- How to Calculate the time of Charging and Discharging of battery?
Charging of battery: Example: Take 100 AH battery If the applied Current is 10 Amperes, then it would be 100Ah 10A= 10 hrs approximately It is an usual calculation Discharging: Example: Battery AH X Battery Volt Applied load
- charging - USB-C power negotiation - Electrical Engineering Stack Exchange
For negotiating the power, USB C has an passive and an active standard Passive method With the passive standard, you use your microcontrollers ADC to read the voltage on both CC pins, and take the highest voltage (make sure to properly deal when VBUS is not yet active, so use a 22k resistor to prevent the microcontrollers ESD diodes from affecting the connection test from the charger)
- How does a USB C port provide the power to charge laptops?
Coupled with higher voltage, that gives a lot higher charging power All in all, I guess that the laptops will as well charge with 5V (on USB A charger), just far slower And based on what I saw from Apple for their new Macbook, the charger is 29W, so most likely a Profile 3 (a bit under spec), it seems then to be only 12V
- How can charging current be understood intuitively?
If one of the phases shorts to ground causing a ground fault, the charging current for the other two phases will flow through the ground fault (2) " Apparently the way to directly measure charging current in small ungrounded systems (in which the charging current value is under 10 A) is to short one of the phases to ground and measure the current
- Why is it that for most Bluetooth audio devices, you cant use them . . .
The other scheme is direct charging where the battery and system are tied together When the battery is too low to run the system during charging, the system can't operate Often, the system is just locked out until charging is complete so the charging current can be properly regulated
- voltage - How does charging a phone battery work? - Electrical . . .
There is a charge controller chip inside the phone that determines how much current to put into the battery Generally lithium ion batteries are charged with a constant current until the cell voltage reaches a specific level, at which point the charge controller switches over to constant voltage charging until the current drawn by the cell decreases to ze
- batteries - Simulating a charging battery in LTSPICE - Electrical . . .
How would I go about simulating a charging battery in LTSPICE? I've seen these two articles ( A Tutorial on Battery Simulation - Matching Power Source to Electronic System and Accurate electrical battery model capable of predicting runtime and I-V performance ) but the models there seem to be more geared towards circuits that are currently
- Charging lead acid batteries in series - Electrical Engineering Stack . . .
When charging them separately, I use a bench power supply with current and voltage control set to 14 1 V So, when charging them in series I would set my power supply to 28 2 V, but then one of the batteries starts gassing and when measuring the individual batteries I see a voltage difference of about 0 3 V
