The BMS provides intelligent component monitoring and managing of any lithium-ion battery pack, playing a key role in safety, performance, charge rate and longevity. The c-BMS24X targets applications up to 24 cells in series and 2,000 amps of continuous current, including energy storage systems (ESS), scooters, 3-wheelers, forklifts and AGVs.
Advanced software capabilities include parallel battery pack connection, battery swapping, improved fault tolerance and high accuracy of SoX measurements and prediction, advanced balancing and BMS-controlled convenience features.
By improving parallel pack capability, up to 10 battery packs are supported in parallel, enabling flexibility in battery design, automatic contactor control to avoid high inrush current as well as improved safety through redundancy and more isolated systems. Battery swap support allows for the rapid replacement of depleted batteries, based on powerful software algorithms.
Quickly swapping batteries eliminate charging time while supporting battery swap station infrastructure, said Sensata. The result is increased vehicle uptime, critical for light electric vehicles and lift trucks.
Senata’s proprietary SoX algorithms increase battery health and performance via the measurement and prediction of battery state of charge (SOC), state of health (SOH), state of power (SOP) and state of energy (SOE) of the battery with high accuracy and improved fault tolerance and robustness. The system provides an advanced approach to difficult-to-handle applications and cell chemistries such as lithium iron phosphate and hybrid applications, where determining balancing need is difficult. Controlled convenience features include battery heater management and automatic sleep mode for low power consumption in idle state, improving usability of the BMS.
The c-BMS24X will be showcased at The Battery Show Europe in Stuttgart, Germany, May 23-25 at Sensata’s stand 10-C10.
