I am building a similar setup but rather than using lots of "mains to 5v" psu boards, I have a 100va toroidal transformer, to which I am adding multiple extra secondaries each of which feeds a tp4056/dw01A board via a small bridge rectifier and reservoir capacitor at the input. The number of turns required is easily determined with an ac voltmeter - aiming for at least 3.2 to 4vac to give 4.5v to 5.5v dc into each tp4056. This way you only have to deal with one AC mains connection into the toroid. Each new secondary/rectifier and tp4056 board remains separated from the others except at the lithium ion battery of course, where the outputs of the tp4056 connect in a series string.

[@stelic9515]

thanks alooot. I tried before with dc-dc converters with cc-cv function but didn't work because I connected them in paralel to a single dc source. I think before perhaps connect each dc-sc module to a separate ac-dc power suply to isulate them might work but I didn't try. Now I saw is working! I think can also dc-dc converters with cc-cv can be used . With that can adjust voltage to 4.1 to increase cell lifespan and also amps.

[@eideticgoone7035]

@@tedhancock68 When you have batteries connected in series, the negative terminal of each successive cell will be at a higher voltage relative to the most negative cell. In order to prevent current from flowing backwards into a chargers from cells at a higher relative voltage, the negative terminals of the chargers connected to that battery need to have each charger in series to achieve a higher potential voltage and prevent this backflow. Since it is just the relative difference in voltage between successive pins that determines the charge rate, it does not matter where you plug in the battery balance leads in his 20 pin connector. Without series connecting the charger outputs, you will certainly blow up the chargers that have a high voltage applied to their outputs. I've done this so I know.

With the TP4056 in series you can only connect cells that are in series. If you have one pin feeding 8.4V to one battery and another pin feeding 4.2V to the other battery and they are both in parallel what will happen: Batteries in parallel equalize and if the protection circuits do not work correctly (assuming they won't in series) then you'll charge both cells to 8.4V

@@EVCustomsCustoms have you tried using a different resistor for the amperage? The only issue you might run into or that I can see. You're using 5V1amp PSU. On occasion, some of the TP4056 will try and pull more amperage. If the PSU is only producing .750amps, or under, This might cause and issue with voltages. One fix is to use higher rated PSU or change the resistor that limits the current to equal out the lowest PSU amperage differents. Just a theory. I went with cooling and 5V 2.1amp PSU's. I plan to also add a filter to the AC line before getting to the PSU. Another issue, maybe a dip in voltage. I know here in US we only have 120V, and if you have them in connection with only one line in. It is also possible the PSU at the end maybe producing lower voltages. All of this is just a theory. Maybe I will get a better result with a 10S? Still fun to build....I'll hit you up when Im done

Charging up until the LED gehts blue. Whithout load its normal that the voltage drops to around 4.somethig Volts. Only they shouldnt drop under 4v after some days whithout a load. The simplest way is to get New Batterie cells and Put them in or just Put a Balance cable on the Laptop Batterie pack. A Single tp4056 is enough. I would use it to Charge each individuell Batterie cell fully. Than they should work fine for some weeks... Or just buy a rc charger (Not the cheapest!!!) that can Do Balance Charge. (i dont recommend this if you only Use it for the Laptop. Its too extensive.)

Hi! I did similar project following your video but I have a problem. There's an incompatibility between TP4056 and my BMS. TP4056 is charging the battery over 4.2 V and it's triggering over-voltage protection on BMS. The datasheet says the voltage can reach 4.24 V (4.2 V +- 10%) but I found battery with until 4.26 V. I'm thinking in a way to add an Arduino to cut the power of the TP4056 when the voltage reaches 4.2 V. Best regards.

But if charging the battery "by cells" like he's doing here ends up with all the cells at the same voltage... then isn't the pack balanced? All the "control" is built into each individual TP4056 charging module. The cells that started at a higher voltage did finish sooner and fell to ~4.17V after their charging modules shut off, but I do think that they all would reach the same voltage in the end after they all settle a bit.

[@Tore_Lund]

You can just add a series DC power supply (also isolated, which most laptop size one are) across the string for the bulk charging that works in parallel with the small charging modules. So if you have a 10S string, adding a 38-40V 5A power brick, the batteries will be fast charged unbalanced with 5A total until 3.8V-4.0V per cell. Then the big power supply will stop supplying power when voltage is above its output, and the small 1A modules will do the finishing charge and balancing. You have to have a reasonable balanced pack to not overcharge a few cells with this method, or maybe choose a lower 36V-38V power brick for shorter bulk charging giving you more margin for not overcharging, but this will work. There are different TP4056 modules with 3A output on aliexpress that use 4 TP4056 in parallel on the PCB, but they are more expensive and you'l also need higher current, more expensive isolation PSUs.

