AI Technical Summary
Technical Problem
In the prior art, low-voltage DC converters fail to perform appropriate variable control based on the status of the air conditioning system blower during operation, resulting in reduced fuel economy.
Method used
The low-voltage DC-DC converter controller dynamically adjusts the output voltage according to the blower's operating status and output settings, including providing a constant voltage when the output is high and optimizing the voltage supply by taking into account the auxiliary battery's power status when the output is low.
Benefits of technology
It improves vehicle fuel economy and prevents unnecessary electricity consumption and energy waste.
