  1. Self/team introductionDIY
enthusiasts, engaged in the small appliance industry2
  . Briefly introduce the projectTraditional
stove igniters are powered by dry batteries or power adapters. The disadvantage of dry batteries is that they pollute the environment and cannot be reused; the disadvantage of power adapters is that they require mains power support and cannot be used at all when the mains power is off.
[Please fill in during the competition phase↓]
  1. Describe the project detailsThe
purpose of this project is to solve the problem of being able to use lithium batteries to power the mains when the mains power is off, and to use the power adapter to power the mains when the mains power is on.
  2. Describe the challenges faced by the project and the problems solvedThe
challenges faced are overcharge, over-discharge, and over-current protection of lithium batteries and seamless switching between adapter power and lithium battery power.
* 3. Describe the key points involved in the hardware and software parts of the projectIn
the hardware part: DW03 is usually used to protect lithium batteries from overcharge, over-discharge, and over-current; TP4056A is used for charging management; dual PMOS tubes are used in reverse series to achieve power switching.
In the software part: For various protections of lithium batteries, hardware DW03 protection can be used, or software programs can be used for protection. Considering the volume, this system directly uses hardware components for protection, and does not involve software.

Self-introduction:
                Traditional stove igniters are powered by dry batteries or power adapters. The disadvantage of dry batteries is that they pollute the environment and the batteries cannot be reused; the disadvantage of power adapters is that they require AC power support and cannot be used at all when the AC power is off.
Project details:
                The purpose of this project is to solve the problem of being able to use lithium batteries for power supply when the AC power is off, and to use power adapters for power supply when the AC power is on.
Challenges faced and problems solved:
                The challenges faced are overcharge, over-discharge, over-current protection of lithium batteries and seamless switching between adapter power supply and lithium battery power supply.
In the hardware part: DW03 is usually used to protect lithium batteries from overcharge, over discharge and overcurrent; TP4056A is used for charging management; dual PMOS tubes are used in reverse series to achieve power switching. In the software part
: hardware DW03 protection can be used for various protections of lithium batteries, or software programs can be used for protection. Considering the size, this system directly uses hardware components for protection, and does not involve software.
