Bms battery matching

4 FAQs about [Bms battery matching]

What is a battery management system (BMS)?

The functionality of a BMS extends to: Ensure the BMS is compatible with your specific type of battery (e.g., Li-ion, LiFePO4, NiMH). Each chemistry has unique voltage thresholds and operational parameters that the BMS must be able to manage. Centralized BMS: Suitable for smaller packs or where cost is a concern.

How do I know if a battery is a BMS?

Start by knowing the maximum voltage limits of the BMS in each battery (not just the published high charging voltage protection limits). For example: Discover’s 12V LiFePO4 batteries have a nominal voltage rating of 12.8Vn and the BMS will protect at the maximum operating voltage of 14.6V.

Can a BMS be used in a parallel connected battery?

No matter the BMS design, because both solid-state-relays and mechanical relays have current limits, the BMS maximum current limits must be respected when designing a parallel connected bank of lithium batteries with built in BMS.

Does a BMS need to be connected to a battery?

The BMS has no internal power source, and needs to be connected to the battery for the UART communication to work. Make sure your Tx/Rx aren''t mixed up, in the picture above Tx/Rx are labeled with respect to the BMS. I could not have made this work/debugged this without a logic analyzer hooked up to the UART lines to see what''s going on.
