General Information
High Voltage Battery Terminal
The figures below show an example of an MCU cable
gland where the High Voltage battery (Traction
Battery) is connected.
High-voltage Battery Pre-Charge Circuit
The high-voltage battery must be connected to the
MCU using specific cable assemblies. The table
below is an example for the cable specifications.
Refer to the MCU installation guide for the cable
specifications.
Important Note : It is absolutely necessary to regard
the safety precautions for the High Voltage Battery
before connecting the High Voltage Cables.
High Voltage Battery Short Circuit Protection
The MCU requires a fuse on the High Voltage DC
bus. Proper fuse rating is necessary to protect
against reverse polarity and short-circuit. Dana TM4
recommends installing a fuse with the following
characteristics:
The table below is an example.
Refer to the "Application Note - TM4 SUMO Fuse
and DC Cable Selection" published on the
"Knowledge base" section of the Dana TM4
extranet site for proper fuse selection.
The chart below is an example of the specifications
available. Other system can be used with different
wire size.
Notes** :
1. The wire size or wire wall material can be adapted
to fit required use.
2. Depending on the location of the wires, a wire
tubing (orange split loom) can be used to prevent
abrasion or other effects that could damage the
wires.
3. Based on a temperature of 85 °C.
4. The color orange is recommended for safety
purposes when handling high voltage levels.
5. The external cables used for high-voltage are be
orange and shielded.
