A MOBILE OFF-GRID POWER SYSTEM AND METHOD THEREOF
Field of the Invention
This invention relates to delivery of GREEN power solution delivered at remote locations as a MOBILE solution - collectively called Mobile Off -grid Power System and method. Particularly, the present invention provides the generation and distribution of multiple Green Power using multiple sources of power: Solar, Wind and Hydel power generated and distributed through easily movable, sustainable off -grid power system.
Background of the Invention The following background discussion includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art. In recent years, number of electric vehicles plying on the road has increased manifold. Further, it expected that there will be a significant increase in the number of EVs in the near future. Thus, there is an increased requirement f for electric power charging. As a result, the existing electric power grid infrastructure, which includes utility power grids, distribution power grids and power grids at a residential or commercial level, are very likely to face challenges to satisfy the increased charging requirements.
Further, the automotive industry has standardized a variety of charging methods for EVs. These methods include AC and DC charging methods. AC methods tend to be more universal within a country than DC methods. In AC charging, AC power is sent to the EV, which contains a charger and energy storage (e.g., a battery). The charger in the EV is designed specifically for the battery of the EV and charging control electronics are contained within the EV. AC charging, however, has a limited ability to charge a battery quickly due to power limits. It is also considered a RED solution, contributing to the carbon generation in the country, offsetting some of the advantages of Electric Vehicle related savings.
To solve the problem of quick charging, DC charging is proposed. Although, DC charging is more complex than AC charging, yet may provide for much faster charging. DC chargers are external to the EV, such that DC charging requires more communications and power control between the charger and the battery than AC charging. Unlike in AC charging where the voltage is defined by the power utility, DC charging methods may be unilaterally defined by an EV manufacturer. To address the interoperability issue, DC charging standards have been developed. The standards specify multiple charging rates. For example, as shown in the table below, Level 1 charging allows for AC or DC charging and the DC charging option can deliver 4 to 40 kW, and Level 2 charging can charge DC-only from 10 to 100 kW. The more energy delivered to the battery, the faster it can be charged, within the
3
limits of the specific battery's chemistry. Our invention allows variation in the level of charge being generated and absorbed
Further, apart from availability of the type of the charging point for the EV vehicle, dearth of the charging station at the different place along the roads are main concern to the EV vehicle owner. The availability of the charging station greatly decides the movability of the EV in the area. Although, charging station are increasing in the number along the roads in several area but there are several constraints. Usually, charging station draws power of the conventional grid system for its power requirement. Additionally, due to the specific power requirements of the charging station all conventional Ac power does not supports the charging station; this limits the installation of the charging station at the specific place where the conventional power system suits the charging station. With the Central Government’s mandate to substantially increase the production and deployment of EV vehicles on Indian roads over the next 20 years, this issue will compound and requires an innovation that can address this demand and supply gap and technology gaps
To solve the above problem, hybrid charging station was proposed. For instance, patent application No. P-398332 discloses an electric method of summing up the distributed wind energy consisting of in that those voltages of a plurality of small wind power generators situated close with respect to each other are connected electrically in series creating thus an AC bus grid terminated with a receiving-converting-generating station with power equaling the sum of powers of the individual wind power generators. The receiving-converting-generating station is a station in which the power of the supplied direct current is transformed, by means of a converter, into power of alternating current with parameters consistent with parameters of the national power grid. This is one of the core components of the integrated system that is the subject of this innovation
Further, CN 104092236 discloses a solution entitled "Hybrid renewable energy, a system of supplying from renewable energy sources, and a system of control and thereof' consisting in that the renewable energy sources, which can be photovoltaic generators and wind power generators, are connected to a common DC voltage line which is coupled bi directionally with a converter converting DC electric energy into AC electric energy, such converter being in turn coupled bi directionally with an AC voltage line transmitting the electric energy to the main electric power grid, whereas said line is coupled bi directionally with a device-accumulator storing the AC electric energy, and moreover said AC voltage line can be additionally supplied from other renewable sources DC electric energy converted into alternating current.
Further, US2012 0019203A1 discloses invention providing energy storage and a vehicle charging system for a substation on an electrical power network with an energy storage system coupled to receive and store electrical power. The stored electrical power may then be used to either charge vehicles or meeting the needs of other discretionary or interruptible loads. The idea of the invention consists in that
4
the energy storage system comprises an energy distribution facility having at least one energy input and a plurality of energy outputs, and an energy storage device coupled to said at least one energy input and at least one of said plurality of energy outputs. Further, a charging station is associated with said energy distribution and configured to removable couple said energy storage device in one or more electric vehicles, said charging station being geographically proximate to said energy distribution facility and electrically coupled with an inverter or motor generator set.
Thus, there is need for an off -grid power system and method which can be employed remotely at remote places and able serve variety of power demand of the user.

