In this post we discuss the construction of a simple emergency charger pack using Nicket Cadmium (Ni-Cd) batteries for your cellphones and smart phones for emergency charging of your cellphone, so that next time you are never stuck on a highway with a full discharged dead cellphone battery.
电路概念
经常发生这种情况,我们的手机在重要的对话中间就进入了低电池状况,甚至在我们旅行或位于没有可用充电设施的某个偏远室外位置时发生的情况更糟。
无论如何,这个小包装都会使您的手机立即重新填充,每次倾向于在户外平坦。
我们都知道,在3.7 V DC时,手机电池被认为是充满电的。
为了在上述级别充电,充电源需要为放电手机电池提供约4至5伏的电压。
由于在这里我们讨论了从一个电池到另一个电池或从某种电源到手机的能源传输,因此我们需要有某种可以收取的电池组,该电池组将产生所需的4伏,并且可以随时用于充电只需将两者集成在一起,只需将平面手机集成在一起即可。
The above emergency battery pack can be very easily made by putting four Ni-Cd cells in series.
Let's learn how to do it.
您需要的材料
它并不困难,你需要四个1.2 v倪-Cd AAA penlight cells, a four cell holder assembly and a 1 Ohm 1 watt resistor.
如何构建手机电池库
The above holder would generate a voltage of about 4.8V at its wire terminals with four AAA 1.2 Ni-Cd attached to within the given slots correctly.
The 1 Ohm resistor can be connected at the center of the red wire by cutting the red wire at the center and bridging the resistor terminals such that it comes in series with the red wire. The resistor should covered under a plastic tubing or sleeving.
上面组件的红色和黑色电线应用合适的手机充电器销终止,以便可以在需要时轻松地将其插入手机充电插座中。
现在,让我们学习如何在家中充电上述紧急电池组。
使用C/10速率的恒定电压充电器可以安全地将Ni-CD细胞安全地充电约10至14小时。非常有用的7805电压调节器IC可以在此处使用Ni-CD电池组充电。
下图显示了一个非常简单的Ni-CD充电器电路,可用于为上述电池组充电,以使其保持待机位置,并且可以以紧急手机充电器单元的形式在户外进行。
AAA cells are rated at 800mAH
是的,它仍然会收取它,
使用Ni-CD类型的细胞。
您可以采购现成的12V直流管窒息,该管子设计用于使用12V电池操作,并通过12V AC DC DC适配器为它们提供动力,这样您就可以用220V AC Suppy驾驶它们。
you may have to try bigger cells, AAA may not have the capacity of charging 1600mAH cell.
monitor the voltage of the adapter cells while it's charging the cell phone, if it drops quickly (below (3.9V) would confirm the cells inability…..
why we can use the 1 ohm resister
for limiting the current to some good extent.
尽管不建议您将它们串联连接起来进行充电,因为参数对于如此低的AH电池并不那么关键。
输入可以为12V,但为500mA。
一旦充满电,它只能一次恢复一次破败的3.7V单元。
Sir, any other values of resistors can be used? instead of 1ohm 1w & 5ohm 1w??
A 4.7OHM 1W可以使用B而不是5?如果是这样,请给出其他任何值…
罗希斯,可以尝试其他更接近的值,但不应该太大
Please sir, if i use 1uf 25v Electrolytic capacitor, do i ignore the polarity?
您能否表明我如何识别变压器的主要和次要方面。我已经得到了该电路的所有组件,但是在识别主要方面遇到了问题。变压器配有两组绳子:在脚拧紧的脚下,对面有两个黑色绳索和两个红色。
And is there a way of testing transformers?
Please i would appreciate urgent reply as i am very eager to build as my first DIY project.
for electrolytic capacitors the positive will connect with the positive line and negative with the negative line.
检查各个绕组的电阻……具有较高值的绕组将是电源输入的主要电阻,而较低的绕组将是输出。
hi sir, do you have schematic for an adaptor for digital camera? I lost the original adaptor of my BEAC digicam and I want to make a replacement particularly with -3.7V, 0V and +3.7V output to be powered from wall socket.
嗨,你,
您可以使用LM317/LM337 ICS,Google IT制作双重可调电源电路,您会发现很多。
根据您的要求设置电压,并将其用于应用程序。
hello this one is good
hai先生,我经常访问您的网站,真是太好了。我只想在此紧急巡回赛包中提出一个疑问,即“ Ni-CD是可以补充的,或者不可充电。”。请尽快回复我。
Hi Karthick, thanks for visiting my blog!
是的,Ni-CD单元格总是可充电类型,并且在完全放电时需要充电
hai sir can i make a simple inverter circuit for my home with in 500 rupees
在500卢比时 - 不可能构建合理尺寸的逆变器电路
感谢您的回复,先生。我如何在我的家中使用交流电源向这些单元充电。
该电路已在上述文章的末尾提供,请检查。
谢谢你,先生。我买了这个CKT先生,它运作良好。但是我的问题是,如果细胞排出
您可以将其连接5至6个小时,以使电池充满电。
谢谢,先生,我可以将面包板用于充电电路吗?
你可以试试。
Thanku sir once again. I wank to ask one question sir,that is can i make solar inverter with very low budjet like 500 or 600
Karthick, It is possible without solar panel and battery, you can buy a cheap Chinese inverter and check how it was possible for them to make so cheaply.
Please tell me about 4V Dc To 5V converter.
