A37- .
For driving with the electric drive motor - V141- , the DC/AC con‐
verter for drive motor - A37- converts the 266 V direct current of
the hybrid battery unit - AX1- into 360 V alternating current. The
voltage converter - A19- converts high voltage into low voltage to
supply the 12 V electrical system. Power and control electronics
for electric drive - JX1- are water-cooled and are installed in en‐
gine compartment (front left).
The following high-voltage wires are connected to the power and
control electronics for electric drive - JX1- :
♦ High-voltage wire for hybrid battery, positive terminal - P1- to
hybrid battery unit - AX1-
♦ High-voltage wire for hybrid battery, negative terminal - P2- to
hybrid battery unit - AX1-
♦ High-voltage wire 1 for drive motor - P4- to electric drive motor
- V141- ⇒ page 43 .
♦ High-voltage wire 2 for drive motor - P5- to electric drive motor
- V141- ⇒ page 43 .
♦ High-voltage wire 3 for drive motor - P6- to electric drive motor
- V141- ⇒ page 43 .
♦ High-voltage wire for electrical air conditioner compressor -
P3- to electrical air conditioner compressor - V470-
⇒ page 49 .
Note
Fuse for electrical air conditioner compressor - JX1- is inte‐
♦
grated into power and control electronics for electric drive -
V470- .
Fuse cannot be renewed. Power and control electronics for
♦
electric drive - JX1- cannot be dismantled any further. If dam‐
aged, renew power and control electronics for electric drive -
JX1- .
