- charging - USB-C power negotiation - Electrical Engineering Stack Exchange
We designed a power board that can deliver 5V and 3V3 Those two voltages are provided by two boost buck converters that can deliver 3A each The board accepts power from a USB-C socket which is
- 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
- How to Calculate the time of Charging and Discharging of battery?
How do I calculate the approximated time for the Charging and Discharging of the battery? Is there any equation available for the purpose? If yes, then please provide me
- Voltage input for charging NiMH Batteries - Electrical Engineering . . .
I have 12 AAA NiMH batteries(1000mAH and 1 2V per battery) and I want to know what is the optimum voltage for charging them I am using a simple Constant Current charger(LM317 and 68 Ohm Resistor(R
- 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?
The charging current I’m talking about would be the one between un-shorted phases and ground when there is a short to ground in one of the phases in a distribution network or facility I'm not talk
- voltage - How does charging a phone battery work? - Electrical . . .
Cell phone battery charging is handled through a battery charging IC Typically a switching regulator that varies voltage and current in order to charge the battery It also measures battery voltage and temperature to know when to cut the charging, through a mosfet
- How do chargers with different output values work?
In this case if I were to plug in the power bank to my laptop charger how do I know that it's charging at the 15V=3A that it should and not at 20V? On the other hand, if I were to charge my laptop with the same power bank (output: 5V=3A, 9V=2A, 15V=1 2A, same as input) could the power bank be damaged?
