- 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
- charging - Is it possible to convert a USB Legacy charger to support . . .
It will just make much more sense to buy a Type-C PD charger if your devices support it, rather than still dealing with the problem of which USB adapters you can use to convert to Type-C and to which voltages - e g a 45W charger can output 3A at 15W but it can alsp output 20V but up to 2 25A so that your devices can request the best possible
- 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
- 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?
- lithium ion - Why charging Li-Ion batteries in cold temperatures would . . .
Accordingly to what I've found in several sources (user's manual of electronic devices, various forums, e t c ) I shouldn't charge my Li-Ion batteries in cold temperatures because this would harm t
- Lead acid battery boiling during charging: this is bad, right?
I'm an electrical engineer who could use some help understanding lead acid batteries I recently bought an old motorcycle and charged the battery on my trusty automotive style battery charger afte
- lithium ion - If Li-Ion battery is deeply discharged, is it harmful for . . .
Yes, it is dangerous to attempt to charge a deeply discharged Lithium battery Most Lithium charger ICs measure each cell's voltage when charging begins and if the voltage is below a minimum of 2 5V to 3 0V it attempts a charge at a very low current If the voltage does not rise then the charger IC stops charging and alerts an alarm
- Understanding LiPo charging protection circuit - Electrical . . .
The charging cycle for lithium ion batteries can be quite complex, especially in the case of multiple cells in series, but typically involves 4 basic steps: Read voltage, if lower than a certain value (typically 2 8V or so for Li based cells) then begin trickle charge until cell reaches safe charging level, doing this avoids damaging the cell
