Kuv tau siv lub charger tsis zoo rau Li-Ion hlwb tau ntau xyoo. Tias yog vim li cas kuv xav tsim kuv tus kheej, uas tuaj yeem them thiab tso tawm Li-Ion cov cell. Ib qho ntxiv, kuv tus kheej lub charger yuav tsum muaj cov khoom siv uas yuav tsum qhia qhov hluav taws xob, qhov kub thiab lwm yam ntaub ntawv. Hauv qhov kev qhia no kuv yuav qhia koj yuav tsim koj li cas.

Khoom siv

Txoj haujlwm no muaj cov hauv qab no:

• 24 x 90Ω resistor (THT)
• 1 x PCB
• 3 x Pin 4 pin
• 13x Transistor (THT)
• 1x Pin header 3 tus pin
• 4 x Diode (SMD)
• 1 x Joystick (SMD)
• 34x 1KΩ resistor (SMD)
• 10 x 100Ω resistor (SMD)
• 6x 1, 2KΩ resistor (SMD)
• 3 x 10KΩ resistor (SMD)
• 15 x LED (SMD)
• 3 x RGB LED (SMD)
• 1x Ntxuam +12V 40mm x 40mm x 10mm
• 1x ATMEGA328P-AU (SMD)
• 1x Mini buzzer (THT)
• 1 x DC fais fab tuag
• 1 x Pin jumper
• 1 x DC-DC buck converter (THT)
• 1x USB 3.1 nkaus (SMD)
• 16x Pin header txiv neej
• 1x I2C oled zaub (THT)
• 2x 16MHZ siv lead ua (SMD)
• 1 x USB-B (SMD)
• 6x Li-Ion tus nqi tswj (SMD)
• 1x USB maub los
• 1x Khawm (SMD)
• 12 x 8µF cap (SMD)
• 4x 0, 1µF cap (SMD)
• 6x 400mΩ resistor shunt (SMD)
• 1x I2C temp sensor (THT)
• 3x Shift register (THT)

Ib qho ntxiv, koj yuav tsum muaj cov khoom siv ntsuas kom haum thiab ntsuas ntsuas, uas suav nrog cov hlau txuas, cov laug, (cov khoom siv cua sov), ntau qhov ntsuas thiab lwm yam.

Cov software hauv qab no tau siv:

• Autodesk EAGLE
• Arduino IDE Cov
• 123D Tsim

Koj tuaj yeem nrhiav cov ntaub ntawv ntxiv hauv qab no txuas: github.com/MarvinsTech/Battery-charge-and-discharge-controller

Kauj ruam 1: Soldering

Ua ntej koj muab tag nrho cov khoom sib txuas (zoo li hauv cov duab) ntawm lub rooj tsavxwm, tab sis nco ntsoov tias cov khoom siv SMD tau muab muag rau hauv qhov raug. Koj tuaj yeem paub qhov kev qhia raug los ntawm cov kab dawb nyob ntawm lub rooj tsavxwm. Thaum koj tau ua tiav cov khoom siv dag zog, tsis txhob nyob hauv ib qho xwm txheej twg txuas rau lub rooj tsav xwm hauv Circuit nrog tam sim no, vim qhov no tuaj yeem ua rau puas lub Cheebtsam!

Kauj Ruam 2: Kev npaj rau Kev Ua Haujlwm

Txhawm rau kom muaj peev xwm ua haujlwm ntawm lub rooj tsavxwm nrog qhov xav tau tam sim no, peb yuav tsum xub teeb tsa DC rau DC hloov pauv mus rau qhov hluav taws xob tso tawm ntawm +5V. Txhawm rau ua qhov no, peb xub rub lub +5V jumper ntawm lub rooj tsavxwm thiab tom qab ntawd txuas nws mus rau lub zog ntawm DC nkaus. Nco ntsoov tias qhov hluav taws xob nyob ntawm thaj tsam ntawm +6V txog +12V, txwv tsis pub ua rau DC rau DC phaw hloov pauv tuaj yeem tshwm sim. Tom qab ntawd ntsuas qhov ntsuas hluav taws xob ntawm qhov hloov pauv (saib daim duab) thiab tib lub sijhawm teeb tsa kwv yees li ntawm +5V nrog tus ntsia hlau. Yog tias lub ntsuas hluav taws xob yuav tsum tsis muaj qhov hluav taws xob, nyem qhov hloov ntawm lub rooj tsav xwm hauv Circuit kom muab DC rau DC hloov pauv nrog lub zog.

Thaum koj ua tiav, koj tseem tuaj yeem txiav ib qho txhuas lossis hlau phaj thiab muab tso rau ntawm qhov tiv thaiv nrog cov cua sov. Los ntawm qhov uas cua sov tuaj yeem tawg tau zoo dua. Txawm li cas los xij, Li-ion cells nrog cov hnub qub tiv thaiv no tau tso tawm ntawm thaj tsam 220mA. Uas txhais tau tias cov neeg tawm tsam tuaj yeem ncav cuag qhov siab tshaj 60 ° C lossis 140 ° F raws li kuv ntsuas. Tias yog vim li cas kuv xav tias qhov no tseem tuaj yeem tawm mus.

Kauj Ruam 3: Tshaj Tawm Txoj Haujlwm

Hauv theem kawg koj yuav tsum txuas lub rooj tsavxwm mus rau lub khoos phis tawj ntawm USB hom B txuas thiab ntsaws tus lej nrog qhov hloov tshiab kawg ntawm nws. Txhawm rau ua qhov no, xaiv Arduino Nano hauv Arduino IDE hauv Cov Cuab Yeej -> Pawg Thawj Coj thiab ATmega 328P (Laus Bootloader) hauv qab cov khoom Txheej Txheem. Tom qab ntawd nyem lub pob rub tawm thiab koj tus kheej lub roj teeb them thiab cov tswj kev tso tawm yog npaj txhij.
