In hybrid vehicles, how to adjust the relationship between battery, motor and internal combustion

engine has been a concern. According to foreign media reports, in a recently published patent

application, Porsche proposed a way to solve the battery cooling problem using turbochargers.

The patent application is called "VEHICLE HAVING A HYBRID DRIVE." Firstly, the external air

is compressed by a traditional turbocharger or electric supercharger. Then, make the air flow

through the booster, such as "blower, pump, compressor, etc." If the system uses a conventional

turbocharger, these auxiliary devices can be used to provide cooling air to the battery when the

engine is running at low speeds. In other words, if the battery is still hot and the turbocharger is

not providing enough cooling airflow, more airflow will be generated through the booster. If the

system uses an electric compressor instead of a conventional turbocharger, such equipment

may not be required.

The pressurized air then passes through the intercooler and through the heating element. In

cold weather, this will be used to heat the intake air to adjust the condition of the battery. After

completing this process, the airflow passes through the battery's bypass valve. Basically, Porsche

thinks that if the battery doesn't need to be cooled, it's okay to bypass the bypass valve and go

straight into the engine. The valve is also somewhat like a thermostat, which can be opened/

closed to maintain the desired battery temperature.
