XING BMS 2.0 PARTS

BCU (Battery Control Unit)
XING Mobility designed Battery Management System (BMS) provide the battery performance prediction with battery pack current and voltage measuring. Using Extended Kalman filter (EKF) to execute cross-validation to achieve high accurate State of Charge (SOC).
CMU (Cell Monitoring Unit)
With real-time monitoring of cell voltage and temperature on multiple measuring points, Cell Monitoring Unit (CMU) performs passive cell balancing to increase battery system reliability and achieve optimized performance.

Dynamic State of Power (SOP) algorithm advises the optimal power in/out put in various battery status. This algorithm is to monitor and improve State of Health (SOH) status in different applications.

XING BMS 2.0 architecture is designed as the master and slave pack configuration to achieve scalable capacity up to 16 strings.

OTA
XING Mobility designed Over-the-Air (OTA) unit provide real-time global mobile network data transmission. For malfunction tracking of application operation, to enable identification and resolution of warranty issue before occurred. Standard designed port and reliable cloud platform of GCP & AWS for BMS upgrade to reach the latest firmware version or customized new-adding feature.

XING BMS 2.0 SAFTY

XING BMS 2.0 functionality not only covers real-time cell monitoring but support real-time HV insulation detection and High Voltage Interlock Loop (HVIL) design to ensure entire battery pack safety while charging and discharging.

XING developed Active Safety Module (ASM) combines current sensors, isolation detection, fuses and contactors to handle faulty conditions like short-circuit, over current, overcharge, over-discharge, and loss of isolation.
