select the highest CVL in Multible Batterie Systems #56

Setup: DVCC? yes

I have three banks 24V/300Ah with JK-BMSes in parallel. because i want to reduce the Voltage as much as possible, the Batteryaggregator should read the highest CVL of the Batteries so that all Batteries can finisch absobtion or balancing or Load_to_SOC_reset. Now Batteryaggregator takes the lowest CVL of the Batteries. It is possible to add a switch for that?

My english is bad. Therfore i asked a friend for better text: I am currently using a setup with three 24V/300Ah battery banks equipped with JK-BMSes, all connected in parallel. My primary goal is to ensure that all batteries can complete absorption, balancing, or reach the Load_to_SOC_reset state effectively. Currently, the Batteryaggregator selects the lowest CVL (Charge Voltage Limit) from the batteries, which might not be optimal for my system.

Could it be possible to introduce a switch or setting in the Batteryaggregator that allows for the selection of the highest CVL instead? This change would help in making sure all batteries are adequately managed during their charge cycles.

It should use the highest CVL when balancing (and the lowest otherwise). Do they not reach the balancing stage?

Thanks for your reaction. In my case it would better if always th highest CVL is in use

I've added a max_always CVL mode:

"cvlMode": "max_always"
