обман

00:00:04

Hello friends, today there will be a review

00:00:07

and a few tests, but for this I need to

00:00:10

slightly redo my capacitance measurement tester,

00:00:13

who doesn’t remember, I assembled this tester

00:00:16

from a construction set, then

00:00:18

I redesigned it a little by adding a charging module

00:00:21

on the TP 4056 And today another

00:00:25

rework, the

00:00:27

rework is unimportant, so I’ll

00:00:28

put it in a separate section video there is

00:00:31

no point in the test it works perfectly

00:00:34

you can charge and discharge lithium-ion

00:00:37

batteries but you can only test

00:00:40

18650 banks because the holder is placed

00:00:43

under them And today I will fix it the

00:00:47

solution is very simple, just

00:00:50

install banana terminals on the case and

00:00:53

connect them parallel to the holder as

00:00:56

a result connected to these terminals, the battery

00:00:59

can be charged and discharged, and this

00:01:03

means that it will be possible to measure the capacity of

00:01:05

not only 18650 and In addition, when

00:01:10

installing a battery in a

00:01:12

battery holder, its voltage will be on the terminals; this

00:01:15

can also be used

00:01:18

[music] the

00:01:30

main point for today is

00:01:32

lithium polymer batteries which I

00:01:36

ordered it in order to do something

00:01:39

and convert something to battery

00:01:42

power instead of batteries, but more on that later.

00:01:45

Today we’ll check what

00:01:48

these batteries are,

00:01:50

size 43 by 25 and 10 millimeters,

00:01:54

stated

00:01:56

capacity of 1000 milliampere hour and the most

00:02:00

important question is this the

00:02:02

capacity corresponds to 1000 milliampere hour here Of course

00:02:04

not, but here’s how bad it is Now

00:02:08

we’ll find out how to measure the capacity correctly, you can

00:02:11

only discharge it during charging,

00:02:14

the capacity will be overestimated due to the charging algorithm

00:02:19

[music]

00:02:24

so first of all we charge the battery

00:02:27

to 100 percent before charging starts, the

00:02:30

voltage on the battery was The 3.9 Volt

00:02:34

battery was charged to 4.2 Volts as

00:02:38

it should be

00:02:40

[music] they

00:02:51

will discharge to a voltage of 2.9 Volts with a

00:02:55

current of 1 ampere,

00:02:58

this is even lower than the minimum

00:03:01

discharge voltage for lithium, it is not recommended to

00:03:03

discharge lithium-ion cells below 3

00:03:07

Volts, but after discharge I I

00:03:10

will immediately put the battery on charge;

00:03:14

it will not be stored discharged and in

00:03:16

addition, the influx of charges of 1 ampere

00:03:19

discharge is quite fast and the chemical

00:03:22

reaction does not have time to occur completely,

00:03:24

so when the controller disconnects the

00:03:27

battery from the load, after a couple of seconds the

00:03:30

battery will show 3 Volts and even a little

00:03:33

more,

00:03:35

this is quite normal phenomenon, the

00:03:38

first battery gave 702 milliamp

00:03:41

hours 2,630 3,640 I expected the worst, to be

00:03:48

honest, I thought it would be less than half

00:03:52

[music]

00:03:58

with batteries, that’s all, but that’s not all; the

00:04:05

charge controller board for the TP-5100 has arrived today; this controller

00:04:09

is interesting because, unlike the TP -4056

00:04:12

can charge either one element or

00:04:16

two connected in series; the

00:04:18

charged element can supply 1 or 2

00:04:22

amperes and the operating voltage at the input

00:04:25

can be from 5 to 18 volts;

00:04:28

naturally, the charge proceeds according to the algorithm

00:04:32

accepted or correct for charging

00:04:35

lithium; there is an indication of the charge and its

00:04:39

end except two-color LED

00:04:41

indication on the board there are

00:04:43

contacts for connecting an external

00:04:45

LED the price of such a module is about 60

00:04:50

cents, that is, a little more expensive than the

00:04:52

tp-4056 module at the beginning I planned to

00:04:55

test the operation of this controller on

00:04:58

newly arrived batteries from this in

00:05:01

principle and began the controller clearly sees

00:05:04

completely charged battery and

00:05:06

refuses to charge it further, the charge current at the

00:05:09

output is zero

00:05:19

[music]

00:05:23

we take a half-discharged battery and

00:05:27

now the charge is on, the charge current is 680

00:05:30

milliamps there are several points

00:05:33

regarding this module, it can

00:05:35

supply a current of 1 or 2 amperes to the battery

00:05:38

in order to switch from

00:05:41

two amperes for one you need to unsolder one of the

00:05:44

only setting resistors per one ohm,

00:05:47

in other words, the board comes

00:05:49

configured to charge with a current of 2 amperes, but

00:05:54

there is one pitfall here:

00:05:55

cooling,

00:05:57

almost none of the sellers

00:06:00

indicate that when using the board

00:06:03

in the ampere version of switching on, you need to

00:06:06

ensure good heat removal from

00:06:09

For this chip, you need to glue a radiator on the back side of the board;

00:06:13

this side is a

00:06:16

solid polygon and the place under the chip is

00:06:19

without a mask at all and is laid without

00:06:23

cooling at two amperes; this board

00:06:27

will not work for very long.

