Lithium batteries have, practically solitary-handedly, ushered in the period of the electric automobile, as properly as battery power storage of grid power and a good deal of other technological improvements not probable with older battery chemistries. There’s just just one significant downside: these lithium cells can be very finicky. If you are incorporating 1 to your very own task you are going to have to be incredibly thorough to take care of them specifically how they are intended to be dealt with using a thing like this boilerplate battery protection circuit designed by [DIY GUY Chris].
The circuit is based all around the TP4056 integrated circuit, which handles the charging of a one lithium cell — in this design working with supplied electrical power from a USB port. The circuit is able to charge a cell primarily based on the cell’s present cost point out, temperature, and a model of the mobile. It is also paired with a DW01A chip which protects the mobile from many undesirable conditions these kinds of as in excess of-present-day, overcharge, and about-voltage.
The best point about this style and design isn’t the design and style alone, but that [DIY GUY Chris] developed the circuit schematic particularly to be very easily copied into PCB layouts for other jobs, which indicates that lithium batteries can additional easily be built-in immediately into his other builds. Be guaranteed to check out out our primer on how to deal with lithium batteries before trying one of your personal types, though.
