How to Make Automatic 12V Lead Acid Battery Charger Circuit Board

Get 10pcs PCB boards for $2 & Big Shipping discount on First order: https://jlcpcb.com
In this video, I will show you how easy it can be to design your own Automatic 12V Lead Acid Battery Charger Circuit Board and have them manufactured professionally at https://jlcpcb.com JLCPCB is the largest PCB prototype enterprise in China and a high-tech manufacturer specializing in quick PCB prototype and small-batch PCB production.

You can use this circuit to charge12V 1A ~ 12V 7A Battery.

List of Components:
R1,R3 = 1K https://goo.gl/4XW5DR
R4,R5 = 1.5K https://goo.gl/V1jUMS
R6 = 10K https://goo.gl/RVB6fy
R7 = 1.2K https://goo.gl/7pZQ96
R2 = 1R5W https://goo.gl/Yq1ouh
PR1 = 50K https://goo.gl/S94qgc
Q1 = D882 https://goo.gl/VbDHWe
D1 = 1N4732A https://goo.gl/2hcQtB
D2,D3,D4 = 1N4007 https://goo.gl/CqfNDo
Relay = 12V https://goo.gl/t87Jg3
U1 = LM7815
5MM LED = Red,Green,Blue,Yellow
Alligator Clips = 2
Jumper = 1 https://goo.gl/1xS713

I designed this circuit to charge your battery @ 70% to 75% only due to some safety reasons. If you want to make it for 100% charging, then remove the LM7815 and connect directly 18VDC supply and set tripping point at 15.8 ~ 16V. and always use 5 to 6 times lower charging current from the maximum value of battery current. i.e 1.2A for a 7AH battery.
*This circuit Has not any current limiting feature.(except 1R5W Resistor)
**This circuit is not 100% Perfect, but it is still very useful for hobby/DIY projects.
***Make it at your own risk.

Read today’s show notes on https://www.evnewsdaily.com


Good morning, good afternoon and good evening wherever you are in the world, welcome to EV News Daily for Tuesday 9th October 2018. It’s Martyn Lee here and I’ve been through EV story today so you don’t have to.


Thank you to MYEV.com for helping make this show, they’ve built the first marketplace specifically for Electric Vehicles. It’s a totally free marketplace that simplifies the buying and selling process, and help you learn about EVs along the way too.


Thank you to yet another Patreon Producer. You are a legend MAXWELL MERGET.



In the U.S. NHTSA has released it’s findings in the probability of injury for those involved in a Model 3 acccident and it’s the lowest score they’ve ever awarded. Apart from driving around in a tank, you’re safest in a Model 3. Tesla explained: “NHTSA tested Model 3 Long Range Rear-Wheel Drive as part of its New Car Assessment Program, a series of crash tests used to calculate the likelihood of serious bodily injury for front, side and rollover crashes. The agency’s data shows that vehicle occupants are less likely to get seriously hurt in these types of crashes when in a Model 3 than in any other car. NHTSA’s previous tests of Model S and Model X still hold the record for the second and third lowest probabilities of injury, making Tesla vehicles the best ever rated by NHTSA. We expect similar results for other Model 3 variants, including our dual-motor vehicles, when they are rated.” “In addition to its near 50/50 weight distribution, Model 3 was also designed with an extremely low polar moment of inertia, which means that its heaviest components are located closer to the car’s center of gravity. Even though Model 3 has no engine, its performance is similar to what’s described as a “mid-engine car” due to its centered battery pack (the heaviest component of the car) and the fact that Model 3’s rear motor is placed slightly in front of the rear axle rather than behind it. Not only does this architecture add to the overall agility and handling of the car, it also improves the capability of stability control by minimizing rotational kinetic energy.”  


Liam Denning has been taking a look at the announcement from Audi that Amazon will install charge points at home for it’s customers: “The oil industry has long been more concerned with generating supply than encouraging demand—why bother, when drivers had no alternative? The hassle of charging has long been one of the things holding back the electrical vehicle market. Amazon’s entry will make that a whole lot easier, potentially representing a major threat in oil’s biggest market.” according to Bloomberg: “The fossil fuel industry should be worried about a company such as Amazon encroaching on its territory. Back in the summer of 2008, three of the world’s five most valuable companies produced oil and gas. Exxon was No. 1. Today, four years after a global collapse in oil prices, Big Tech dominates and Exxon struggles to stay in the top 10.”  




No! No! No! A new article by Fast Company is typical of so many I see and it totally misses the point that EV’s are a change of habit, a change of how we *think* about fuelling personal mobility. They say: “In the not-too-distant future, your local gas station may have chargers for electric cars near the gas pumps. Gilbarco Veeder-Root–one of the largest suppliers of fuel dispensers to gas stations–just invested in Tritium, an electric vehicle charging company.”  



On Toyota RAV4EV owners was fed up with the range and took it into his own hands: “This enthusiastic owner wanted to increase the range of his Toyota, and built this simple trailer solution to double his battery capacity, nearly doubling his range, despite the trailer’s extra 454kg.” according to Gizmodo: “The trailer retains the original Toyota floor pan casing, making it likely as safe as it would have been bolted into the Rav4 body. I’m not convinced that high-voltage cables should be hanging out in the wind as seen in the connection between the trailer and the car, but everything in life is a calculated risk, right? What’s the worst that could happen?”
