The present invention relates to an interactive power source for electric vehicle. More particularly, the present invention provides an IoT based interactive power source for backup used in electric vehicle for improved control and monitoring.
BACKGROUND & PRIOR ART
[002]In certain circumstances, it is required to operate AC type loads from a source of DC power, such as batteries. For example, it may be highly desirable to maintain the operation of various medical devices during failures of the normal supply power distribution system. For this purpose, various rotary and static inverter systems have been heretofore proposed, including designs employing semiconductor switching components.
[003]As is known in the art, most semiconductor or solid state inverters utilize simple square wave switching. While some loads can be driven from such waveforms, others cannot. While various sine wave inverter designs have also been proposed, these typically have not been usable with a wide variety of loads, particularly loads which exhibit low power factors or which draw current unequally from the two halves of the sinusoidal waveform. Further, most sine wave inverter designs proposed heretofore are relatively expensive and complex or produce only a rough approximation of a sine wave and are thus not suitable for all loads.
[004]Among the several objects of the present invention may be noted the provision of a DC to AC inverter which provides a sine wave output waveform; the provision of such an inverter which will accommodate loads exhibiting a wide range of power factors; the provision of such inverter which will tolerate loads of drawing unequal current from the different phases of the sine wave output voltage; the provision of such an inverter which provides a sine wave output of high accuracy; the provision of such an inverter whose output voltage is highly regulated against variations in both AC supply voltage and variation in load; the provision of such an inverter whose operating efficiency is very high; the provision of such an inverter which is relatively simple, having inexpensive construction and highly reliable.
[005]Also some of the available inverters do not have monitoring & controlling software interface. The problem faced by using these inverters is that when the battery goes low, it abruptly shuts down the inverter connected to it. This results in the loss of data & system failure. Further, some of inverters which claim to have monitoring & controlling software have the following drawbacks-
a) Existing monitoring & controlling software interface is not real time. They do not provide instantaneous values of the various parameters of the inverter and cannot do power audit. The product up-gradation is also not possible by these softwares.
b) In the inverters, where remote monitoring and controlling was possible, an additional card or hardware (SNMP and other like that) was to be connected to the inverter system. This increased the hardware as well as cost of the inverter.
c) Also these are positioned in a corner of the place, so that each and every time it becomes very difficult to monitor and check the parameters and accordingly change it.

[008]US publication no 20080215727 relates to a method for monitoring and reporting information regarding status of a power supply/management device operated by a user comprises detecting the status of the device using a monitoring device having an application interface configured to communicate over a communication network, generating a status update indication using a self-describing computer language and sending the status update indication over the communication network to a remote computer, and associating the user with the status update information for the remote device using the remote computer.

The invention power can monitor remote load normal connection status.
[010]Publication no 20070200434 and patent no 6,274,950 discloses uninterrupted power supply ("UPS") system which uses a battery communication system to communicate to a UPS processor information concerning the status of a battery pack in an array of parallel coupled battery packs. The battery packs provide back-up power for the UPS system. Information about the battery packs is collected by a monitor associated with each of the battery packs. The monitors measure battery pack voltage, currents and temperature and compile information about the battery pack from the measured values. Each monitor prepares data word representing information about its battery pack. The data words are transmitted to the UPS in response to commands issued by the UPS processor to the monitors.

[012]US publication no 20090231892 describes an uninterruptible power supply (UPS) system which includes an AC power input configured to receive AC power from a single-phase AC power source or a multi-phase AC power source, a DC power source, an output circuit including a power output, a controllable switch configured to selectively couple at least one of the AC power input and the DC power source to the output circuit, and a processor coupled and configured to affect operation of the output circuit depending upon which of single-phase and multi-phase operation of the UPS is indicated.
[013]The conventional system talks about the monitoring and controlling of the power backup systems from remote or local location. Some of the system describes the communication between battery bank and the power backup system. However, none of the system talks about the control of the power backup system through speech recognition/command which can increase the flexibility for the user and is safe in operation. Accordingly, there is a need in the art for a control strategy allowing for the use of an Inverter system that overcomes the aforementioned drawbacks. A means of efficiently operating power inverters, especially inverters featuring digital control is required, which allows greater flexibility and more precise control of the inverter and which can help in effective control of electric vehicle power source.
