Description
technical field [0001] The invention relates to a low-frequency soft pulse charging circuit, and at the same time, the invention also discloses a low-frequency soft pulse charging method. Background technique [0002] In the entire existing charging technology field, there are generally two charging technologies: [0003] One is the constant direct current charging technology, and the other is the high-frequency rectangular wave pulse charging technology. These two technologies have corresponding disadvantages. The former charges the battery, and the ions have no diffusion time, which makes the ion concentration around the inner plate of the battery very high. , so that the electrochemical reaction is getting slower and slower, and crystals will appear, making the battery easy to polarize, and the battery life is getting shorter and shorter; the latter has a high frequency and a small pulse gap, and the result is equivalent to its average DC current.
