Sensata Technologies i-BMS

Sensata Applied sciences unveiled its i-BMS battery administration system (BMS) for electrified functions as much as 60V. Sensata stated the cell chemistry agnostic, compact, built-in BMS is designed for automated guided autos (AGVs) and robotics, amongst different merchandise.

Sizzling swap performance and parallel battery pack assist permit for the flexibility to rapidly alternate depleted batteries with absolutely charged batteries. For instance, when a robotic returns to its base to choose up a brand new load, its depleted batteries could be swapped for charged ones.

Whereas measuring solely 65 x 200 mm (2.6 x 7.9 in), the i-BMS PCB board is supplied with all the things required to handle and preserve a battery system with out the necessity for any exterior elements. All important elements are pre-integrated into the system, together with a pre-charge circuit, on-board present measurement, MOSFET energy switches for battery disconnect, and a DC/DC energy provide. The answer options key elements which might be ASIL C Security rated and embrace self-test capabilities for security important measurement circuits.

The algorithms in Sensata’s BMS software program guarantee correct state-of-power (SOP) predictions based mostly on cell inner resistance, voltage and present constraints, exact state-of-charge (SOC) calculations, and (state-of-health) SOH calculated based mostly on growing old impact.

The BMS Creator configuration software program permits the battery pack designer to create a singular battery setup by defining application-specific BMS parameters and security methods, optimizing battery operation.

Different software program options embrace measurement of charge of change of temperature to foretell thermal runaway, dynamical regulation of present in excessive thermal situations, in addition to superior parameter settings for CAN communication.
