The KLClear BSU slave (acquisition module) series works with the various main controllers (BMU500-5/M79Cx/BMU500S/BMU06A/BMU900/BMS500) to form a master-slave BMS; it covers cell-count configurations such as 48/60/70/84P and supports both passive balancing (BSU series) and active balancing (S7A24/36).

Supports configurations of 36/48/56/60/70/84 series and more; two options, passive balancing (BSU series) and active balancing (S7A24/36); distributed box-type slave controller structure; combines with main controllers in one-master-multiple-slave or one-master-two-slave architectures; the BSU24/36A bus solution provides bidirectional active balancing.

• BMS slave controllers for passenger vehicles
• BMS slave controllers for commercial vehicles and heavy trucks
• BMS slave controllers for buses (bidirectional active balancing)
• BMS slave controllers for energy storage and special-purpose vehicles

For passenger vehicles we recommend the BMU500S + BSU48/60P-2 series: a system-level ASIL C solution with customized software development and functional safety.

System-level ASIL C functional safety; customized software development; BMU500S main controller + BSU48/60P-2 slave controllers.

• Passenger vehicles

Developed for light-truck battery pack management, the BMU06A+BSU60P master-slave combination adopts a distributed master-slave architecture that can be flexibly deployed following the per-box layout of battery enclosures, balancing system reliability with cost advantage and fitting mass-produced light-truck models.

Master-slave combination BMU06A+BSU60P; distributed master-slave architecture; fits light-truck split-box battery packs; high reliability and strong cost-performance

• Light trucks

For heavy truck applications we recommend the BMU900 + BSU36/48/60P-3 series, which has been proven in large-volume market use and delivers stable performance.
