This working model demonstrates the basic principles of a household circuit, showing how power flows from the power source (battery) to the connected appliances through switches.
Unfortunately, batteries generate direct current (DC). You can't just connect a battery directly to your home circuit board or your appliances. You need to convert the battery power into AC — commonly known as household electricity. The device that converts DC power to AC electricity is called an inverter.
In a circuit, the battery provides the power that flows through the wires to operate whatever devices are connected in the circuit. The battery is like a pump that pushes electrons around the circuit. Without a battery, there would be no flow of electrons and no current. Batteries are one of the most important components in a circuit.
Your home appliances use alternating current (AC) electricity to run. Unfortunately, batteries generate direct current (DC). You can't just connect a battery directly to your home circuit board or your appliances. You need to convert the battery power into AC — commonly known as household electricity.
A battery is made up of two or more cells that produce an electric current. The cells are connected together in series so that the current flows through them one after the other. This produces a voltage difference between the two ends of the battery, which is what powers the circuit.
A circuit is simply a path that electricity can flow through. It starts at a power source, like a battery, and then flows through wires or other conductors to an electrical load, like a light bulb. The current then flows back to the power source to complete the circuit.
The function of a battery in a DC circuit is to provide a source of voltage, or potential difference so that current can flow through the circuit. The most common type of battery used in household electronics is the lead-acid battery. This type of battery has two lead plates separated by an electrolyte solution (usually sulfuric acid).
When the battery is charged, lithium ions are generated on the positive electrode of the battery, and the generated lithium ions move to the negative electrode through the electrolyte. As an anode, the carbon is layered.

A Li-ion battery pack is composed of individual cells connected in series or parallel with a protective circuit module (PCM). The PCM is designed to protect the battery from overcharging, over-discharging, and excessive temperature. It is also responsible for monitoring the state-of-charge (SOC) of the battery.
The PCM is typically placed between the battery cells and the load. The Li-ion battery pack circuit diagram consists of three basic components: the battery cells, the PCM, and the load. The cells are the primary energy source for the system, providing the energy for the load.
