Systems and methods for starting-up a vehicular air-conditioning system
First Claim
1. A method for starting-up a vehicle air-conditioning system, comprising:
- at the vehicle air-conditioning system including a blower fan, a condenser fan, and a compressor, all of which are electrically coupled to a battery system;
while the condenser fan and compressor are off, starting the blower fan;
after starting the blower fan, measuring a first current drawn from the battery system, wherein the first current is indicative of current drawn by the blower fan;
and in accordance with a determination that the first current meets one or more predefined condenser fan starting criteria, which indicate that the blower fan is operating properly;
starting the condenser fan while leaving the compressor off, after starting the condenser fan, measuring a second current drawn from the battery system, wherein the difference between the second current and the first current is indicative of current drawn by the condenser fan;
and in accordance with a determination that the second current, or the difference between the second current and the first current, meets one or more predefined compressor starting criteria, which indicate that the condenser fan is operating properly, starting the compressor, wherein the one or more predefined condenser fan starting criteria differ from the one or more predefined compressor starting criteria.

Abstract
The various implementations described herein include methods, devices, and systems for starting-up a vehicle air-conditioning system. In one aspect, a method is performed at a vehicle air-conditioning system including a blower fan, a condenser fan, and a compressor electrically coupled to a battery system. The method includes: (1) starting the blower fan; (2) after starting the blower fan, measuring a first current drawn from the battery system, the first current indicative of current drawn by the blower fan; (3) in accordance with a determination that the first current meets predefined criteria, starting the condenser fan; (4) after starting the condenser fan, measuring a second current drawn from the battery system, where the difference between the second current and the first current is indicative of current drawn by the condenser fan; and (5) in accordance with a determination that the second current meets predefined second criteria, starting the compressor.

12. A vehicle air-conditioning system, comprising:
-
a blower fan; a condenser fan; a compressor; and a battery system electrically coupled to the blower fan, condenser fan, and the compressor; wherein the vehicle air-conditioning system is configured to; while the condenser fan and compressor are off, start the blower fan; after starting the blower fan, measure a first current drawn from the battery system, wherein the first current is indicative of current drawn by the blower fan; and in accordance with a determination that the first current meets one or more predefined condenser fan starting criteria, which indicate that the blower fan is operating properly; start the condenser fan while leaving the compressor off; after starting the condenser fan, measure a second current drawn from the battery system, wherein the difference between the second current and the first current is indicative of current drawn by the condenser fan; and in accordance with a determination that the second current, or the difference between the second current and the first current, meets one or more predefined compressor starting criteria, which indicate that the condenser fan is operating properly, start the compressor, wherein the one or more predefined condenser fan starting criteria differ from the one or more predefined compressor starting criteria. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
