CPS<\/p>\n

I recently purchased the plans for the Capacitive Battery Charger and Transformer and there are some things that I just can\u2019t understand.<\/p><\/blockquote>\n

1. Does the CBC stops loading batteries when they\u2019re full<\/p><\/blockquote>\n

No. \u00a0Most battery chargers don\u2019t. \u00a0You can add that feature using electronics. \u00a0I plan to offer such a circuit when I get time.<\/p>\n

or I have to figure it out by some mysterious ways.<\/p><\/blockquote>\n

Most people who recharge batteries know how to determine if the battery is charged.
\nStop charging when the\u00a0voltage\u00a0is full or peaks, whichever comes first.
\nFor example, a fully charged 12 Volt lead acid battery is fully charged when it\u2019s somewhere between 13.5\u00a0VDC\u00a0and 14 VDC when being charged. \u00a0Once the charger is removed the state of charge shouldn\u2019t drop to less than 12.6 VDC.<\/p>\n

If the battery is sulfated it may go as high as 80 VDC to push one amp across the sulfation. \u00a0As the sulfation dissolves the voltage will drop, to as little as 5 VDC, then the battery will charge normally. \u00a0The CBC\u2019s ability to reach higher voltages (if needed) is what gives it the capability to recharge sulfated batteries.<\/em><\/p>\n

If you charge it above 14 VDC, like to 15 VDC and the voltage starts to drop, stop the charger immediately or battery damage will occur (plates will start to decompose).<\/p>\n

2. What do the symbols DC amp and DC volt (both with arrows) mean (CT, page 1, figure 1).<\/p><\/blockquote>\n

Those are amp and volt gauges.<\/p>\n

3. What does F1 mean?<\/p><\/blockquote>\n

Fuse.<\/p>\n

4. What does the A on the Bridge\u00a0Rectifier\u00a0stand for (CBC, page 3, figure 1)<\/p><\/blockquote>\n

Weird font issue, a typo. \u00a0It\u2019s supposed to say AC.<\/p>\n

5. It says that \u201camperage\u00a0will increase with the increase of capacitance\u201d but it doesn\u2019t say the way how to calculate the increase.<\/p><\/blockquote>\n

There are comments to help you calculate the capacitance needed for amperage.<\/p>\n

The increase may be parabolic or linear.<\/p><\/blockquote>\n

It\u2019s linear.<\/p>\n

In my case, I would like to get 12 VDC and 25 ADC from 220\u00a0VAC\u00a0(European standard). What formula do you use to calculate the capacitance necessary.<\/p><\/blockquote>\n

You\u2019ll get about 1 amp for every 12.5\u00a0uF\u00a0with 220 VAC at 50 Hz.<\/p>\n

Below is a correspondence that corrects mistakes we made when converting the Capacitive Transformer document to it\u2019s electronic version. \u00a0The CT drawing is correct, just in the wrong place; it was put in Figure 1 instead of Figure 2.<\/p>\n

I can no longer find the document I originally found on your website, but I noted that the copyright date was October 1996.<\/p>\n

Your Doc1 is a copy of the original paperback book and has the correct Capacitive Transformer circuit schematic,\u00a0\u00a0description and figure numbers. \u00a0So you already have the \u2018corrected\u2019 version. \u00a0The paperback is correct<\/strong>.<\/p>\n

The only change I see is that I no longer recommend using electrolytic capacitors for the secondary\u00a0(lower voltage) capacitor. \u00a0Electrolytics are NOT rated for continous duty AC and will fail in a fairly\u00a0short\u00a0time.\u00a0\u00a0I didn\u2019t know that when I originally tesed them<\/em>.<\/p>\n

Your Doc2 is the download of our conversion of Doc1 to an electronic version. \u00a0It is supposed to be\u00a0IDENTICAL to your Doc1. \u00a0In the process of conversion there were several errors that have caused your\u00a0appropriate\u00a0confusion.<\/p>\n

1. The drawing that was supposed to be figure 1 (the simplest Capacitive Battery Charger) was\u00a0accidentally deleted altogether (but is still in the CBC book).<\/p>\n

2. The drawing that was supposed to be figure 2 (example of Capacitive Transformer) is currently in the\u00a0place of figure 1 (so where it says \u2018fig. 2\u2019 in the document, refer to fig. 1).<\/p>\n

3. The drawing that is currently labelled figure 2 is the \u2018Capacitive Battery Charger, with options\u2019; which wasn\u2019t\u00a0supposed to be in the Capacitive Transformer document. \u00a0However, it doesn\u2019t matter because neither it\u00a0or the simple CBC drawing (original fig. 1) were CT circuits anyway. \u00a0The ONLY CT circuit is labelled\u00a0correctly (as the Capacitive Transformer), even if it\u2019s figure number and placement are currently wrong.<\/p>\n

