... trickle charge a capacitor. when capacitor has reached a good charge, it would connect and begin to charge a battery. when the battery reaches a specific charge, it would turn on the computer. ..... trickle charging is performed in a (...)
you shoudl use a current regulated smps...then change to voltage regulated control when the voltage gets to about 13.8v. ..but actually its a four stage process. 1....trickle it up 2....big current in 3....Maintain at voltage 13.8V till current dies down to v small 4...maintain at the flow voltage
I'm not sure if you are saying the motor is a motor or it's a generator. I suspect you are using it as a generator. As you are not using any excess power it might generate, just regulate it's output to keep the voltage at trickle charge level for the battery and a split off it to a regulator for the phone/Pi. If the motor produces more (...)
Go to or Energizer Technical Info to learn about the details of charging Ni-MH battery cells. They must not be trickle-charged and the charger IC must detect that they are fully charged then shut off. I think the fast charger IC you posted will quickly destroy a Ni-MH (...)
I am working on a project that requires 12VDC and at least 20 Amps - for maybe 20 seconds, three times a day. The idea of using a used car battery occurred to me. If I look to buy a used one, how should I test it ? If I go this route, would it be fine to trickle charge it continuously - maybe connecting a power supply set to about (...)
It sounds as though you have a 12V power supply. It provides power continually to some device. Is this correct? So suppose you were to hook up to the battery in the middle. You regulate the power supply to 13.8 V (a normal constant condition for a 12V battery). Perhaps as low as 12.8 V. The battery would trickle (...)
1. It allows a trickle charge current through to the battery even when the regulator has shut down. It also makes it think the battery is fully charged if it is disconnected so the regulator automatically shuts off when no battery is present. 2. It allows the IC to 'sink' but not 'source', (...)
It sounds as though you want to construct a project which consists of three functions: 1) Convert mains AC to 5 VDC. 2) Step 5V up to approximately 15 V, to charge a 12V battery. 3) Stop charging the battery when it is full. Resume charging when its voltage drops. (Charging may be a trickle rate.) Is this correct?
In it's simplest form, if the trickle charger is set to produce 2A, any diodes rated at more than 2A will work. I doubt the ~0.7V drop per diode will cause any problems. I would have concerns about the charge being shared equally between batteries though. It is true that if each battery is identical, and reaches full (...)
battery charging current is 6A. Circuit draws 3A. charger has to supply both loads. charger should be able to supply 9A at 14.5V continuiosly. When battery is charged,it goes into trickle charge stage (by loweing its voltage to 13.6V and voltage stay there). The cut-off (...)
Not so sure of these Nicd batteries.. but terminology may mean the same for all batteries... In Li-ion, when battery charges to maximum capacity and if still the charger is connected.. trickle charging takes place.. To say more accurately, If max. voltage is V, and voltage drops by some mV, trickle charging (...)
Can Lead acid batteries be slow charged at C/10? Then when fully charged, can they be trickle charged at C/20 or therabouts?.....and how do you know when the lead acid battery is fully charged so that you can transfer to trickle charge? We wish to look (...)
Dear abdulwahababid, First, you'd better get to know the process of charging: trickle charge, CC and CV. Consider it in this way: If CC(constant current) stage needs 1A charging, and the resistance between the source and the battery is 1 Ohm, Also if the battery will be charged to 10V (CC stage (...)
Lot of charging methods available...constant voltage charging, constant current charging, pulse charging, trickle charging, burst charging, etc... most of them prefer constant current charging... We can sense the charge level of a battery by measuring the current flow... If the battery is empty the battery (...)
If your charge manager looks after preconditioning at lower current and post trickle charge and low current, and charges for 1C, it seems ok. MCP73871 is Microchip's solution.
If you trickle charge the battery at 13.8 vols you can leave the charger on forever. As you can't use home electricity then the next best bet would be an array of solar cells. Frank
If you want to charge batteries whilst drawing a load current you must ensure that the total input current is at least equal to the load current + the trickle charge current
It's really neither. The charging current is about 1A which is too high to be either a trickle or a float charger unless the battery is a huge one of >>100 Ah capacity.
To fully charge a 12 V lead acid battery, you'll need about 13.8 to 14.4V constant voltage (different for trickle charge or intervall charge). Also the DC adaptor needs current limiting according to the rated charge current of the battery. Most sealed lead acid batteries (...)
does this mean that a minimum of 18.7V (Which obviously wont be the output of 12V reg) is required at the input of LM317 to work? Yes. There is another , fundamental, shortcoming of the circuit, which I failed to mention. The 12V switchmode p.s.u. needs an input voltage above 12 - which can't, of course, be
