DESC:FIELD OF INVENTION
[0001] The present disclosure relates to the field of power backup systems and, more particularly relates to an IoT based system for fast charging of a battery that efficiently utilizes solar energy, while maintaining a battery life cycle.
BACKGROUND OF THE INVENTION
[0002] Industrial, commercial, and residential buildings, utilize electrical power primarily from a municipal power supply grid. However, the use of alternative supplies of power is becoming widespread. These alternative supplies of power include, for example, green energy sources such as photovoltaic (PV) cell arrays, wind farms as well as fossil fuel generators. As these alternative supplies of power may be insufficient to fully satisfy the energy requirements, it is often necessary to employ a mixed-approach to energy consumption whereby green energy sources are used to the extent available. The municipal power supply grid may be relied upon to compensate for the difference between the supply of power from the green energy sources and the energy demanded by the facility.
[0003] Even after modernization of power supply resources, the Lead acid batteries in use take time for charging. A normal lead acid battery can take up to 10 hours for charging. With development and introduction of Lithium batteries that take comparatively less amount of time for charging, the problem of fast charging is addressed. However, due to fast charging, the battery life cycles of Lithium battery are reduced. Further, due unavailability of solar energy during night or during rains, the charging of Lithium battery is solely done by mains power supply or the grid supply, which is not economical viable.
[0004] In addition to the above, even though the conventional OFF grid or ON-grid systems using a solar charge controller along with a battery management system (BMS) are able to manage power supply from the grid and photovoltaic (PV) cells, the conventional OFF grid or ON-grid systems are not flexible in terms of providing an option for charging a battery using solar energy till a certain level and thereafter diverting a part of solar energy to run load(s), even while charging the battery or diverting all solar energy to run load(s), as per requirement of a user.
[0005] Therefore, there is exists a requirement of an IoT based system for fast charging of a battery that efficiently utilizes solar energy, while maintaining battery life cycle.
OBJECTIVES OF THE INVENTION
[0006] The present disclosure relates to provide an IoT based system for fast charging of a battery.
[0007] It is another object of the present disclosure to provide the IoT based system for fast charging of the battery including a central server, an inverter with a battery management system (BMS) in electronic communication with the central server, a solar charge controller in electronic communication with the BMS and the central server, a solar panel in electronic communication with the solar charge controller, a current transformer (CT) connected to grid supply to detect amount of supply from the grid and in wireless connection with the central server, and a battery bank.
[0008] It is another object of the present disclosure to provide the IoT based system capable of manipulating solar energy in accordance with a charging algorithm, to charge the battery bank using solar energy till a certain level and thereafter diverting a part of solar energy to run load(s), even while charging the battery or diverting all solar energy to run load(s), as per requirement of a user.
[0009] It is another object of the present disclosure to use the IoT based system for charging the battery of an electric vehicle (EV).
[0010] These and other objectives and advantages of the present disclosure will become more apparent when reference is made to the following description.

[0028] In an embodiment, the provision for manipulating charging the battery bank includes a plurality of battery charge levels. The plurality of battery charge levels can be 10% or 20% or 30% etc., as per the load requirement or as per the command by the user using the platform.
[0029] In an embodiment, the pre-set charge level of charging the battery bank 114 is in the range of 10% to 99%.
[0030] In an embodiment, upon reaching a pre-set level of battery charge, the processing unit compares the current reading provided by CT 110 and solar energy being supplied by solar panel 140, and diverts a part of solar energy to grid or all of solar energy, as per load requirement and an input command by the user.

[0032] In an embodiment, upon reaching the pre-set level of battery charge, the processing unit compares the second value provided by CT 110 and first value by the solar charge controller 108, and diverts a part of solar energy to grid 160. Therefore, the IoT based system 100 of the present disclosure is advantageous in terms of saving on the bill by suppling solar energy to grid, while maintaining a battery life cycle.
[0033] In an embodiment, the IoT based system 100 of the present disclosure can be used for charging a battery of an electric vehicle (EV).
