1.
Traction Battery:
Four Li-ion battery packs supply a
maximum of 738V at 110A. Battery electrodes are made of
Carbon, Lithium, Nickel, Manganese and Cobalt.
2. Charging switch unit (CSU):
The primary function of the
Charging Switch Unit (CSU) is to act as a circuit breaker for
the charging plug.

3. DC/DC converter:
The DC/DC converter converts the
traction voltage of 600 V DC to 24 V DC. In electric trucks, the
DC/DC converter charges the 12 V batteries and handles the
loads connected to the 24 V system.
4. Traction Voltage Junction Box (TVJB):
The TVJB has 2
variant combinations depending on the number of
high-current and low-current connection interfaces.
The TVJB distributes power in the electric propulsion system.
5. Electric Motor Drive (EMD):
The EMD converts 600V DC
to three-phase AC. The EMD runs the electric motor and
controls the speed, torque and calibration.
8. Electric Motor:
2 three-phase AC motors with 400kW to
334 kW capacity power the truck.
9. Electric motor, hydr. ePTO:
Three-phase Ac motor with
70kW power the hydraulic pump.
10. Electric Motor Drive (EMD)- hydr. ePTO:
The
EMD- ePTO converts 600V DC to three-phase AC. The EMD
runs the electric motor and controls the speed, torque and
calibration.
6. Charging inlet, CCS 1 type :
The CCS inlet is used for
600V DC charging. The CCS inlet is equipped with an
actuator that prevents accidental disconnection of the
charging plug on truck side.
7. Traction Voltage Monitoring Unit (TVMU):
The TVMU
performs measurements in the traction voltage system,
detects any potential hazardous situation and communicates
this to the HPCU (Hybrid Powertrain Control Unit).
