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 60 V, such as two and three-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 65×200 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:
Up to 15 voltage channels
Six temperature channels
25 – 60 V
One CAN channel
CREATOR config. software
Parallel pack & Hot Swap functionality
On-board pre-charge circuit, auto-calibrated shunt, battery disconnect, dc/dc power supply
