Preamble to the Description
The following specification particularly describes the disclosure and the manner in which
it is to be performed.

TECHNICAL FIELD
The present disclosure generally relates to vehicle starting systems, and more particularly, to a charge booster for improving starting performance of a vehicle starting system.
BACKGROUND OF THE DISCLOSURE
The starting system is used of starting of the internal combustion engine of the automobile. The starting system in a vehicle mainly consists of a battery (Lead-Acid type), starter motor, ignition switch and a flywheel with ring gears by means of connecting starter motor to engine crank shaft for providing initial movement in engine. The insufficient charged lead acid battery when used for the starting of the engine, the starting performance of vehicle lead to erroneous starting or create the abrupt engine vibrations during cranking event.
In the current vehicle scenario when the battery SOC (State of Charge) is going below 80 %, then the starting of the engine can be troublesome because as the battery is getting discharged and starter motor is trying to draw heavy current to start the engine. So as the heavy current is getting drawn from battery its terminal voltage falls down drastically, that it will not sufficient for a starter motor to start the engine.
Such conditions may occur when the battery is discharge due to for a variety of reasons, such as, interior lights kept on whole night by mistake, prolonged non-usage of vehicle, heavy leakage current etc. Such conditions may occur rarely in the vehicle life cycle but certainly hitherto are not avoidable.
OBJECTS OF THE DISCLOSURE

The main object of this invention is to obviate the aforementioned drawbacks by
providing an improved supportive system for starting, which provides the mechanism to maintain the battery condition to healthy state to avoid low SOC cranks.
According to the present invention an improved supportive system for starting of engine comprising: a electronic controller unit, a ultra-capacitor bank, a IBS (Intelligent Battery System) sensor, a high current switching module, the electronic controller unit in the said system continuously monitor the battery health conditions with the help of IBS sensor so as to provide starting support by means of adding ultra-capacitor bank in the starting circuit while driver cranks the vehicle with a low SOC battery, the electronic controller unit also monitors the other vehicle parameters like, ultra-capacitor's charge, Engine RPM at starting to make logical decision to allow number of cranks with low SOC, charging actions for ultra-capacitor, warning messages to the driver.
The proposed system aid the degraded battery health by means of addition of the ultra-capacitor unit in parallel with vehicle power system. So when battery is below set threshold, electronic controller unit will add the capacitor bank in parallel with battery to share the load while engine starting. After the successful starting operation of the engine, the controller charges the capacitor bank to its maximum capacity, thus keeping it always at the healthy condition.
Further objects and features of the disclosure will become apparent from the following detailed description when considered in conjunction with the drawings.
SUMMARY OF THE DISCLOSURE
The embodiments of the present disclosure relates to engine starting system. The system helps in improving the starting performance of the engine while addressing the performance and durability issues of the vehicle aggregates (especially Powertrain aggregates) due to deterioration in performance of the starting system components like battery. The said system will aid in improving the starting performance by adding and

removing the capacitor bank, as and when required. This will ensure the required performance of starting system even when the battery condition is deteriorated, which otherwise would have affected the vehicle aggregates.

FIG. 2 illustrates a flow diagram of starting assisting system, in accordance with an embodiment of the present disclosure.
DETAILED DESCRIPTION OF THE DISCLOSURE
Referring now to the drawings wherein the showings are for the purpose of illustrating a preferred embodiment of the invention only, and not for the purpose of limiting the same, improved supportive system with the existing vehicle configuration.
The present invention discloses a starting assisting system 100 for an internal combustion engine (not illustrated). The starting system 100 comprising a rechargeable battery 10, a ultra-capacitor bank 12, a sensor 14; and an electronic controller unit 16 adapted to continuously monitor the battery 10 through the sensor 14; and a switching module 18 adapted to connect the capacitor bank 12 in parallel with the rechargeable battery 10 when the rechargeable battery health is sensed to be below a threshold. The switching module 18 may be a high current switching module. The sensor 14 may be an intelligent battery sensor (IBS). The threshold of the battery may be a low state of change thereof.
The electronic controller unit may be capable of also monitoring ultra-capacitor's charge, Engine RPM at starting to make logical decision to allow number of cranks with low

