Talk:PriusPlus History-Battery

From My wiki
Jump to navigation Jump to search

You indicate that the batteries are required to accept up to 120A of charge from the regeneration system, yet the batteries that you have used in all your testing are only rated to accept 15A charge. Have you had any problems with this? Have you limited the regeneration due to the battery limitations that exist right now?

I am returning to this subject again as I am about to embark on my plug-in Prius Project. When using the lead acid battery pack have you had any issues with the regeneration exceeding the specifications of the batteries?

I have personally charged my string of BB20 batteries at greater than 25 amps from the grid, and though my particular PiPrius implementation doesn't yet regen into the lead acid pack, I believe Rons PriusPlus conversions do. In general SEVA:PbA batteries are more than capable of accepting any amount of charge current so long as they don't exceed the maximum gassing voltage which I believe is approximately 15 to 15.5v. Similarly you can usually draw more current than a batteries specification, until they sag below 10v or their interconnects vaporize, whichever comes first. Of course normally we don't encounter either of these extreme charge or discharge limits except perhaps in the world of BEV SEVA:Racing which tends bump up against these limitations. --Rjf 01:11, 26 January 2007 (CST)
