BQ34Z100-G1: RELAC_JUMP_OK to 0

Part Number: BQ34Z100-G1

Hi,

We have a battery that, when charged to 100% and then left to rest, gave us a SOC jump from 99 to 65 for example.

To fix this problem, we changed RELAC_JUMP_OK to 0. After this change, we haven't seen any more SOC jump at rest
Could be have any problem by changing this parametre?

Our equipment is at rest, an average of 12hours per day, and the rest of the time it makes movements from 2A every 2minutes.

Hi,

You should not encounter problems from disabling relax_jump_ok. It will not allow RSOC jump during RELAX mode if [SMOOTH =1]

Hi,

What disadvantages could we have by disabling it?
What could we lost? SoC adjustments due to OCV...

Hello Unai,

The only disadvantage I could see is if you have a very large discharge current compared to the capacity of the battery, then SoC accuracy might be a little more inaccurate with that feature disabled. Also, pulsed loads could cause more inaccuracies.
