In 2022, Guangzhou Junpan Industrial Co., Ltd. was recognized as a "specialized, specialized and special new enterprise" and "innovative enterprise" by the Guangdong Provincial Government, which shows that Junpan Co., Ltd. has long been deeply engaged in the field of battery charging, focusing on the charging mechanism of different power batteries, energy storage batteries and starting batteries under various physical models, forming a new industry-leading charging theory on the basis of mechanism research, and perfectly realizing the numerical control safe fast charging of lead-acid batteries, lithium batteries and other new batteries through digital control and artificial intelligence means, and the end If you want to be safe, you have to charge slowly", "If you want to charge quickly, you must take risks".

As a specialized and special new enterprise, Junpan shares comply; "Specialization, refinement, specialization and novelty", in order to adhere to the four modernizations, Junpan Co., Ltd. never catches up with the trend to imitate similar products, always adheres to original research and development, decades of hard work, so that Junpan "no one has me, people have me excellent, different, leading the trend" corporate culture is well known in the industry.

1. Over the years, through the study of the current-forming reaction of lead-acid batteries, the process of reducing the plates from PbS04 to Pb02 and Pb during the charging process of lead-acid batteries, the transfer process of HS04 and HS04 concentration of electrolyte from H20, and the different steps of the charge migration process can lead to the disadvantages of slow charging, easy gas evolution, easy filling drumming, filling and short life of lead-acid batteries. Creatively proposed: the use of frequency conversion square wave intermittent charging technology, so that the three movements are synchronized in stages, to achieve 0.5C safe fast charging of lead-acid batteries, life extension of 25~30%, output increase of 15~20%, truly achieve lead-acid batteries beyond lithium batteries, the technology has passed the national appraisal, is the world's leading technology, and obtained invention patents. 2. With the rapid rise of power lithium battery and new energy industry, put into lithium battery charging theory and technology research, based on the lithium battery charging, the positive electrode material is oxidized, the negative electrode material is reduced, lithium ions are de-intercalated from the positive plate and transferred and embedded in the negative electrode, on the basis of Mass's law, the MAAS curve is discretely fitted, and through a large number of experimental data, as a constraint boundary, a Maas fitting charging curve with dynamic relative charging voltage (Vt/CV) as the independent variable is formed. Based on this curve, the charging current is dynamically adjusted, so that the positive electrode in the lithium battery charging process is de-intercalated, and the ion migration and negative electrode are coordinated, so that the charging amount is always equal to or slightly less than the battery power receiving capacity, truly realize the safe and fast charging of lithium batteries, and eliminate the malignant safety accidents caused by charging, this technology has passed the national appraisal and obtained the invention patent. 3. The amorphous iron-based magnetic material is used in the charger technology to realize the low-frequency and small volume of the high-power charger, and the replacement of MOS with IGBT greatly improves the efficiency and reliability of the charger, and ensures excellent transient response characteristics accordingly. 4. Obtained a large number of invention and utility model patents in power electronics (switching power chargers, etc.), and formed a complete technical route and product system of chargers. (25 series, 88 models, 680 specifications 100W~100KW charger) 5. It is recommended to overcome the shortcomings of slow charging, less cycle and small output of lead-acid batteries by promoting lead-acid battery frequency conversion square wave charging technology, and carry forward the advantages of rich raw materials, low cost and extremely high safety of lead-acid batteries, so that lead-acid batteries continue to play a role in many fields. a. Lead-acid batteries continue to be used on equipment with weighing requirements such as electric forklifts. b. Promote the use of lead-acid batteries in places of unlimited size such as energy storage. c. In areas with high safety requirements, lead-acid batteries such as electric vehicles, mopeds and other batteries that need to be charged at home should continue to use lead-acid batteries, (after all, lithium battery charging accidents are more "not allowed to go upstairs into the house") 6. It is recommended to strictly standardize lithium battery chargers, prohibit simple chargers that do not have dynamic adjustment of charging current and full of shutdown functions for lithium batteries, lithium batteries strictly prohibit blind fast charging, and promote Maas fitting charging technology for DC fast charging piles such as new energy vehicles. It is clearly stipulated that the charging rate corresponds to the upper limit of the charging voltage of lithium batteries to avoid safety accidents and ensure the safety of people's lives and property.
