technology
5.1 Overview of high-voltage components
General description
The most important components of the A6 high-voltage system
are the electric drive motor - V141- , the hybrid battery unit - AX1- ,
the high-voltage wiring and the power and control electronics for
electric drive - JX1- . The power and control electronics for electric
drive contain the electric drive control unit - J841- , the voltage
converter - A19- and the DC/AC converter for drive motor - A37- .
Further components include the electrical air conditioner com‐
pressor - V470- , the low-temperature cooling system, the cooling
module for the hybrid battery unit - AX1- and the disengagement
clutch in the electric drive motor - V141- .
