PROBLEM STATEMENT
In worldwide most of cars do not have any indication of the battery voltage level and any alert to the driver if the battery is very low. Therefore if the car is off parked and the battery is drained completely for any reasons, the user cannot be able to start the car. This may cause a lot of inconvenience to the car driver and other user
MAIN OBJECTIVES
The general objectives of this project is to design and implement a real time car battery status with low voltage alert and solar backup system.
SPECIFIC OBJECTIVE
- To design and implement a power supply unit with solar and battery charger.
- To design and implement a control circuit.
- To provide a voltage sensor.
- To provide a displaying unit.
- To build the prototype.
- To test and troubleshoot the system.
LITERATURE REVIEW
Existing system
In previous project of car battery monitoring system uses a qualitative parameter that indicate the ability of the battery to deliver the charge that is stored in it. The indicating parameters was just used to indicate if the battery is fully charged, safe to use mode or battery voltage level is extremely low that lead to incapable of starting the car. There was no any indication in percentage of voltage level indicate to alert the user or no any alerting system of low voltage level.
Disadvantages of existing system
- Does not alert the car user in case they forget to switch off anything which may drain the battery after parking.
- Reduces the life span of the car’s battery
- Reduces the life span of the alternator
- Disposal of battery lead to environmental pollution.
Operation of proposed system
According to the block diagram the battery will produces power to the voltage sensor and also check the level of voltage of the battery. In which the voltage sensor detect the level of voltage and send information to the microcontroller. Microcontroller will control the voltage level and make the LED indicator to indicate the controlled level, under low voltage level of car battery at the certain level. The relay will disconnect the load which consist of lighting system radio and air
The relay will disconnect the load which consist of lighting system radio and air condition in order to prevent the continuing drop of voltage and the alarm circuit consist of buzzer will alert the user and prevent the user from not being able to start the car. Also after the relay disconnecting the load, voltage from the solar panel will be regulated by power supply for battery charging and also powering the whole circuit.
Analysis of LED
To calculate the value of resistance
Nominal current = 10mA -16mA ( obtained from data sheet)
Forward voltage (Vd) =1.8V- 2.4V(obtained from data sheet)
Let D4=D5=D6=D
Vd = 1.8V
R3=R4=R5=R
From ohms law
VS=IR + Vd
R=(5𝑉−1.8𝑉)/10𝑚𝐴=320Ω
A standard resistor value of 330Ω was chosen since it was the nearest lowered preferred value.
Analysis of Buzzer
To calculate the value of resistance R2
Resonant frequency: 2300Hz
Rated voltage =5V DC(from buzzer data sheet)
Rated current =30mA (from buzzer data sheet)
From V =IR2
R2 = 𝟓𝑽/𝟑𝟎𝒎𝑨 =166.7Ω
A standard resistor value of 200Ω was chosen since it was the nearest lowered preferred value.

ReplyDeleteOverall, there is no casino that is 여주 출장마사지 as close to a 삼척 출장안마 $20 minimum deposit as a regular player, but that is not much. The overall 하남 출장안마 casino experience is pretty impressive 포천 출장마사지 and 전라남도 출장샵

I just have to introduce this hacker that I have been working with him on getting my credit score been boosted across the Equifax, TransUnion and Experian report. He made a lot of good changes on my credit report by erasing all the past eviction, bad collections and DUI off my credit report history and also increased my FICO score above 876 across my three credit bureaus report you can contact him for all kind of hacks . Email him here support@wavedrive.tech go on their website wavedrive.tech for more details,Whatsapp No:+14106350697 if you want to chat them up,One thing i can assure you would not regret this at all he is 100% legit
