Description

technical field [0001] The invention belongs to the field of electronic technology, and in particular relates to a lithium battery rapid charging and discharging device and method. Background technique [0002] With the development of today's electronic technology, digital products such as MP3, MP4, mobile phones, and handheld computers are updated at an extremely fast speed and emerge in endlessly. The continuous enrichment of the functions of various electronic products and the continuous increase of the screen make the power consumption doubled, but the power of the battery cannot be doubled, which leads to the shortening of the use time of the mobile phone, which brings the work and life to the user. inconvenience and hassle. In response to such a situation, a power bank specially used to charge mobile phones and other electronic products came into being. [0003] Existing charging treasures all use batteries to store energy, and in order to limit the heat generated by...
