Our patent pending Prius Grid Charger would be perfect for charging the pack and allowing you to start and drive the car. It is the only system...
Our Patent Application has been filed! US Provisional Patent Application # 62002167. This was the last to-do before releasing our Prius Grid...
Well, I am a CPA by day, not a chemist, but there is some good info out there. Self-Discharge of NiMh cells is even worse in the low resistance...
It's harder on NiMh cells to sit unused than to be driven daily (or at least 5 days a week). Any car that sits for more than 2-3 days at a time...
You don't drive the Citrus by chance do you? My day job is in Santa Cruz and drive over the hill twice each day. I see several Insights going...
This varies by model. It must be >100% of total cell capacity in order for the re-balance process to occur. For example, the 04-09 Prius charger...
Our Patent Pending Prius Hybrid Battery Rebalancer (Grid Charger) that is going to be released this Memorial Day weekend will have a fixed 350mA...
We tried this repeatedly and did not have any success. The volt signal cable cannot handle even a small sustained load without blowing the fuse....
Yes lower current=better when grid charging cells above 100%. We are on our third & final rev of the fan motor control and almost done with the...
You are absolutely correct, and this has been done for years on the Honda cells. 350mA is an ideal power level as it allows for a 24 hour...
Wouldn't using the Prius fan itself work for this purpose? Seems like it would, but I am still learning about all the cool charge/discharge toys...
Like Eric said, the voltage levels should work, but the 'car harness' would be completely custom. Also and very critical, you would need a way to...
Thanks for the encouraging words. We hope so too! Our fan motor control board is almost done. Functions perfectly on both 1st & 2nd gen HV...
I agree that the capacity readings will be meaningless at lower discharge currents, but for recovering/improving the actual performance of the...
I just want to say thank you for posting this, and for specifically calling out Step 9c. After wasting over an hour trying to figure out what was...
How low V/cell are people discharging the Prius packs? Going deep and chancing polarity reversal has much less risk of cell damage when done at...
Getting the Prius back from the dealer today. Had her for only five days when the combination meter issue happened. Thankfully Toyota covered it...
Thanks for the kind words. The 99-03 Prius Grid Charger *is* compatible with the 04-09 Prius - but not the other way around. If you have both...
The slow controlled overcharge of the cells is what rebalances the battery pack. As the stronger cells reach full, they convert the charge energy...
Does it have HV battery cooling circuits included? If not stay far away cooling the HV battery while grid charging is critical to prevent cell...
