AC charger
Powertrain control unit
DC/DC converter control unit
DC charge-connection unit (DC box)
Which statement(s) about model series 243 is/are correct?
The installation location of the AC charger on the 7-seater is in the underbody in front of
the high-voltage battery.
The vehicle socket is located at the right rear of the vehicle.
The installation location of the DC charge-connection unit is on the left side of the trunk.
The installation location of the DC charge-connection unit is in the center of the engine
compartment.
The installation location of the AC charger on the 5-seater is in the underbody in front of
the high-voltage battery.
Which statement(s) about pre-entry climate control is/are correct?
Pre-entry climate control is possible only if the high-voltage battery is sufficiently charged.
When the vehicle is parked, pre-entry climate control via the vehicle key can be activated
only on the driver's side.
Pre-entry climate control at departure time is activated and set in the multimedia system.
Pre-entry climate control is not provided for the EQA.
Pre-entry climate control via the vehicle key must be activated in the multimedia display.
Which statement(s) about the 7-seater (X243) is/are correct?
The high-voltage PTC heater is installed in the vehicle interior.
The control unit for the high-voltage disconnect device is installed in vehicles with a third
seat row. It is located directly on the high-voltage battery.
The DC/DC converter control unit is installed in the trunk of the vehicle.
The DC charge-connection unit is installed in the underbody of the vehicle.
The AC charger control unit is located in the underbody of the vehicle.
Which statement(s) about the components of the EQS is/are correct?
As with the other model series, the interlock signal is monitored in the BMS control unit.
The charging plug detection function of the on-board charger prevents driving off with the
charging cable plugged in.
The vehicle interior is heated by the high-voltage PTC heater integrated in the air
conditioner housing.
The DC/DC converter supplies the 12 V on-board electrical system with voltage.
The DC/DC converter control unit forms the interface between low-voltage and high voltage
on-board electrical system.
Which statement(s) about the components of the high-voltage interlock circuit is/are correct?
The DC charge-connection unit is part of the interlock circuit.
The DC/DC converter control unit is part of the interlock circuit.
The electric refrigerant compressor is part of the interlock circuit.
The C-AAC control and operating unit is part of the Interlock circuit.
The AC charger is part of the interlock circuit.
Which statement(s) about the high-voltage battery in the EQS (V297 model series) is/
are correct?
The lithium-ion battery contains the cells, the battery management system and the highvoltage
contactors.
Two different battery sizes of the high-voltage battery are available for the EQS.
The instrument cluster indicates whether the high-voltage battery is safe for transport.
The high-voltage battery is located in the vehicle floor.
The high-voltage battery is located in the trunk.
Which statement(s) about the high-voltage interlock circuit of the EQS is/are correct?
Due to the new architecture, an interlock function is no longer necessary.
All high-voltage components report the interlock status to the central powertrain control
unit via a communication bus.
The advantage of the decentralized interlock system is that each component is monitored
independently, which simplifies diagnosis in the event of damage.
The EQS is the first model in the EVA 2 architecture to use a new decentralized interlock
system.
a) The EQS again uses the familiar central interlock system.
Which statement(s) about the interlock is/are correct?
Located in each high-voltage plug connection or cover is a contact bridge, which
disconnects the interlock when it is disassembled.
The control unit for the high-voltage disconnect device is installed in vehicles with a third
seat row.
The monitoring of the interlock takes place in the power electronics.
The control unit checks the interlock with approx. 400 V.
Operating the high-voltage disconnect device interrupts the interlock and terminal 30C.
Which statement(s) about the on-board electrical system (low-voltage and high-voltage) of the
EQS is/are correct?
All control units used in the EQS are supplied via the 12 V on-board electrical system battery.
The 12 V on-board electrical system is supplied with energy from the high-voltage on-board
electrical system with the aid of the DC/DC converter.
The EQS is the first vehicle to use a 48 V on-board electrical system in addition to the highvoltage
on-board electrical system.
A 12 V lithium-ion battery is used in the EQS.
The power supply in the EQS is provided via the high-voltage on-board electrical system
with high-voltage battery and via the 12 V on-board electrical system with 12 V on-board
electrical system battery.
Which statement(s) about thermal management in EQS is/are correct?
Coupled with the NT1 cooling circuit is the passenger compartment heating circuit with
integrated 8 kW high-voltage PTC heater.
The NT2 cooling circuit contains the high-voltage battery and a high-voltage PTC heater
(5.2 kW).
The NT1 cooling circuit contains the DC/DC converter, the electric machines with power
electronics and the chargers.
The thermal management system consists of two low-temperature cooling circuits.
The thermal management system consists of a low-temperature and a high-temperature
cooling circuit.
