Furthermore, the modulator 103 for battery management by controlling the switching of battery module 101, 102 using control switch 107 by generating a trigger. The switch trigger 107 changes vehicle power source from electric 102 to solar 101 on the basis of required power by the vehicle. The switch 107 also change back the battery source form solar 101 to electric 102 after charging of electric battery. The switch 107 is turned ON/OFF by the control of the modulator 103 and switching ON/OFF the batteries of the battery modules 101, 102 at multiple positions. For example, when the electric battery is unable to provide the charge or the electrical need of the vehicle; the switch 107 automatically changes the power source with an indication to the driver that the battery has in issue.

In an embodiment, the modulator 103 selects the number of batteries of battery module on the basis of power requirement of the vehicle at a time instance.

In other embodiment, the total number of batteries in battery power source 101, 102 are even in number.

Additionally, the control switch 107is a manual switch having dual position i.e electric battery 102 to solar battery 101 and vice versa. The switch 107 selects a battery module 101 or 102 for running vehicle utilities. The switch 107 either connects the utilities with electric power source 102 and disconnects the solar power source 101 or connects the utilities with solar power source 101 and disconnects the electric power source 102.

In an embodiment, the power source 101, 102 can be changed by user input via vehicle computing system 108.

In another embodiment, the electric power source 102 can be fully disengaged by the user from the power terrain.

The control switch 107 is working as ON and OFF while the car is switched in battery mode 101 and will function as ON when the car is running on electric power source 102 and will be OFF as soon as car is runs on solar power source 101.

In an embodiment, the switch 107 is having multiple sub-switches to switch ON/OFF of the batteries of battery modules using solar 101 and electric power source 102.

However, the vehicle will run for a shorter distance and has a certain speed limits as the solar power 101 is used as backup power source, it may not let the vehicle to extract the full power.

Further, in terms of performance, all the features of the vehicle will function normally till the solar panel has sufficient charge. Once the range of 20 km is left in pad again the charging box comes into play to stabilize the car in a proper reserve mode. Thus, every extra feature on car shuts down as the charging needs to be conserved to help the people, cover more distance than expected to find a proper charging station.

In other embodiment of the present disclosure, the power plug 110 of car is different sort of plug with a rectangular design. The slot will be in the front side of car on the co-passenger side and will automatically detect the chargers and represent the charge in the dashboard. As soon as the car is full charged, the plug will automatically eject the charger backward to such an extent that it loses contact to the main charging mechanism and it will only be hanging or jam into the charging port with an actual contact to the mechanism. Power plug 110 may also enable playing of audio while charging and will have a function that will depict the charging status.

In another embodiment of the present disclosure, the power out are been carried in a smart way that switches the power between electric source 102 and solar source 101. The power output will be normal until the power of the solar battery 101 reaches approximately to the 30 percentage of the total power. Thus, all the features of the vehicle may stop working other than information display of tacometer and speedometer, so as to ensure that the person driving the car reaches nearby charging station. As soon as the vehicle is charged the solar power will automatically start charging again and will provide as a backup source.

Further, the modulator 103 is connected to a sensor 104 to sense a battery consumption data of batteries of power sources 101, 102 and send the data to the modulator 103. The modulator calculates the battery consumption rate. If the power consumption by the port of any other extra utilities is causing an effect on the battery pad or the solar backup 101 (as per the source used at that time) the sensor 104 shows the warning on dashboard. Accordingly, the driver turns off that port or stops the work if the battery power is needed for long run. The warning given, if ignored can cause no harm to battery but it is just reminder pertaining to the efficiency of the car which may be affected in long run plan.

Further, the battery modules 101, 102 serves to measure the status of the batteries in the power sources 101, 102, such as power requirement, temperature, and power consumed etc., and to control and manage the power source 101, 102 and the entire batteries based on the measured information. In particular, the modulator 103 serves to switch the power source 101, 102 and change a battery composition of battery module based on the power requirement of the vehicle to run amenities. The modulator 103 switches the modules 101, 102 to cool the battery and avoid any hurdle. Here, the temperature sensor 402 measure the temperature of the power sources 101, 102 which is running for safety. The sensor 402 helps in keeping the battery module 101, 102 cool. The power sensor 401 sense the power requirement of vehicle utilities. And the power consumption sensor 403 sense power consumed data from the batteries of battery module/power sources 101, 102. The sensors in the vehicle improves the battery efficiency rate with lower risk. The status of the batteries of power sources 101, 102 decide battery composition of the battery module to run the amenities.

