Illustration 13: Connectors of the Energy Storage ES 5-2.4
Main terminals are used for charge and discharge. Terminals are threaded, with M8 for the
"+" (positive) connection and M6 for the "-" (negative) connection.
Terminal screw connection is only approved for the following combination, which shall be
used in vehicles:
Screw:
– B- Terminal: Stainless steel screws - M6x12 DIN 14580
– B+ Terminal: Stainless steel screws - M8x12 DIN 14580
Washer:

4.3 Power Unit PU 5-10

The BOSCH MOTORSPORT e-GoKart System is propelled by the e-GoKart Power Unit PU
5-10.
The Power Unit PU 5-10 consists of a 5-phase air-cooled electrical claw-pole machine
(electrically exited synchronous electric machine) and an air-cooled power electronic (DC/
AC inverter) with an integrated microcontroller logic controller. The Power Unit PU 5-10
can provide torque in forward and backward rotational direction. Since the Power Unit PU
5-10 is air-cooled it has a preferred rotational direction. For series clockwise direction is
available; counterclockwise is available as sample. Positive torque is denoted as boost
mode. A negative torque is denoted as recuperation mode. The Power Unit PU 5-10 is
scalable, that means the BOSCH MOTORSPORT e-GoKart System can be equipped with up
to two Power Units PU 5-10.
