With the progress of the times, the development of the electrical industry has made unprecedented progress, and lithium batteries are the current reserve army of many electrical appliances. The lithium battery protection board is used as the core component of the lithium battery, and it has Effective protection, its protection has the main functions of preventing overcharge, overcurrent, overdischarge, short circuit, etc., which can protect the lithium battery, so the existence of the lithium battery protection board has become more and more thin. . Today, the Chinese Chuangfa will learn with everyone what should I do if the lithium battery protection board is not charged?

It’s actually very simple. First of all, we still need to use the switch of the multimeter to select the DC 20V gear, and then touch the positive electrode of the battery cell or the protection board with the red test pen. If the multimeter displays the output voltage, we will The analysis should be based on the following conditions: whether there is an output voltage and whether the cell voltage is normal. If the above voltage is not normal, we can basically judge that the protection IC or MOS tube has been damaged. At this time, it is enough to replace these two components.
