After using an electric car for a year, you will find that the battery costs the most. A set of lead-acid batteries costs 300 to 400 yuan, and will be scrapped in more than a year at most, which is really heartbreaking. Can the battery run for a few more years? Of course! This is a good thing that benefits the country and the people and protects the environment. Many people have studied it ten years ago.
Electric vehicle batteries are traction batteries. They are different from other batteries. When riding electric vehicles, we all hope to ride faster and farther. It is inconvenient to charge as we go, and we hope the charging time will be shorter. Therefore, electric vehicle batteries have larger discharge current, deeper discharge depth, larger charging current, and longer charging interval. This quickly damages the battery performance and seriously affects the battery life.
How to extend the service life of the battery?
First, the car must be light and perform well. The battery life of the simple model is relatively long because the wheel diameter is large, the vehicle is light, and the battery burden is light. Some cars use brushless motors or high-speed motors, and the discharge current is smaller. The current of such a car when cruising at a speed of 20 kilometers per hour is about 4a, and the life of this kind of car is relatively long.
Second, choose a good quality brand for the battery.
Third, choose a good charger. A widely circulated saying in the industry is: Batteries are not worn out, they are charged. So use a good charger.
Fourth, if the car is not using the battery for a long time, it needs to be charged once a week. (If the battery is not charged for two to three consecutive months, the battery will become useless.)
Fifth, pay attention when riding a bicycle. Generally, use human assistance when starting and climbing, and do not overload or drive fast. Recharge frequently.
Sixth, battery vulcanization is the number one killer causing battery short life.
Sulfation is the production of lead sulfate particles during the charging and discharging process of the battery, especially when discharging with high current. For example, if a 10ah battery is discharged with a current exceeding 10a, more lead sulfate particles will be produced on the plate material. This reaction is irreversible under the current usage conditions and charging methods of electric vehicles. As time goes by, Such particles will accumulate on the plate material. Since these particles are non-conductive, the external characteristics of the battery are increased internal resistance and reduced capacity, causing a decrease in the capacity of the entire battery pack and a loss of high-current discharge capability (actual performance: gradeability) is further reduced. This phenomenon is called battery vulcanization. Once the battery is sulfated, it will not only reduce the capacity of the negative plate of the battery, but also increase water loss and softening of the positive plate, affecting the life of the entire battery.
Casio introduced technology from the United States and has successfully developed a battery regenerator and obtained a national patent (patent number). It has completely solved this problem and can extend the life of new batteries by 2 to 3 times. , it can also repair old batteries to restore the mileage to about 80% of the previous value, and extend the life of old batteries (six models of electric vehicles and automobiles)
The following is an introduction to batteries. The working principle of the regenerator.
The household battery regenerator uses pulse electric waveform to repair and maintain the battery. The working principle is different from the repair instrument in the battery repair shop, and it needs to be used for a long time ( About 2 weeks). It can effectively remove sulfuric acid crystals. Its basic working principle is:
1. Continuously charge and discharge special pulse current (similar to corona discharge) to remove the lead sulfate covered on the electrode plate. The precipitate is gradually catalytically decomposed without damaging the electrode plate.
2. Lead sulfate can be 100% decomposed into fine particles: lead sulfate is decomposed into lead, lead dioxide, and water and reduced in the electrolytic solution to restore battery capacity. , to extend the service life (the stripped lead sulfate is restored in the electrolyte).
The removal of sulfuric acid crystals by pulse waves has long been recognized by many experts and scholars at home and abroad. However, there are tens of millions of pulse waveforms. Not all pulse waves can effectively remove sulfuric acid crystals. Although most medium and low frequency (20hz~20khz) sharp pulses with a certain amplitude can also have some effect on eliminating battery vulcanization, only a few waveforms can. The actual repair effect depends on the release time of the pulse wave, the pulse amplitude (depth and width), and the size of the pulse current. The technology is endless, and finding a good pulse waveform requires long-term and continuous exploration. and test. When eliminating vulcanization, a low-frequency peak wave with a certain amplitude and width acts on the discharge and rest processes; a medium-frequency pulse acts on the charging process.
Appropriate mid- to low-frequency composite waveforms are often more effective than a single waveform.
This product has been on trial sale in China for two years. Judging from various data feedback, the response has been very good, ranging from the purchase by a single person in the Xidan Civil Aviation Building to the group purchase by many people in the unit. He said: I used to be able to ride home after one charge, but now I can ride twice on one charge. I was going to replace the battery, but when I saw this product in the newspaper, I bought it and tried it. It only cost 78 yuan. , it’s better than replacing a set of batteries for over 300. I didn't expect such a gadget to actually work.
