FAQ: SBM in the disconnect state – what to do?

Question: After discharging a battery pack there is no voltage on the output of the SBM. The battery pack is OK, but the SBM does not give any voltage on the output pins (P+ and P-). What is wrong?

The protective function of the SBM will di

Testing a LTO technology BMS

Testing a LTO technology BMS

In addition to testing the LTO cells, we are also verifying the functional operation of the LTO (lithium titanate oxide) BMS to allow the management and the proper function of the pack.

We are working on a 24V pack consisting of 10 LTO cells.

Keep waiting for the details coming.
