the battery compartment and battery cabinet use TECs. The HXC150S consists of an internal
circulation fan, an external circulation fan, and a heat exchanging core while the TEC consists
of a TEC and a TCUA control box. The TCUA control box controls the TEC, and the
SMU02B controls the HXC150S.

The equipment compartment is cooled by heat exchange, which is implemented through
internal circulation and external circulation.
