La description
The high-voltage wiring harness inside the car connects the power
battery and the high-voltage junction box, the high-voltage
junction box and the motor controller, the charging port and the
car charger, etc. Now let's talk about its design ideas.
The first is wire diameter design: what needs to be considered are
the load circuit, rated current, wire and ambient temperature, the
reduction factor of the allowable current of the bundled wire
harness, and so on. Verification formula: allowable current value
of wire × reduction of energization rate caused by ambient
temperature × reduction coefficient caused by bundling > rated
current value.
Followed by high-voltage wiring harness design requirements:
1. The design of the high-voltage wiring harness should meet the
assembly requirements and component layout requirements of the
whole vehicle
2. Provide power and grounding for high-voltage components, and
combine with switches and relays to realize functional control of
high-voltage equipment
3. Meet the requirements of high voltage and high current use,
conventional vehicles meet **0V, commercial vehicles meet ***0V,
according to the requirements of high-voltage system components,
the current needs to reach ******0A
4. Meet the temperature requirements of **5 degrees and **0 degrees
in special cases, and the service life of the high-voltage wiring
harness is higher than the ****-hour requirement of ordinary
cables
5. Shielding effect: EMI (Electromagnetic Interference) and RFI (RF
Interference) vehicle system problems need to be solved by using
appropriate shielding methods.
6. Flexibility and bending resistance, the interior wiring space of
the car is small, and the high-voltage wiring harness should be
soft enough to hover in a small space.
