A portable backup starting device for a vehicle includes an internal power source, a switching circuit, a first voltage detecting circuit, a first electrode clip, and a second electrode clip. The first electrode clip and the second electrode clip are configured to connect to a first end and a second end of a vehicle load; the internal power source has a first electrode and a second electrode. The first electrode is coupled to the first electrode clip, and the second electrode is coupled to the switching circuit; and the switching circuit is coupled to the second electrode clip. The first voltage detecting circuit is coupled to the switching circuit, the first electrode, and the second electrode.

This disclosure relates generally to methods and systems for determining the power load disaggregation profile of a building. Most of the conventional techniques are algorithmic centric, specific to certain scenarios and does not employ the low-sampling rate data due to the complexity involved. Present disclosure determines the power load disaggregation profile of the building using the low-sampling rate power consumption data accurately. According to the present disclosure, firstly, the background power loads are detected and removed from the low-sampled data samples. Next, a robust event detection mechanism is employed to detect the events when the change in the power consumption occurred, and such events are paired using the iterative pairing technique. Further, a set of event clusters are formed using the density-based clustering technique and lastly, each of the set of event clusters are classified with each appliance type using a rule-based classification technique.

A method for testing an electrical device installed in an energy system includes: receiving an identifier and a test identification (testID) associated with the electrical device; validating the identifier and the testID; in response to determining that the electrical device is registered and communicating: setting and storing a polling rate and a posting rate of the electrical device, setting a first plurality of pre-conditions associated with a first test, and in response to determining that the first plurality of pre-conditions is met, performing the first test by: executing a first set of test commands associated with the first test, receiving responses to the first set of test commands of the electrical device, determining first test results based on the responses to the first set of test commands, storing the first test results, and determining whether the electrical device has passed the first test.
