The invention involves the automated testing of HVAC units using an energy management system. The automated HVAC test is performed to understand if one or more HVAC units are operational across one or more locations. If an HVAC unit is not operational, HVAC testing could be performed to understand which component or stage of the HVAC unit is not working as designed. The automated HVAC test is also used to calculate the efficiency of the HVAC unit(s) being tested. The various HVAC tests are performed on all HVAC units as a form of preventative maintenance and diagnostics. These tests can be scheduled on-demand, for a future date and time, or on a recurring schedule (monthly or quarterly). A report is generated for each HVAC test and can be viewed and exported from a cloud-based energy management platform.

The present disclosure relates to a battery diagnosis system including a processor configured to: receive high-voltage battery information of a parked car; measure impedance of a battery through the received battery information; and determine, based on a comparison between a normal battery impedance and an abnormal battery impedance, that a battery having an abnormal battery impedance is an abnormal battery.

A first process acquires drive system data indicating a dynamic state of a drive system. A second process performs frequency analysis on the drive system data so as to acquire analysis data indicating a power spectrum of the drive system data. A third process derives the Gaussian distribution of the analysis data and acquires a feature amount indicating the Gaussian distribution. A fourth process determines whether the drive system is operating abnormally based on the feature amount.
