Lithium 58.4V 11A Chargers @ EV Battery Center
Hello to all who are building lithium packs. I got an email from Neli @ EV Battery Center letting me know that in cleaning up the storage area at their warehouse, she has found 6 brand new C1000 chargers with mounting brackets and 14GA charge cable that were part of the last order of 2017 and got shuffled aside when Nick got sick. They are available on their web site.

Does this work well with the Zeva BMS? Via CAN connection or relay? And I assume this more of an overnight charger?

I don't think that charger has any kind of interface. At least mine which is similar doesn't. It's a pretty basic charger and for me, 10A is not enough. Mine charges at 17A.

Re: Lithium 58.4V 11A Chargers @ EV Battery Center
They are programmed to shut off at 58.4V and are very accurate doing that. With the ZEVA BMS you would need to use a relay to control it for individual cell over voltage.
With the BMS supplied from EV Battery Center, before Nick passed; the BMS would stop the charger internally due to individual cell over voltage. All charging current went via a #10 black wire separately from charger thru the BMS to the pack negative. |

Re: Lithium 58.4V 11A Chargers @ EV Battery Center
I scrapped the BMS that I got from EV and built my own because I wanted to know what it was doing. Nick's BMS used a Mosfet to control the charger which I did not like so I went with a relay on my design. I adjusted the charger voltage down a bit to top out at 4.1V per cell as well. If the charger is working properly and my cells are balanced, then the charger shuts off before the BMS terminates the charge. My charger displays voltage and current (switched to one or the other) while charging.
I have two chargers that came with my Yamaha cart that I plan to try to modify for lithium charging. I need to figure out how to adjust the voltage and to override the interlock that it has that communicated with the old Yamaha controller. |
