Hi
One of my clients is looking for replacing existing HW, 2 200Wh battery >modules, which each has a BMS controller, that monitors and balances 12 >lithium ion cells (4 series connection of 3 parallel cells). Each of the >modules has SOC output in the form of LEDs.
Beyond that, the overall system has a BMS controller that is powered
from either 24VDC (grid connected) or from the batteries. This BMS
controller also has SOC, with a connected display.
The client would like a turn-key solution, so minimal NRE due to low volume.
I am looking for a supplier of finished batteries with BMS and also BMS >controller. Perhaps one of you guys has worked with this? (need a stable >supplier)
Client is based in the EU.
Thanks
Klaus

I have a list of future projects which includes a battery monitor. I
figure it might have a wire per cell (+1 at the end of the string) and
snoop voltage, ripple, and estimate cell impedance, something like
that. Measuring string current would help.

Looks good, they have a lithium battery with internal BMS at resonable
price.
No State of Charge (SoC) though for the battery. Is it possible to get
rough SoC from a lithium battery by voltage sensing only?