I will put a note up in the Capacitive Power Supply Resources about these errors.
\nIn the meantime you can now proceed with your project.
\nI thank you for bringing this matter to my attention.The error I believe is on attachment Doc2-4. The figure 2 is obviously the \u201cCapacitive Battery Charger, with options,\u201d and it should be the picture of the \u201cCapacitive Transformer.\u201d<\/p>\n

You are correct.and also any insight where I can buy the parts to build a charger for a 115 VDC battery pack.<\/p>\n

I get my capacitors from surpluscenter.comI appreciate the work you\u2019re doing. It\u2019s encouraging. I\u2019d love to be on your subscription list.<\/p>\n

You\u2019d need to subscribe yourself; it\u2019s part of double opt in requirements by my ISP.\u00a0Subscribe to the\u00a0Eagle-Research\u00a0newsletter at the bottom of our home page (if you haven\u2019t already) to be informed when new information\u00a0is available.<\/p>\n

\nPersonal Tweets ( ecopegasus )I also want to note that if you are charging a vehicle battery while it is in the vehicle, it is a good idea to at least disconnect the \u2018positive\u2019 battery terminal; so that the charging voltage from the CBC will not go into the vehicle\u2019s electrical\/electronic system. \u00a0Safest is to disconnect both battery terminals.\u00a0I had two experiences with my RV that show the importance of this cautionary measure.\u00a01. My RV had been parked for some time and the chassis (engine) battery had drained (I now disconnect the chassis battery when I park the RV). \u00a0When I went to charge it there must have been some sulfation because the initial battery voltage rose to 22 VDC. \u00a0I heard a pop inside the RV and discovered that my\u00a0inverter\u00a0had fried (it couldn\u2019t take that high a voltage). \u00a0Cost to replace $200. \u00a0I\u2019ve also subsequently upgraded my \u2018charging relay\u2019 circuit so that the coach batteries (and inverter) are not connected to the chassis battery unless the engine is running.\u00a02. My CBC had developed an internal short, but it was still working at half power so I hadn\u2019t bothered to fix it. \u00a0There was no problem charging \u2018normal\u2019 vehicle\u2019s batteries or even the RV battery EXCEPT that this particular time I had the RV coach plugged into the Grid (so the RV would have electrical without using its storage batteries and inverter). \u00a0The electricity (from the Grid) that was feeding the CBC was on an opposite \u2018leg\u2019 of the 240 VAC, so (because of the CBC internal short circuit) I had a 240 VAC direct short back through the RV\u2019s 12 VDC electrical system to the Grid. \u00a0This fried a bunch of things in my chassis electrical\/electronic systems (primary fuse box, gauge cluster, ABS, headlights, etc.). \u00a0Estimated cost to repair by Ford was 2 weeks time and parts, in the range of $8000. \u00a0Since I\u2019m a mechanic and know how to buy parts off eBay I repaired it for $600 in two working days. \u00a0\u00a0So\u2026 I recommend disconnecting the positive lead of your battery. \u00a0Generally I still don\u2019t if I know the battery is good (no sulfation) and I know my CBC is good (no shorts). \u00a0But I\u2019m telling you this story now so you can be aware of the potential issues.<\/p>","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false},"product-resource-group":[112],"restricted-resource-tag":[],"class_list":["post-1048","product-resource","type-product-resource","status-publish","hentry","product-resource-group-capacitive-power-supply-resources"],"acf":[],"_links":{"self":[{"href":"https:\/\/aquacure-jeffro-dev.linksdev.com\/es\/wp-json\/wp\/v2\/product-resource\/1048","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aquacure-jeffro-dev.linksdev.com\/es\/wp-json\/wp\/v2\/product-resource"}],"about":[{"href":"https:\/\/aquacure-jeffro-dev.linksdev.com\/es\/wp-json\/wp\/v2\/types\/product-resource"}],"wp:attachment":[{"href":"https:\/\/aquacure-jeffro-dev.linksdev.com\/es\/wp-json\/wp\/v2\/media?parent=1048"}],"wp:term":[{"taxonomy":"product-resource-group","embeddable":true,"href":"https:\/\/aquacure-jeffro-dev.linksdev.com\/es\/wp-json\/wp\/v2\/product-resource-group?post=1048"},{"taxonomy":"restricted-resource-tag","embeddable":true,"href":"https:\/\/aquacure-jeffro-dev.linksdev.com\/es\/wp-json\/wp\/v2\/restricted-resource-tag?post=1048"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
