How can I control the current that is supplied to a battery? I need to balance current consumption to avoid some parts of the system run out of power.
My system is described in the attached file. I have a 12V input which goes into a Boost regulator to get 48V. Those 48V are used to feed a...
LI charger chips are switching step-down converters with a constant-current mode.
Say it's a single switch buck-type charger. It's input range is 5V to 10V, and is capable of charging cells at 2A.
Will that chip require a 2A input regardless of Vin, whether 5V or 10V?
Or, can the chip accept a...
So I have been working on a wireless charger for EV applications. The prototype I designed uses a control system to manage the voltage at the exit of the charger. Without going too deep, we can just assume the charger is a source supplying a square signal of 15 Volts of 150kHz...
Greetings. A vendor selling TP4056-based 5 V charging modules for Li-ion cells specified the following resistance values and resulting current for selecting the current-programming resistor:
I am writing to ask about how can I control de currents in my inductive charger more specifically the current in the resonant tank I designed.
My goal is to design an inductive wireless charger that uses a resonant tank to maximize the efficiency of the process. I am going to...
I have a question about Li-ion rechargable batteries. I have almost no experience with it. Documentation to battery is very poor, but there is an info about charging profile: Stage 1: Constant Current 0.82 Ampere (0.2C) until Voltage reach 4.2V Stage 2: Constant Voltage (4.2V) with...
I plan to build a high capacity 3.7V/5V solar charging powerbank (something like 10-15ah).
I’m going to use modules of TP4056 breakout board each coupled with two 18650 cells in parrallel.
But I was wondering what would it need to charge two or three of these TP4056 modules with a...
I am totally new to all this and i honestly have no idea what i need so im looking for some advice.
what i want is to be able to make my own circuit board layout for a fast charger plug for your mobile.
what i want to know is:
what components do i need
which components connect to...
