DIY Lithium-Ion Battery Charger-Making And Charging

Batteries play an essential job in any battery worked venture/items. Rechargeable batteries are costly, as you have to purchase battery charger alongside batteries contrasted with use and throw batteries, yet are incredible incentives for money. Battery-powered batteries utilize a few unique mixes of anode materials and electrolytes, for instance, lead-corrosive, nickel-cadmium (NiCd), nickel-metal hydride (NiMH), lithium-particle (Li-particle), and lithium-particle polymer (Li-particle polymer).

Are you curious to make the build charger instead of buying an expensive one? Let's get started.

How do you make a lithium-ion battery charger?

Step 1 - The first step is to gather the electronic components that are required for the Li-ion battery charger.

• · TP4056 based lithium-ion battery charger protection module with battery,

• 12 Volt 2 Ampere wall adapter,

• SPST 2-pin switch,

• 7805 voltage regulator

• 100 nF capacitor (4 in quantity)

• Li-ion 18650 battery holder

• DC jack and,

• general-purpose circuit board.

Step  2- TP4056 Based lithium-ion battery Charger Module

Let's dive into the subtleties of this module. There are two variants of this TP4056 based Li-particle charger breakout board accessible in markets, with and without battery assurance hardware. 

TP4056 is a complete, steady current/consistent voltage direct charger module for single-cell lithium-particle batteries. Its SOP bundle and low outside part check make TP4056 perfect for DIY applications. It can work with USB just as wall connectors. 

For having safe charging of a 3.7 V Lithium-ion batteries, they ought to be charged at a consistent current of 0.2 to 0.7 occasions their ability, till their terminal voltage arrives at 4.2 V, later they ought to be charged in steady voltage mode till charging current drops to 10% of beginning charging rate. 

You can't end charging at 4.2 V since the limit came to 4.2 V is just around 40-70 % of the full limit. This is taken consideration by TP4056. 

Presently one significant thing, charging current is dictated by resistor associated with a PROG pin, modules accessible in the market, for the most part, accompanies 1.2 KOhm associated with this pin, which compares to 1 Ampere charging current.

Step 3 - Connect All Parts

Presently, you should interface electrical parts utilizing binding iron and patch wire to finish the hardware. 

• '+' terminal of DC jack associates with one terminal of the switch and '- ' terminal of DC jack interfaces with GND pin of 7805 controllers. 

• Another pin of the switch is associated with a Vin pin of 7805 controllers. 

• Interface three 100 nF capacitors in equal among Vin and GND pin of voltage controller. (Utilize General reason circuit board for this reason) 

• Interface a 100 nF capacitor among Vout and GND pin of voltage controller. (Utilize General reason circuit board for this reason) 

• Interface Vout pin of 7805 voltage controller with IN+ pin of the TP4056 module. 

• Interface GND pin of 7805 voltage controller with IN-pin of the TP4056 module. 

• Associate '+' terminal of the battery holder to B+ pin and '- ' terminal of the battery holder to Bi-pin of the TP4056 module.

Step 4- Assembling

Assembling the parts - Modifying the Enclosure

Imprint the components of the battery holder on the walled-in area utilizing a cutting edge blade. 

Utilize a hot-cutting edge to slice through the nook according to the stamping of the battery holder. 

After adjusting cut utilizing hot-sharp edge, nook ought to look like. 

You have to make markings of the USB port of TP4056 on the fenced-in area. 

Utilize hot-sharp edge to slice through the fenced-in area according to the checking of a USB port. 

Take the measurement and make markings of TP4056's LEDs on the walled-in area. 

Utilize hot-sharp edge to slice through the fenced-in area according to the checking of LEDs. 

Follow comparable strides to make mounting openings for DC jack and switch

after adjusting the fenced-in area, it gives adequate access to the hardware.

Keeping the electronics inside the enclosure

Supplement battery holder with the end goal that is mounting focuses are outside the fenced-in area; use a glue gun to make a welded joint. 

Spot TP4056 module, with the end goal that LEDs and USB ports are available to structure outside the fenced-in area. No compelling reason to stress if appropriate estimations were made in past advance, things get a fall set up consequently, at long last use glue gun to make firm joint.

Spot 7805 voltage controller circuit; use the glue gun to make a welded joint. 

Spot DC jack and Switch at their comparing areas and again use the glue gun to make a rigid joint. 

Utilize some extra screws and screwdriver to close the back cover. 

Later you can utilize some dark protecting tape to conceal bothersome projections came about because of slicing through the hot edge. (recording is additionally a decent alternative) 

Completed Lithium-particle charger looks. Presently you should test the charger.

What tool do you need when you DIY lithium-ion battery charger?

These are the tools that are required for the DIY Li-ion battery charger

Solder iron, solder wire,

Hot blade (link to my instructable, that help you in making this blade),

Glue gun, glue sticks,

Screwdriver and some screws and,

Plastic enclosure 8 cm x 7 cm x 3 cm. 

Can you charge a lithium-ion battery with a standard charger?

The primary standard of battery charging is that a charger intended for one sort of battery may not be reasonable for charging another. You can't charge a cellphone of a vehicle battery charger, yet neither should you charge NiMH batteries of a nicad charger.

• Numerous modern rechargeable appliances and devices-such things as PCs, MP3 players, and cellphones-accompany their own, uncommon charger when you get them, so you don't need to stress over coordinating the charger to the battery. 

• However, if you purchase a bundle of conventional, battery-powered batteries in a store, it's significant that you are buying batteries that suit the charger you have or replace your charger in like manner. 

• Note the voltage and current that the batteries require (it will be set apart on the battery bundle or the batteries themselves), make sure to pick a charger with the correct voltage and current to go with them, and charge for the right measure of time.

• If you need to get yourself some rechargeable batteries, however, you're not so much sure how to approach coordinating batteries and charger, go for a consolidated set-where you purchase batteries and charger in a similar bundle.

Now go ahead, make a charger of your own.