您好,最后一个电路表示为充电器………………………………bt如何知道单元充满了充电的任何指示,我们可以添加到电路中
Hello Basit,您可以与5欧姆电阻并联的1K电阻添加LED……只要电池充电,它将保持照明,并且随着充满电的充满电
Thanx sir
hello Sir,
我想知道,我可以从5V移动充电器收取单个NICD 1.2伏电池。
hello Muhasin, you can do it by employing the following circuit and the mentioned modifications:
//www.addme-blog.com/2012/08/simplest-dc-cell-phone-charger-circuit.html
replace the output with your battery terminals, input supply from charger, replace 9V zener with 3 1N4007 diodes in series ….but cathodes pointing towards the ground line.
并将220电阻变成1K
Sir,can i use this charging circuit for charging Alkaline Batteries?
Mehran,您可以将其用于充电所有类型的电池,只需确保在达到全额充电水平后立即关闭电源即可。
你好先生
I have 3. 7 v battery i want to make a power bank can you please tell me how do i make it i also want a circuit diagram
Thanks
先生,我有2 18650 2200mAh细胞,我想为我的Android收费。5V@1AMP我应该如何使用2-3个组件进行任何简单的电路
you will require a 5V/2amp adapter for this, without an adapter charging cannot be done.
hi SWAGATAM , how can i modify that circuit to charge a 9.6V Ni-cd battery pack
Hi Davis, you can do it by replacing the 7805 IC with a 7812 IC
尊敬的先生
我需要4200mA聚合物电池充电器电路3分钟后至少20%快速充电
我尝试了许多电路,但是所有电路组件都非常热和刻录额度。
我尝试5V put和3A充电电路,这3分钟充电正常,但所有组件都不同。
我的电子邮件ID-giashsmart@gmail.com
亲爱的Giash,脂电池通常需要一个巴拉nced type ofcharger, what is your exact requirement? please specify.
Hi Swagatam,
Can I use nokia BL5C battery
(3.7V-1020mah)作为电力库以充电智能手机吗?
you will need two of those in series, and a calculated resistor in series at the positive while charging the smart phone
Sir can I use this circuit for charging my 3000mah battery
提前致谢…。
Abhijit, you can use the 7805 circuit for charging your 3AH battery but it will be quite slow…
Sir what is the output ampere and voltage of this…
voltage is 5V, and the ampere depends on the value of the resistor.
without resistor it's around 1 amp
Sir can you give me a circuit according to my requirements … Please…..Sir..
Abhijit, make a LM338 circuit and supply 12V/2amps, adjust the circuit at 5V and then you can use it for your smart phone.
先生,您可以给我一个电路,该电路的输出1.5-2.0安培和5V,以给我的3000mAh电池充电2次……请…
提前致谢…
Abhijit,您可以制作以下电路…。一定要用LM338替换LM317,否则您可能不会超过1.5安培
//www.addme-blog.com/p/lm317-calculator.html
接下来,从软件中计算R1,R2以在输出中获得5V,然后您可以将其用于目的
先生,下午好。
Thanks for the site and tips.
Could I use a single 1800mAh cell phone battery in a joule thief to power a cell phone via usb?
Because I have 6 v, but I can not even charge another battery of 3.7 v and 1000 mAh?
请帮我
谢谢Marcelo,您是说您想使用Joule Thief和USB连接器通过1800mAh电池充电手机?实际上,这将取决于手机,当我尝试时,我的手机每次尝试连接电线时都不会因电压掉落问题而接受费用。因此,最好使用两个单元格而不是一个单元格,并使用7805来调节输出为5V,如下所示:
//www.addme-blog.com/wp-content/uploads/2019/05/power-bank-circuit.jpg
感谢您的关注和回应。
我尝试了一个模量XL6009 DC电流连续提升雄鹿可调节的步骤,我能够为手机和另一个锂离子电池充电。
我用陶瓷电容器103和一个1k电阻器在输入中制作了焦耳小偷,一个环形(2×12弯),尖端31c,二极管1N5148和电解1000UF / 25V,甚至还无法再充电,输出为6V。
Could you change this setting to try loading?
您能告诉您在上述模块中使用什么供应输入?该模块具有特定的IC,因此输出将非常有效。12转是相当小的……至少尝试20圈并检查响应……并在1000UF之后使用7805 IC进行稳定。就我而言,电池不足以维持智能手机充电电流……如果可能的话,我会尝试使用更大的电池作为输入并检查响应。
我了解XL6009。它根据要求调整输出。正确的?
我使用了3.7V和1200mAh锂手机电池,标记为4.2V。
我的问题是失去对电池供电的电池充电。
坦克
好的!没问题,只需考虑是否需要向您发送一些照片或电路设计。你可以在这里做吗?
Can you help me. I live where there is no electricity grid in Brazil. For almost 4 years with the limitation of electricity by not knowing the electronics. You are looking to learn and sell in alternative alternatives, but I have the financial limit.
Generally available from a stationary 12v / 12Ah battery and some 3.7v Lithium batteries. Fueled by a 12v / 20w solar plate, mini 12v hydroelectric generator and I’m trying to make a three-phase wind turbine and other small ones with printer motors.
All knowledge and help are welcome.
Do you have an email that I can share some of your knowledge and remove some doubts?

马塞洛(Marcelo),我会尽力为您提供帮助,但我希望在这里通过评论在这里讨论它,以便其他读者也可以从我们的对话中受益。
