Step 9: Charge controller circuit diagram

Purpose of the charge controller circuit is to cutoff the supply from the solar panel when the battery is fully charged to avoid over charging... and to start charging when battery voltage drops off a certain value... in my case the max. allowed voltage is 13.7volts and min is 13volts.
<p>I want to make one !!! </p>
<p>so! cool!</p>
How much weight can this move?
<p>Hi !</p><p>I&acute;m very interested on aqcquiring the instruction plans of this vehicle and would thank very much who inform me about it.</p><p>Thanks !</p><p>Luiz</p>
<p>great job. :) will you send the charge controller circuit diagram and all the details in jrlavina27@yahoo.com thank you very much :)</p>
<p>hie great stuff,am doing almost similar project........can you send me charge controller circuit design at knkonjela@yahoo.com</p>
<p>thank you for this wonderfull project</p>
hi nice project. I was wondering about the acceleration. isnit just on of or and accelkeration control?
<p>will you send mi 5 watt 6volt solar charger controlar on my mail id?</p><p>my mail id is-future.energy2014@gmail.com/futureacc2014@gmail.com</p>
<p>will you send mi 5 watt 6volt solar charger controlar on my mail id?</p><p>my mail id is-future.energy2014@gmail.com/futureacc2014@gmail.com</p>
<p>Hi! Nice job. Can you please also send me the charge controller circuit diagram. I want to do something similar with a li-ion battery for an electric car project.</p><p>there is my e-mail: ulrichmabou@gmail.com</p><p>Thanks</p>
Wow very impressive. i work at a machine shop and i want to build something like this. I didnt see any details on your controller though. care to enlighten me?
thanks you so much .... well i just bought it from the local electronic store... its called &quot;Charge Regulator or controller&quot; also called &quot;Cut-off circuit&quot; well it consists of a relay and resistors and IC (dont know the specs) but its purpose is to cutt-off the supply from the Solar panel when batteries are fully charged in my case utt-off voltage was 13.9 Volts
<p>What is amperage of the relay in the Charge Regulator.</p>
IC may be 8 PIN DIP 555 Timer IC.
<p>hi., i want to full details of motor for this projectt., our mail id is arunaveen14@gmail.com, </p>
DOES IT HAVE A SPEEDOMETER OR ELSE HOW DO YOU KNOW THAT IT TRAVELS AT A SPEED OF 30 MILES PER HOUR?
ok firstly i would like to ask you where are you from?... secondly its 30kmph not mph.... and lastly no it does not have a speed-o-meter, yet we can measure its speed!... HOW?.... well we had motor bikes which traveled along with the vehicle .... and they had speedometer!... hope you understand the rest .... cheers
<p>please give the correct info because it is not possible to run a 24 volt DC motor with a 12 volt battery</p>
You tell him ! God, some people....
<p>AOA. Great effort farrukh. Im also from UET but in Computer Science department. Nice to see your work on this website.. Going to rate your work. But please answer that how a 12 volt battery controll a 24 v motor???</p>
will you please send the circuit diagram of 40 watt solar panel charge controller?? my mail id vickydoner90@yahoo.in
farrukh i wanna ask a question which is......if the batrry charg is going down so it affect the speed of the trike or not.....means that if charge is low will it speed be slow and vice versa plz guide me......
Excellent work farrukh!! Very good work here!!
thanks you so much dbonaire :)
Hi! A0a. Farukh i tried the number that you gave. its off. can i contact u in any way. my number is 0333-6670140. i need to talk to you about this project. My name is Aamir
hi farrukh nic projct plz let m inform which components is used in this??
Nice Work farrukh, Pakistan needs Man like you. With 40 Watt Solar panel, 80Ah battery achieving 30mph and covering 70km seems awesome. Keep it up. <br>I want to be your fan, what's your fb ID. <br>
Why don't you buy a donkey instead????
great job dude....... <br>but i want to ask some questions :- <br>1. It is possible to run a 24v dc motor with a 12v battery? <br>2. How much torque is produced by ur motor and at what rpm? <br>3. weight of your vehicle?
Does anybody have any ideas for the motor? <br>
Hi. where i can find this charger controller circuit ?
Dear friend where i can locate the circuit diagram or where i can but the PCB ??
Hi Farrukh, <br> <br>1. If we want to use the same technology and use it as rickshaw / cart to carry construction material, or vegetables, or waste material, how much weight it can carry with present battery. <br> <br>2. Suppose if we want to carry material of 250-300kg as solar powered rickshaw. <br> <br>3. Incase during winter or rainy days, when no solar energy, can we charge the battery through electricity (as as back-up charge). Some solar water heaters come up with both option, solar charge &amp; water can be heated through electric connection also. <br> <br>Regards, <br>Amit
ossum project.. <br>excellent...kep it up..:) <br>hey can you please send me solar panel specifications <br>to my email ritik.saluja@ymail.com
hey can you plz tell the solar panel specs <br>to my email ritik.saluja@ymail.com
Excellent project, very simple and relatively easy to build, I congratulate you, the world needs people like you.
Very cool! Congrats! I am looking to make a trike that uses a scooter motor. Keep up the good work. Steve
Very Good Farukh, i like your idea Good Luck.
Why did you use a 12V battery for a 24V motor?
Hi farrukh,<br>It was a pleasure to know about the project. Actually i was working on the same lines for some months. Now can you please tell me in detail how did you decide the pv pannel specifications n the battery. please mail the calculations to my email id <br>ashis08@rediffmail.com<br>Regards<br>Ashish
thank you so much for the interest Ashish... but i have already provided enough information ... by which anyone can make there own vehicle like this... i can't give you more details and calculations as they are confidential...! Hope you understand.... thanks anyways
Hi farrukh,<br>It was a pleasure to know about the project. Actually i was working on the same lines for some months.

Hello <br>Great job, but how do you stop it
i did not found any content or discription about motor so please will you tell me its detail.
Cool build and congratulations on winning the Green Challenge.
thank you so much dorybob! I'm still surprised!
hi. i want to know that by once fully charged batery how much km it can run. and please tell me whole full discription of motor. motor'shp ,voltage , ampere, type of motor. and you made awesome vehicle.
hi, thank yo so much ...<br>the info you need is written in Step 10.<br>However, it can go upto 70 km in single charge<br>motor is 24V DC, 17amps, makes it half HP<br>Cheers,<br>-Farrukh
Hi. Great to see such a practical vehicle. What are all the battery and motor details?
