4 FAQs about Multiple strings and single parallel batteries BMS

What is the difference between a battery array and a BMS?

Note that a single BMS handles multiple strings connected permanently in parallel. A battery array is different from a single battery with multiple strings in parallel. In that case, each string is a single battery with its own BMS and its own protector switch. Extremely few BMS are compatible with battery arrays.

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.

Can a BMS handle multiple strings?

There are: those few BMSs that can handle multiple strings use standard Li-ion BMS ICs. Each IC handles a bank of cells (e.g., 12 cells for the LT68xx ICs). Each bank is isolated from the other banks and from the low voltage power supply and communication lines. The banks are wired to the cells.

How do Battery strings work in a parallel set?

Note: Energy from the battery is always sourced from the system of the lowest impedance. This is why the strongest battery string provides the power first and when it becomes depleted less than another string, that one then takes over. In a parallel set, they work in unison to balance each other out.
