What is Automotive HPC and Why Are High Temperatures Considered a Series Issue?

Automotive HPCs (CPU) are a core component for electric vehicles and they have many characteristics like high-frequency/high-performance, high-speed transmission interfaces, complex processing, resource allocation, and more. With the complex user scenarios of various vehicles, the automotive HPC will put the processing, signal transmission, system stability, durability, compatibility, and security levels of the entire platform to the test.


In various situations of everyday life, high temperatures can pose a threat to these platforms. Situations such as parking outdoors in the sun for long periods, charging the electric vehicle’s battery, or abnormally high temperatures emitted by the cooling system, can cause high temperatures for the automotive HPC. Once a vehicle encounters this, it could affect the operation of components like automotive HPCs or ECUs, leading to unpredictable issues and malfunctions.


Overheating CPUs: The Real Reason Why Tesla Recalled 1.3 Million Vehicles

According to the National Highway Traffic Safety Administration (NHTSA), Tesla had a recall of 1.3 million vehicles due to CPU overheating issues.

The Truth Behind Vehicle Recalls: Why Are High Temperatures a Serious Issue for Electric Automotive Components


Potential Issue

During fast charging or preparation, the CPU may slow down or restart due to high temperatures. As a result, the main touch control screen of the car will stop working and stop displaying the rearview camera image, gear selection, windshield control settings, and warning lights, increasing the risk of accidents.


Case Analysis

The cause of this issue is likely due to high-temperature-related user scenarios not being considered during product development. Since more car manufacturers and Tier 1 developers lack experience with PC components, software, hardware, and related fields, they are usually unfamiliar with high-performance platforms like automotive HPCS. This leads to manufacturers not being able to design and simulate various
types of user scenarios for testing.
