There are many companies making batteries for the Galaxy S5 smartphone. None of them say its maximum allowed output current. It is Lithium and it is not protected so its maximum allowed continuous output might be 20A or more. I think your battery will be fine delivering only 1.5A. I use 325mAh Lithium-Polymer model airplane batteries. Its maximum
IMHO "I want to" translates as "I should study literature". There are models for different aspects of battery behavior, e.g. frequency dependent impedance 129916 Also models of the nonlinear charge/discharge characterictic.
My radio controlled model airplanes helicopters and drones are powered with Lithium-Polymer batteries. They are small, lightweight and very powerful. I have a tablet but I do not know if its Lithium battery is the Polymer type.
Dear Members For the past year or so we have been working on an exciting new battery technology, and we need your help to evaluate the business and pricing model. The short survey below has only seven questions and will take less than a minute to complete. Your feedback will help us make important decisions regarding the direction and viability
I can't imagine that a tiny 100 nF capacitor has noticeable effect when parallel connected to a 1.5 Ah battery. But you can refer to the battery model parameters and calculate impedances exactly.
hi, i wish concuved a model of battery with simulink /matlab2009, i cherched a help in someones please. thank's. Cordially. said76.
Consider a battery & capacitor in series... while it's not an optimum solution, it should yield a more realistic charge/discharge curve, compared to a capacitor alone. Place a resistor across the capacitor, to simulate self-discharge. Also put a resistor in series, to simulate some amount of internal resistance. To simulate capacity of a cell,
At the extremes, a PV panel provides max V, min A (light load)... or max A, min V (heavy load). You get max power at some middle load setting. To model this behavior, I have never seen a simple method. A normal role for a PV panel is to charge a battery, say from 10.5V (empty) to 14.5V (full). Therefore a reasonable model is a 22V source, (...)
If you have buttons on the steering wheel to activate a radio transmitter then it will need to be powered from a battery that will frequently need replacement. The relay might need a transistor to drive it and a radio receiver must be used activate the transistor.
I can't see the model number of the Kenwood car radio but it probably produces about 14W into 4 ohms at clipping per channel when the car battery is charging from the alternator at 14.4V. With your 12V supply its outputs will be 12W. It probably has 4 channels and is about 60% efficient so the total output from 4 channels is 48W and the heating is
Why not use a rechargeable battery that holds its voltage high until it is almost dead? A Lithium cell is 3.2V or 3.4V when dead and is 4.2V when fully charged. A capacitor voltage begins steeply dropping immediately when it is discharging.

Cell "strength" might be considered as as State of CHarge and Effective Series Resistance (ESR). ESR rises as SOC drops near end of charge and also ESR rises with age or gets "weaker" Each battery chemistry and supplier quality has its own "strength" model Generally Drive Current will be limited by SOC, Ah capacity and ESR from the Datasheets.
First opamp is compare voltages from shunt and current regulator resistors, second - from sawtooth generator and RC chains at output of first opamp - when sawtooth voltage level be more than voltage on capacitor at output of first opamp output of second opamp be high and scr is open. Thereby the angle under which this thyristor is opened depends fr
did you try removing the battery for a few minutes, and then re-inserting?
I want to simulate (and design) an antenna for 2.4GHz Active RFID in CST microwave studio. There is a button cell near the antenna. Most area of the outer case is anode, that is, the power, not the ground. So I wonder how to model it in simulation software. Is it OK to simply create a metal cylinder? Or the battery is something mysterious in mic
I've seen a smaller 2-wire version of this as a battery connector on one of our cordless phones (a larger, outdated model). The matching connector encases the connector in your photo. It has grooves in the sides, to grip the ridges shown in yours. The pins are square although the openings are rectangular. I guess that describes half the header con
Some electric model airplanes use servos that operate rudder, elevator and ailerons at low current from a 3.2V to 4.2V Li-Po battery. They use a pager motor with a pinion gear and it drives a worm gear. There is a potentiometer that feeds back the position if you need it. The servos are inexpensive and available at many hobby stores.
Hi I have a model vehicle that takes a 12v FM1212 brick sealed-lead-acid battery with F1-terminal contact. Is there a Li-ion replacement available in the same form factor? If the voltage is slightly different than it is not a problem, for example 10V-16V would be OK. My problem is that when I am not using the model for 3 months or (...)

Hi I'm trying to get a Simulink model for Bidirectional DC-DC converter to be used for battery charge and dis-charge through a dc bus, the control strategy used is a two-controller control; one is for generating the reference current and the other one is for control the voltage, so the battery is controlled to charge when there is (...)
A capacitor is a simple way to model a battery. Say 1000 F. The time step might need to be increased to suit. Since a battery has internal resistance, put a few tenths of an ohm inline. Since a battery will self-discharge, put a resistor across the capacitor (say 470 ohms). When we compare charging curves, the capacitor (...)

I have a simple non rechargeable battery of 3.6V. Is there any way to confirm that how long it can provide backup. I have heard that the battery can provide backup upto 5 years. How can i confirm that it will really give backup for such a long time
Removing the battery won't work on my HP Elitebook. It has some serious security and encryption stuff in it. I'm not sure that even the manufacturer could reset it, which would generally be the case. It would probably need the security chip desoldering and replacing. I've just checked and HP's answer for my laptop is to replace the motherboard!
The behaviour will be different for a voltage source with true current limiting (e.g. a lab power supply) or a source with internal resistance. You didn't clearly say which model you're assuming. A new battery has most likely a lower internal resistance and delivers a higher current. In so far it's not clear what you mean with the new (...)