In an embodiment, the system of the present invention includes a Solar cell panel, direct current DC converter, contact switch module (can integrate to in the direct current DC converter), power battery module, battery management system, on-vehicle two-way charger and vehicle control unit. The direct current converter, the battery management system, the charger and the vehicle controller are communicated and exchange information through a vehicle Controller Area Network (CAN) bus.
In an embodiment, the battery management system can measure and calculate the residual electric quantity and the state of health of each power battery module and the residual electric quantity of the whole battery pack and sends the information through controller area network communication.
In an embodiment, the input voltage range of the direct current converter covers the lowest voltage to the highest voltage of the Solar panel, and the output voltage range of the direct current converter covers the lowest voltage of the 12V low-voltage battery to the highest voltage of the power battery. The DC-DC converter can automatically identify the voltage of the battery terminal connected to the output end and automatically adjust the output voltage, and a maximum power point tracking control method is used for charging the battery module or the battery pack at the output end by using Solar energy.
As shown in fig. 1, the present invention includes a Solar panel 101, a dc-dc converter 102, a contact switch module 103, power battery modules104, 105, and 106 (taking three power battery modules connected in series as an example), a battery management system 107, the battery management system 107.
In an embodiment, when the battery management system 107 detects that there is low level of the battery power, then through CAN communication and informs that the power battery CAN be charged through Solar energy at the moment. The battery management system 107 measures and calculates the residual electric quantity of each power battery module 101, 102 and 103.

In an embodiment, the adoption of Charge Controllers for Wind and Hydro with our Inverter/Controller, A charge controller for a wind-electric or hydro-electric charging system must protect batteries from overcharging, just like a PV controller. However, a load must be kept on the generator at all times to prevent overspeed of the turbine. Instead of disconnecting the generator from the battery (like most PV controllers) it diverts excess energy to a special load that absorbs most of the power from the generator called dummy load/brake resisters. That load is usually a heating element, which “burns off” excess energy as heat.
In an embodiment, the solar-powered inverter unit of the present invention consists of chain connections. The chain connection in which solar panel is connected to a charge controller. The primary function of the charge controller is to protect the battery bank from overcharging. This is done by monitoring the battery bank- when the bank is fully charged, the charge controller sends energy from the filled battery bank to a (diversion) load. The battery stores up charges and is connected to the inverter. The function of the inverter is to translate the Direct Current (DC) power supply from the battery to an Alternating Current (AC) power supply- the usable form for home or office appliances. The inverter is connected to the energy meter. The energy meter measures the load of the inverter. The energy meter used is the to measure the voltage, current, power, energy, frequency Power factor (frequency and PF is extra added in the new version) using a microcontroller unit. The Mcu

It can be connected with other datas like weather, radiation, etc. The Charge controller is connected between the solar panel and the battery to regulate the power coming from a solar panel with the right voltage and current before going into the battery through Even PCU. It regulates the fluctuating output of the solar panel at any point be it at the sun’s high intensity or low. To ensure that batteries do not overcharge during the day and that power does not run back to the solar panel overnight and drain the batteries. The DC output from the battery will be sent into the inverter which does the conversion from DC to AC and to supply to the AC loads. The output from the inverter gets fed into the energy metering system (Sensors) and the Mcu board, which serves as the control unit and finally to the various loads connected to the system. The Wi-Fi module present in the Mcu hooks the system to the internet over a Wi-Fi connection using the gateway. The data which includes the value of voltage, current, power, energy of input/output/solar/battery data, the battery level of the inverter can be accessed via the mobile application interface. It can then be monitored and controlled remotely.
