Fast Charge Circuits for NiCad Batteries - AN37 Linear Technology
Safe, fast charging of NiCad batteries is attractive in many
applications. This note details simple, thermally-based fast charge
circuitry for NiCads....[Application Note]
Fast PIC NiMH/ NiCd Battery Charger - This battery charger
charges a NIMH 5-pack battery used in the BiPed robot in less than 1
hour, and charges the 10-pack NiCd used in the Snuf robot in about 30
minutes. To prevent overheating of the battery, the charging current
is turned off….(design added 11/08)
High Speed NiCd Charger for Electric R/C - A few years back, I published a
design for a Low Cost Thermal Peak Detection Charger. Since then, I've designed
several other chargers, in my ongoing quest to avoid having to spend money. Of
course, in building all these designs, I've probably spent more than a really good
commercial charger would have cost me. But designing and building is half the
fun... [Stefan Vorketter]
Intelligent NiCd/NiMH Battery Charger - This cheap and easy to build NiCd/NiMH
Battery Charger is suitable for automatically charging a wide range of batteries
for many applications. Proper chargers are usually expensive and cheap chargers
supplied with the original equipment often incorrectly charge the cells and
dramatically shorten their life. ….(electronic schematic added 11/08)
Low Cost Thermal Peak Detection NiCd Charger - The electric model aircraft
and car industries have produced a bewildering array of field chargers for NiCd
motor battery packs. These range from simple 6 or 7 cell chargers consisting of a
resistor and mechanical timer, to more complex chargers with peak detection,
cycling, and the ability to handle 36 cell packs.... [Designed by Stefan
