Sensata Technologies debuted new Battery Management Systems at the Battery Show North America in Novi, Michigan from September 14 to 16. In addition, Sensata highlighted its sensing and control solutions that help make energy systems safer, cleaner, more efficient and connected at the show.
The brain behind the battery for a diverse range of electric vehicles, the BMS is the intelligent component that monitors and manages lithium-ion battery packs. The new i-BMS Battery Management System from Lithium Balance, acquired by Sensata earlier in the year, is a cell chemistry agnostic, compact, integrated BMS developed for the cost-optimized mass-production of applications up to 60V, such as 2-, and 3-wheelers, automated guided vehicles (AGVs), and robotics.
The i-BMS is a long-term solution for customers who require the highest levels of safety, performance and measurement accuracy. The solution features key components that are ASIL C Safety rated and self-test capability for safety critical measurement circuits.
While measuring only 65 x 200 mm, the i-BMS is equipped with everything required to manage and maintain a battery system without the need for any external components. This includes a built-in pre-charge circuit, on-board current measurement, MOSFET power switches for battery disconnect, and a DC/DC power supply.
The i-BMS’ software design features parallel pack and hot swap capability, while advanced SoX algorithms ensure high precision. Using the BMS Creator™ configuration software, the i-BMS allows the battery designer to create a unique battery by defining application-specific BMS parameters and safety strategies, optimizing battery performance and life.
i-BMS main features:
– Integrated system
– Up to 15 voltage channels
– 6 temperature channels
– 25 – 60 V
– 1 CAN channel
– CREATOR config. software
– Parallel pack & Hot Swap functionality
– On-board pre-charge circuit, auto-calibrated shunt, battery disconnect, DC/DC power supply
– Suitable for scooters, motorbikes, 3-wheelers, AGVs, robotics and low current material handling applications
