This handy circuit can be used to charge from one to 12 NiCd cells from a car battery. Up to six cells can be charged with switch S1 in the “normal” position. The LM317regulator operates as a simple ...

I designed a compact, standalone Li-ion battery charger that is simple to build, extremely affordable, and easy to integrate directly into projects.

First intelligent, OEM-integrated charging system engineered for commercial trailers maintains optimal battery capacity, reducing fleet downtime and maximizing battery lifespans.

Because stationary batteries and 48VDC power systems serve as lifelines for telecommunication networks, the reliability of these systems is of the utmost importance. Many system designers rely on ...

[Chris] was unhappy with the battery performance of his Rovio. It seems that he’s not alone, so he set out to reverse engineer the battery charging circuit to see if there was a fix. Boy is there, ...

Every EV user has wondered about this. There's no simple answer, but knowing the variables will help you better estimate the time it takes for an EV fill-up.
