On the afternoon of June 9, Wang Wei, Deputy Director of the Investment Promotion Bureau of Northern Shenyang New Zone in Shenyang City, and Wang Mingwei, Assistant Director of the Investment Promotion Bureau of Northern Shenyang New Zone in Shenyang City, visited our company. The leadership team of Liaoning Goodao Technology Co., Ltd. and Xiao Bixiang, chairman of Xiamen Goodao Technology Group Co., Ltd., accompanied the visit. They got warm reception from Wei Yanping, chairman of Better Technology Group Limited. Both of them made deep communications.

The electric vehicle battery stayed idle at home for a month,Why only half of power is left?Is it your own misuse? Or is there something wrong with the quality of the battery itself?

in order to further enrich the leisure sports life of employees, enhance their awareness of physical exercise, promote the spiritual civilization of the company and the construction of corporate culture, "Exercise in summer burns my calories" sports meeting in Better Technology Group Limited was successfully held in Weifeng Sports basketball training camp.

How to use and maintain the battery of electric vehicle has always been a topic of concern. "Do I need to charge the battery I just bought?" "How to maintain?" "Do batteries need to be charged after being placed for a long time?", this article will share you some common problems of electric vehicle battery maintenance, hope it can help you after reading.

On May 25th, in order to promote the company's learning community to be implemented faster and better, Better held a learning community kick-off meeting with the theme of "Sharpen yourself and create the future", and it was also a new employee welcome meeting which aims to guide the company's employees to actively participate in Learning Community activities, learn and practice, improve themselves, and promote new employees to integrate into the company's development atmosphere quickly,enhance communication between new and old employees.

The failure of lead acid batteries is the result of many factors, which is determined by the internal factors of the plate, such as the composition of active substances. Crystal form, porosity, plate size, grid material and structure also depend on a series of external factors, such as discharge current density, electrolyte concentration and temperature, discharge depth, maintenance status and storage time. Here are the main external factors.

At this FENIBAT-2022 exhibition in Brazil, BETTER showed the company's independent research and development of the lead-acid battery equipment production line, energy storage lithium battery, patent certificate, etc. which attracted many visitors to stop for consultation.

the phenomenon that the active material on the battery plates are gradually turned into lead sulfate with coarse and hard crystals full of plate surface due to deep discharge (too much) or long-term insufficient charge, which will block the plates micropore and hinder the electrolyte penetration and conduction current, thus the battery charging and discharging performance is extremely deteriorated, and the actual capacity is seriously insufficient; and it could not be reduced to lead dioxide and spongy lead by conventional charging methods.

Lead acid battery is mainly composed of positive/negative plate group, separator, battery container, electrolyte, battery cover, etc. The electrode is mainly made of lead and lead oxide, and the electrolyte is sulfuric acid solution.

Do you know how to group the batteries? Do you know how to calculate the driving mileage of electric vehicles batteries? Do you know how to add repair fluid to the battery? If you don't know, you must read this article.

However, the above phenomenon is not common, and most chargers will not or do not often have similar problems. This kind of charger is not only rare, but also a relatively old one that has been used for many years. The correct way to use the charger is that at the later stage of charging, although most of it has been charged, a small amount of sulfurized substances on the plate are not completely reduced.

If battery overheating is caused by excessive discharge current, there may be the following reasons:
