Description
The PCS converts the battery DC voltage
discharged from the ESS into specified
AC voltage and converts AC voltage into
DC voltage to charge the ESS. It
supports 100% unbalanced loads.
The lead-acid battery box is optional. It
works with the thermal runaway
suppression system to supply power to
the TRSD.
The SmartLogger can be installed inside
the ESS in the single ESS scenario. The
SmartLogger manages the voltage,
current, temperature, and energy of
each ESS in an array.
When a thermal runaway alarm is
generated for any PACK, the TRSD host
communicates with the BMS to respond
to the fire alarm and start automatic
fire suppression control.
Detects water based on the resistance
change between both electrodes.
The RCM consists of the BCU, rack
power control board, fuse, contactor,
and disconnector. It is used for ESS
control, short-circuit fault detection,
insulation detection, leakage current
detection, high-precision current
sampling, auxiliary power supply, and
connecting to the ESS on the mobile
app.
Stores documents related to the ESS,
such as the quick guide.
