Q & A

What is the main purpose of the video created by Muhammad Haleem?

The main purpose of the video is to demonstrate how to convert a 12-watt battery into a 220-volt power source that can run most household appliances without needing a UPS or inverter, except for two specific exceptions.

What are the two appliances that cannot be run using the battery system described in the video?

The two appliances that cannot be run using this battery system are a water motor and an old fridge fan. However, AC/DC fans and DC inverter fridges can be operated.

How many cells are needed to create a 231-volt battery as per the video, and what is the voltage of each cell?

A total of 55 cells are needed to create a 231-volt battery, with each cell having a voltage of 4.2 volts.

What is the role of the BMS (Battery Management System) in the battery setup?

The BMS is used for protection against overcharge and overdischarge by cutting off power when the voltage drops too low or goes too high. It also helps in balancing the cells to ensure even charging and discharging.

How is the battery charged according to the video?

The battery is charged using a bridge rectifier made from diodes (model 4007), along with a 10 microfarad capacitor. This setup is connected to the main power supply (WAPDA) to charge the battery.

What safety precaution is mentioned regarding handling the battery setup?

It is mentioned to be careful not to touch the connections with both hands while the system is live, as it could deliver a significant electric shock.

Why is it important to use cells from the same company when building the battery?

Using cells from the same company ensures that the cells have similar capacities and performance characteristics, which is important for the longevity and efficiency of the battery system.

What does Muhammad Haleem suggest doing before assembling the cells into the battery?

He suggests checking each cell with a meter to ensure they have similar voltages and charging all the cells fully before assembly to ensure they start at the same charge level.

What is the significance of using a diode bridge in the charging process?

The diode bridge rectifies AC power from the main supply to DC to safely charge the battery. It ensures that the current flows in the correct direction to the battery.

What is the charging capacity mentioned for the battery system, and how can it be increased?

The charging capacity mentioned is between ten to fifty or sixty watts. It can be increased by connecting more bases to the charging setup for faster charging.
