HI, ANYBODY knows about the chineese active balancing devices, are they as efficients like they claim ?

I do not understand about your solution! just connecting a supply external battery to the input bms i dont mind it was any trouble, for the can bus two wires green and white are comunication the tthird purple is to activate realay controller connecting white and green with a 330 ohm resistor you...

HI, an ingeneer and me are working, in Spain, on an active balancing system using linear technologies , ltc 3300 and companions ltc 6820 and 6804 does somebody try to use that tecnologie? , whe project to rise more than 10 amp current balancings any help will be on agreement best regards

for people who uses EV every day whe know the importance of an an efficient active balancing systems while load, the bat stops because a cells turn to low soc and you check your battery and you see you could run one hour more. I used many chineese passive balancing but they work only in...

:oops: :oops: :shock: i have perform actually mi design using isolated dc converters and i will start in contruction NB i am not engeneer i am intuitive and mi target is to built up a simple and efficient cell balnacing system, thanks for your help and understanding. i Know that big...

Whats wrong about to use caps? is better for reading dont? i slog hard evry day i use to work up mi projects , is not the first one, thanks i dont have time for learning electronics right now , i try to work out an efficient and cheap active balancing system. there are not much cheap in the market.

Whats wrong about to use caps? is better for reading dont?

FOR SHURE IS NOT NEW, LINEAR USE ic´s TO BALANCE ACTIVELY THE CELLS BUT NOT WORK FOR LIFEPO4 , ATMEL JUST BALANCE 1 AMP, AND MI PROBLEM IS I HAVE 16 CELLS , 6P 16S , I JUST LOOK FOR HELP NO NEED NEGATIVE ADVISINGS I AM NOT FOOL, BUT NOBODY KNOWS ABOUT ANALOGIC ELECTRONICS. I BELEVE IS EASY TO...

ACTUALLY I AM WORKING ON THAT SOLAR E-BIKE PROJECT POWERED BY 2 POUCH PACKS LIFEPO4 20 AMP 48 V, 320 W SOLAR PANNELS USING NASA SATELLITE CELLS AND LYEN CONTROLLER WITH REGEN FUNCTION. GOLDEN 500W MOTOR http://endless-sphere.com/forums/viewtopic.php?f=6&t=32975

I DONT KNOW ABOUT ELECTRONICS OR CIRCUITS , I JUST LOOK FOR HELP TO RESOLVE THE ISOLATIONS PROBLEMS IN MI CIRCUIT, WITHOUT USING TRANSISTORS OR MOSFETS, I WANT TO USE INDIVIDUAL DC DC CONVERTERS TO POWER UP EACH CELL FOR AN ACTIVE CELL BALANCING SYSTEM!!!!

to nubuo, paasive cell balancing use resistors to drop the extra charge from higher cells dissipate by heat with the resistors, many energy is lost on that process, flyback converters use the proper power from the batteri to power the lower cells . Nothing in power control means 100% of...

HI FRIENDS IS NOT JUST A THEORY, I AM WORKING, ACTUALLY, WITH SMALL DC CONVERTERS FROM MURATA, OR TI DC -TO DC. NOT CAPACITORS, YET, MAY BE LATER I WILL INCORPORATE ULTRACAPS TO THE POWER BANK. I NEED TO CHECK OUT BOTH, THE ONLY PROBLEM I HAVE IS TO RESOLVE THE POLARITY INCOMPABILITY, THE CELLS...

:x [attachment=1]ti 5430.JPGHi, freinds 3 years ago i started up developping a solar powered e-bike prototype. On that way i learned a lot about batteries, charging and balancing, the worst and darkest side of the process. TIred about passive chineese bms systems i decided to built up using mi...

I project to use a founding power smart 16 cells bms but mi engeneer wold like to know the rs 232 protocol to insure customised bluetooth device, somebody knows how to contact foundingpower engeneer on that forum? i rod he use answer to faq and troubles with their devices, best regards