Battery Composition means combination of the batteries of battery modules 101, 102 for proper functioning of a vehicle during travel. The composition can be made by functioning of a power source at a specific time or both power sources at the same time. When one of the battery module/power source is functioning, then currently used battery module can be switched off and Switch on the standby battery module. Also one of the batteries of the battery module working currently can be switched off and other batteries of same battery module or other batteries of standby battery module can be switch on. In other scenario, when both the battery modules are functioning. One of the battery modules can be switched off or switch off one battery of any or both battery modules currently functioning and switch on other battery of any or both battery modules.

In an embodiment, the silicon composition of battery helps the vehicle to become fire proof.

Moreover, the modulator 103 serves to transmit the status information and various information of the entire batteries to a vehicle computing system 108 mounted in the vehicle. The vehicle computing system 108 includes a human computer interface to receive user input regarding the switching module. The system generate a trigger using control switch 107 which is received and processed by the modulator 103. The user input may ON/OFF any battery module 101, 102 or any battery of any of battery module. The input may also switch a battery module to another or switch a battery of battery module with other batteries of battery module. The modulator 103 also transmits mode switching information to the vehicle computing system 108 such that a user of the vehicle can identify the mode of battery module using human user interface.

As per Fig.l, the inverter 105 is used to convert DC power in to AC power and AC/DC generator generate AC-DC power. Further in fig.2, the novel design of an electric battery consists of 7 rows and 5 columns charging pad, made up of lithium core battery. It is aligned in such a manner that they discharge one by one which causes minimum energy losses. The battery is provided with an extra insulation coating as protective gear and thus reduces the heat and electron loss while radiation.

Figure 3 shows charging pad of electric battery having unit charging together and discharging one by one. During charging, all the batteries may be charged together as a whole unit and thus utilize less time while charging. The charging pad consist of 7 rows and 5 columns (shown in Fig. 2) with a wire attached to each of its row for specific discharging with an unique order whereas the charging function or the charging wire will be attached to each of its column for the better efficiency of charging with respect to time consumption. The charging pad is made of anodized aluminum and plastic material with an extra coating of polymer to ensure that the heat loss is less from the battery.

The charging pad or the main battery of the automobile has 35 wires for charging and 5 for discharging to achieve better efficiency while charging with respect to time. The vehicle runs for a longer distance as the battery pad will not be activated all at once.

In other embodiment of the present disclosure, the battery pad includes smart feature of shifting automatically to electric or solar energy according to the power required by the vehicle. The battery is placed at the rear side, in the middle portion at the above of the shaft for the better stability of the vehicle. Once the battery pad is active it may lead to high electric powered access to the car including tons of features, thus adding to the comfort level at the lower price point. In yet another embodiment of the present disclosure, when the certain limit of one whole unit is reached, the successive battery comes into play leaving aside the used battery pad.

Further, the shift in the battery pad is achieved through a certain amount of wire with an indicator to shift the battery in a smart way further to have smooth experience. The whole unit of the automobile gives an output of approximately 1200km.

In further embodiment of the present disclosure, the battery is protected from any possible harm and also to reduce the power loss which may be in the form heat form or the radiation or electron loss so as to provide better efficiency and long life. It is protected by a thick coating of thick polyster covering every cut and creases of the battery wire and all the connectional space with and optimum space to let the wire a free run through the car. The insulation pad (shown in Fig. 2) helps in reducing the heating factor and the heat losses.

Further, Fig. 4 shows the plugging system 400. The battery modules 101, 102 are plugged to the power source using a plugging mechanism. The plugging mechanism includes sensors such as power sensor 401 , temperature sensor 402, and power consumption sensor 403 to detect their status information such as power level of each battery of battery modules and their temperature. The plugging mechanism all includes a microcontroller 404 to receive and process the power level of battery modules. The microcontroller 404 compares the power level with a standard power level of battery modules. The mechanism cuts the power supply from the vehicle power terminal 405 when the current battery power level is beyond the expected level. Otherwise retract the plugging mechanism from an electric pin connector of their respective power source.

Furthermore, the running power of car is improved because of new design of battery. The power factor may be 13.5 or 13 kwh/km, as the new battery emits less heat in terms of the existing batteries.
