Title: Balancer Schematic for Lipo Charger. Post by: abhi.vishw on March 07, 2015, 03:07:35 PM Hi,
I have build a Lipo Charger based on MAX1758 IC. The results are quite impressive. 8 Pin Dip switch is used to select No. of Cell's, maximum charging current is 1.5A and other decent features. However, i would like to add a balancer to the circuit so the cells are balanced while being charged. A good balancer schematic is one like this (http://www.rcgroups.com/forums/attachment.php?attachmentid=4678373), but only problem is how to make the charger/balancer automatically select the no. of cells to be balanced? I was looking around for the schematics of Turnigy E3 Charger as it is quite similar to this charger. If anyone could help with this. I already have a Turnigy Accucel 6, so this is just for experimentation purpose. Title: Re: Balancer Schematic for Lipo Charger. Post by: Power_user_EX on June 27, 2017, 12:58:12 PM Are you using any microcontroller ? If yes then, maybe sense the inputs coming from balance leads to check if any voltage is present on the leads. You might need an Analog multiplexer/Switch.
A block diagram or basic schematic of your design can help a lot. I am confused as to whether you want to control pin 11(CELL) of MAX1758 automatically or just the balancer circuit or both. |
