumer would choose “Koowheel” , which is the biggest supplier of best quality and output in Shenzhen,China. Koowheel choose the best quality Samsung batteries also the raw materials  comply with national safety production standards.