You can add as many cells in parallel as you want. Just each cell cuts the 1A by that many cells. 5p = 200mA/cell, 10p = 100mA/cell, 15p = 67mA/cell, etc Using a dual usb charger kinda defeats the purpose. You would incur so much power loss it would be a moot point

@@korishan so how could we boost the amps?

[@Enderkruemel]

@@russelolivarez9320 mostly Not becourse they are the Same Output (the USB plugs are parallel.) it only works if you Use 2seperate!!! USB powersuplys. Otherwise you will get a Short.

Why not use just one ac to dc converter with say 20A+ ?

[@barryrudolph9542]

The individual charger module inputs need to be isolated from each other.

[@fiedag]

@@barryrudolph9542 why is that? Is there not a way to do that without duplicating all that charging circuitly

[@korishan]

The power supplies MUST be isolated as all the TP boards share a common ground. It would basically be a dead short. There are ways to isolate using 1 power supply, yes. But that IC costs at least $5USD for 1. So, if size isn't an issue, better to go with the individual power supplies. You can search for "Power Isolated" on ebay/lcsc/digikey or something to find them. There are ones for $1USD, but they can only do 200mA. To get ones that can do 1A is in the $5USD range

@@radamanthys847 Isso está errado, pois os módulos entrarão em curto. O negativo na entrada é comum ao da bateria.

Why not a single 5V 20A AC-DC? Or 2x 5V 10A? Surely that would be cheaper? And far less wiring with a bus bar.

[@EVCustoms]

How you can charge batteries in series like this?

[@samcs640]

@@EVCustoms replace the 20x AC-DC converters with a single unit and connect the inputs of the 20x charge circuits in parallel. Or am I missing something?

[@EVCustoms]

@@samcs640 ;) You cannot do this, like this you will short all batteries, all your negative GND wires will be same.

[@samcs640]

@@EVCustoms why does it matter if the input side of the charge circuits are connected in parallel? Are the input and output not isolated?

@@samcs640 No is not isolated, all GND wires are same wire.

What is the charging time of the battery????

[@EVCustoms]

This depends from your battery capacity..

[@Enderkruemel]

If the Batterie capacity is 1A it takes 1h If it is 2A capacity it Takes 2h For 8a it takes 8h... But it is Not for fast charging, its for Balancing the Batteriepack.

NEVER USE DW01 CHIP IN SERIES!!! Look up the DW01 sheet: Its on the TP 4056 board. Little bug like chip. NOT MADE FOR SERIES AND WILL CAUSE CASCADE FAILURE. READ: FIRES. ( cause of the Hoverboard pack recalls).

[@GTrainRx7]

It isn't a balance charger per se, just a charger that stops charging each parallel set of cells at the top voltage.

[@Enderkruemel]

Its Balancing works by getting up the voltage to the Maximum for each cell. So all cells are at 4.2v each. Than the pack is Balanced.

[@carboncomplex]

it is very much a balance charger - it just does so in an unconventional way

[@GTrainRx7]

@@carboncomplex On revision of the video... No, it is a charger with a cutoff, it doesn't take input from any other cell in the battery, so isn't "balancing" the cells, it is charging the cells.

[@carboncomplex]

its method of balancing is to cut the cell charging when it gets to the required voltage - this is balancing the cells it is achieving this in a different way but it is definitely balancing - it is not "active balancing" but passive balancing

[@GTrainRx7]

@@carboncomplex "Balance", by definition, requires more than one. This charger does not check any cell against any other, thus is is NOT a "balance" charger. The definition is in the name, literally. What you made is a smart charger.

[@korishan]

At 19:25 you can see how inaccurate this system is. Cell 1 is 4.21 and cell 2 is 4.17V to start off with. They have stopped charging. So therefore, the cells are not "balanced". Going further along the timeline, you can see the cell voltages drop. You can't rely on cell drop after discharge to bring cells into balance. What if these were immediately put into service after charging? They would start to drift out of balance quickly. TP4056 ICs are rated with +/-1% variance, which is 4.242V - 4.158V. I would not recommend using these boards for this type of application. They are great for 1s charging. The TP5100 is even better as it can do 2A output Nice idea, and shows that you need isolated power. But in all practicality, it's not, well, practical.
