supports communication pathways for the BMS
to monitor individual cell parameters. The cell
connection system integrates sensors and provides
reliable electrical and communication links, allowing
the BMS to receive real-time data on voltage,
current, and temperature from each cell. If an error
or anomaly is detected, the BMS can control the cell
connection system to isolate the fault and prevent
further damage.
Amphenol helps designers create safe e-mobility
solutions by
• Developing advanced high-voltage connectors
that ensure reliable and safe power transmission
within EVs
• Integrating real-time temperature monitoring
sensors into connectors to prevent overheating
and potential electrical faults
• Providing robust battery disconnect units
that enable safe and efficient disconnection of
high-voltage batteries during maintenance or
emergencies
• Offering high-accuracy tunneling
magnetoresistance (TMR) current sensors that
monitor and manage high-power flows
BMS have evolved towards integrating more
accurate sensors and better synchronizing
key measurements in different EV battery
architectures. To improve the safety of the
EV batteries, it is crucial to have accurate
measurements during charging and
discharging and a solid parametrization of
the batteries in operation."
