To meet the diverse architectural requirements of BMS systems, Lika Power Control offers single‑channel, dual‑channel, and enhanced‑isolation daisy‑chain communication isolation solutions. For mainstream energy storage applications, we recommend the LKBMT10; for 1500 V high‑voltage systems, the LKBMT10H01 is ideal; and for multi‑AFE cascading and high‑density PCB designs, the LKBMT20 is the preferred choice, helping customers swiftly select the right product.

To meet diverse system voltage levels, AFE counts, and PCB space constraints, Lekai Power Control offers single-channel, dual-channel, and enhanced-isolation product solutions.

While ensuring system reliability, achieve an optimal balance between cost and performance.

Single-channel solution (LKBMT10 series)

The device integrates a set of independent communication isolation channels, consisting of an isolation transformer and a common-mode choke (CMC).

Dual-channel solution (LKBMT20 series)

The device integrates two independent communication isolation channels internally, enabling simultaneous support for both TX and RX link transmission.

Note:

Single-channel and dual-channel refer to the number of communication links, while the presence or absence of an integrated common-mode choke (CMC) indicates the device’s EMI suppression capability; these two factors pertain to distinct design dimensions.

The LKBMT10 is suited for cost‑sensitive and standard energy‑storage BMS applications, balancing compact form factor with reliable communication. The LKBMT20 features a dual‑channel integrated design that supports dual‑link communication simultaneously, delivering superior performance in PCB space utilization, EMI characteristics, and system stability, making it ideal for multi‑AFE cascading and high‑density energy‑storage system designs.