00:06:29

However, in my case, I can’t get those

00:06:32

treasured 2 amperes failed

00:06:36

lithium-polymer battery from the review,

00:06:39

not fully charged, took only 0.7

00:06:42

amperes in order for the board to produce 2

00:06:45

amperes, the input voltage must be

00:06:47

higher than 8 Volts on the left, the ammeter shows the

00:06:51

battery charge current on the right, the voltmeter

00:06:54

shows the supply voltage at the input of the

00:06:56

module when the voltage changes at the input, the

00:06:59

output current remains stable on the

00:07:03

one hand, this cannot but rejoice.

00:07:05

But on the other hand, there should be 2

00:07:08

amperes or something like that

00:07:12

in order to eliminate the issue of the

00:07:15

battery itself, I assembled a simple stand with

00:07:18

18650, everything is the same as in the previous one in the

00:07:21

frame on the left is the charge current on the right is the voltage

00:07:25

at the input of the module and still the module

00:07:28

behaves exactly the same as TP 4056. That is, it’s

00:07:31

as if it is configured for a maximum current of 1

00:07:34

ampere

00:07:38

[music]

00:07:47

[music]

00:08:09

there was an assumption that one of the only

00:08:12

setting resistors is open, but two

00:08:14

Parallel resistors of one ohm, as

00:08:17

we are supposed to have, have a resistance of half an

00:08:20

ohm,

00:08:21

for the sake of the purity of the experiment, I tried to

00:08:23

remove one of the resistors, that is,

00:08:26

switch the module to charge mode up to 1

00:08:28

ampere. Well, what if there is some kind of new

00:08:31

version? Although this should not happen, as

00:08:35

expected, a miracle did not happen

00:08:40

[music]

00:08:54

one more point left to check is the

00:08:57

possible charge of two series-

00:08:59

connected batteries, to activate

00:09:02

this mode you need to close two contacts. There is

00:09:05

nothing special in this mode, no

00:09:09

balancing or anything like that,

00:09:11

just the output voltage rises

00:09:13

to 8.4 Volts as and it should be with two

00:09:19

batteries connected in series

00:09:21

[music] the

00:09:28

current in this mode is limited to one

00:09:31

ampere

00:09:33

[music]

00:09:40

now

00:09:42

both devices measure voltage: the

00:09:45

left one is the voltage on the

00:09:48

battery, the right one is also at the input of the

00:09:51

module

00:09:52

and in this switching on everything works fine

00:09:55

by the way with a current of up to 1 ampere the module

00:10:00

does not heat up at all. This is of course very

00:10:02

strange, but I was never able to get a charge of 2 amperes

00:10:06

from this module. I

00:10:07

purchased this module precisely for

00:10:10

the opportunity to connect a battery of

00:10:13

lithium-ion batteries consisting of two

00:10:15

elements for charging, and this mode works normally here; an

00:10:20

interesting effect occurs at the end

00:10:22

charge in 2S mode, the indicator does not just

00:10:25

switch from Red to Blue, but

00:10:28

starts blinking Red Blue Red

00:10:31

Blue and so on, this effect occurs

00:10:33

when two batteries of different capacities are connected to the battery, the

00:10:39

blinking frequency gradually increases and at the end

00:10:41

the indicator finally switches to

00:10:44

Blue By the way, I have a question to

00:10:46

the public Why is the

00:10:49

end of charge indicator blue Previously, it seemed to

00:10:51

always be green a few words

00:10:54

as conclusions the first point

00:10:56

batteries from a thousand milliampere hour

00:11:00

have a capacity of 600-700 milliampere hour This is

00:11:04

of course not in order but expected so

00:11:07

as it is I’ll try to challenge this question

00:11:11

but I’m afraid with mine

00:11:14

I won’t be able to use a capacitance measuring device; the second point is the

00:11:17

charge module on the TP 5100; for some reason the module

00:11:21

was unable to supply 2 amperes to the

00:11:24

battery, although as far as I can tell

00:11:26

this is rather a special case; I bought this module

00:11:30

to charge two series-

00:11:32

connected cans and this mode works

00:11:34

perfectly

00:11:36

in Compared to the

00:11:38

tp-4056 module, this module is a little more expensive; it

00:11:42

does not have any connector on board, but it

00:11:45

is possible to charge two

00:11:47

series-connected batteries at once

00:11:49

and power the TP 5000, which is possible in a

00:11:54

fairly wide voltage range from

00:11:56

5 to 18 volts; the

00:11:59

general terminal is ambiguous in the battery they did

00:12:03

n’t report the capacity, the module doesn’t want to

00:12:06

produce its maximum

00:12:08

and everything seems to be working, but somehow it’s

00:12:11

half-way And that’s all for today.

00:12:14

Subscribe, there will be a lot more

00:12:17

interesting things. Bye everyone
