(click on image to enlarge)Here is a diagram of a possible 12volt, 36 volt circuit for a 36 volt electric bicycle using three twelve volt batteries in series. a second 12 volt circuit may be able to be made by wiring a second circuity by wiring up the batteries in parallel as shown in the diagram.
Some have argued that this configuration may cause a short in one or both of the circuits. And if a short would exist, it may be fixed through the use of diodes.
Do any of you have any comment on whether this configuration is feasable without and/or with diodes(not shorting)?
Argh!
ReplyDeleteDon't try it! You're effectively shorting each battery (remove the 2 leads from the batteries to the 36V load and you will see what I mean).
Diodes would "rectify" the problem (excuse the pun), but obviously would have to be appropriately rated to carry the current (you will also suffer a 0.6V drop over each diode).

PS: Great Blog!!
Thanks for the insight JB.
ReplyDeleteWhere in the system would the diods be places? How many, and in which direction?
Thanks.
I really appreciate the blog since the first time do I saw it. Now they have reached another milestone which lead us to report about it, and I think it's a great new... as the content of the text.
ReplyDeleteExcellent blog! I truly love how it’s easy on my eyes as well as the info are well written. Great job!!