SOC. The electronic controller unit may therefore also trigger the warning messages about number of cranks available based on the ultra-capacitor's charge by visual/audio means. The visual/audio means may be located at the diver dashboard area. Any conventional display/audio alarm systems can be used to communicate the warning messages.
As per one embodiment of the present disclosure, a method of starting an internal combustion engine of a vehicle is disclosed. The method includes identifying status of vehicle battery in terms of O.C. (Open Circuit) voltage and the State of Charge SOC; calculating number of starts possible based on charge on ultra-capacitors bank, when the vehicle battery is identified as below a predefined threshold state of charge; system; communicating to the driver the number of possible starts; adding an ultra-capacitors bank in parallel with the vehicle battery. Communicating to the driver the number of possible starts includes displaying the numbers of starting by means of front panel indication on dashboard.
The method of starting an internal combustion engine further includes adding the ultra-capacitors bank into the vehicle system for charging of capacitors to the max capacity thereof, after successful starting of the internal combustion engine.
Referring now to FIG. 1, which illustrates the starting assisting system 100, the main Electronic Controller Unit (ECU) 16 controls the whole logic flow of the program/method. The typical ECU 16 is connected with the vehicle CAN and LIN network, for the information exchange on the network bus. On the CAN network, the ECU will receive information like, battery voltage at EMS ECU, Engine Speed, and on LIN network Battery terminal voltage, Battery current, SOC, Cell temperatures etc. On the basis of this information, ECU will process them and make the logical decisions as mentioned in Figure 2.
The basic working principle of the system is as follows: When the first IGNITION is made on in the vehicle, by means of ignition key lockset, all ECUs in the vehicle will get the wake-up signal and they start processing the available information.

Simultaneously ECU 16 of the system 100, also get wake signal and it starts monitoring health of the battery 10 in terms of O.C. (Open Circuit) voltage and the SOC. If the battery 10 SOC is above the set threshold voltage, the ECU will allow to start with normal starting process for engine starting. If the battery 10 SOC is below the set threshold, it will calculate the number of starts possible with addition of the ultra-capacitors bank 12 in parallel with battery system.
The same information, i.e. number of starting is conveyed to the driver by means of front panel indication on dashboard. So as the battery is below threshold level and addition of ultra-capacitors bank, the load is shared depending upon the battery condition.
If the vehicle is still not be able to start in first 2-3 subsequent cranks, the system will flash the warning messages to the driver that with addition of the supportive system it is not possible to start vehicle and take vehicle to the service point to avoid further damage to the system.
With the discharged battery with 70-80% of SOC, it is possible to start the vehicle in first attempt by using the said invented system. After the successful starting of engine, the said system's ECU will take decision for addition of the Ultra-capacitors bank 12 into the vehicle system for charging of capacitors to its max capacity. If the battery 10 SOC is falling below the second threshold voltage, here in this case 60%, the said system will decide the number of cranks possible or no cracking possible with the addition of Ultra-capacitor bank, and convey the information to the driver by means of warning lights and/or display messages on screen infotainment system.
The second threshold monitoring is necessary to isolate the battery as well as Ultra-capacitor bank 12 from vehicle starting system, to prevent the further damages to the vehicle system.
Advantages of the instant invention over the prior art are:
-The vehicle can be started at the worst case conditions.

-The addition of the said system will improve the vehicle battery life by keeping it to the healthy conditions.
-As the vehicle is starting with normal requirements all the time, there is less system failure which is prone to misbehave at starting.
-The said system will always gives the overall health of starting system to driver by means of dashboard information system and/or warning indicators.
-The system will also aid to the new start-stop system which are currently under development by many OEMs for Eco-friendly vehicles.
The foregoing description provides specific embodiments of the present disclosure. It should be appreciated that these embodiment are described for purpose of illustration only, and that numerous other alterations and modifications may be practiced by those skilled in the art without departing from the spirit and scope of the disclosure. It is intended that all such modifications and alterations be included insofar as they come within the scope of the disclosure as claimed or the equivalents thereof.
