Battery (NiCad) Rejuvenator - Don't throw away those seemingly
un-chargeable, rechargeable batteries; they could very well be brought back to
life with the aid of this simple circuit ….(Tony van Roon's Tony van Roon) |
|
Battery Charger Takes on Two Roles - 01/01/98 EDN-Design Ideas: The NiCd and
NiMH battery charger in Figure 1 applies a battery fast-charge controller IC in
a way that not only provides peak-voltage fast-charge termination--as IC
was designed to do--but also precisely regulates charge current. The
design also features maximum-temperature backup shutdown. Efficiency exceeds 90%
at a VIN of 14V.....(design idea added 4/02) |
|
Battery Charger with LM317 - LM317 regulator is used to regulate the
voltage and current for this circuit. This battery charger should be used only
for Ni-Cad cells. Other type of batteries (li-ion, NiMh, Lead and Li-ion
polymer) needs special care so it cannot be used. …(electronic design added

Battery Chargers Indicates Rate of Charge - 05/25/95 EDN-Design Ideas: A
single LED indicates wher battery Chargers s delivering a trickle charge
or a fast charge, circuit designed to charge2-14 cells.....(design idea added

Car NiCd Charger - This circuit provides up to20-Volt output from a regular13.2V
automotive battery, to enable constant current charging of NiCd battery packs up to15
cells @1.2V (Tony van Roon's 18V total). (Tony van Roon's electronic design added

Charging NiMH Cells - The latest rechargeable cell on the market is Nickel Metal
Hydride (NiMH). It has a cell voltage of 1.2v (called "Terminal Voltage" as it is the
voltage across the terminals of the cell) and a capacity higher than previous types of
cells. It's a real advancement in technology....(electronic design added 08/08/08) |
|
Choosing & Using Nickel-Metal-Hydride (NiMH) Rechargeable Batteries - The number
of portable gadgets that we use has grown substantially in the last few decades. Many
of these, such as TV remote controls, some digital cameras, handheld GPS units, and
flashlights, are designed to operate on either disposable alkaline batteries or
rechargeable, and hence reusable, Nickel-Metal-Hydride (NiMH) batteries.….(circuit
added 03/09) |
|
Constant Current Battery Charger - A simple method of charging a battery from a
higher voltage battery is shown in the circuit below to the left. Only one resistor is
needed to set the desired charging current and is calculated by dividing the
difference in battery voltages by the charge current. So, for example if 4 high
capacity (4000 mA hour) ni-cads are to be charged at 300 mA from a 12 volt battery,
the resistor need,....(circuit added 7/02) |
