That’s where lithium ion battery circuit diagrams come in. Understanding these diagrams can help you become better informed about how lithium ion batteries work to power your tech needs. A lithium ion battery circuit diagram is a map of the electrical systems of a cell battery that uses lithium ion battery cells.
In a lithium battery cell, a cathode and an anode are connected with an electrolyte material which helps the electric charge pass between the cathode and the anode. The circuit diagram shows how these components interact with each other to make the battery work effectively.
The charger circuit will be customized as per the battery specifications and the charging requirements. Regular 3.7 V Li-ion batteries have a maximum rated voltage of 4.2 V per cell. That means, when the terminal voltage of the battery reaches 4.2 V, it is fully charged and cannot store charge beyond that.
Typically, the terminals are located on either end of the battery. While legacy batteries typically have two terminals (one at the cathode and one at the anode), more recent batteries can have more than ten terminals. Figure 1 shows a battery diagram for an Li-ion battery.
To understand the diagram, one must look at the various elements, such as the diode, the resistor, the capacitor and the current limiter. For instance, the diode in a lithium ion battery circuit diagram helps in controlling the flow of charge from the battery to the device and back to the battery.
Regular 3.7 V Li-ion batteries have a maximum rated voltage of 4.2 V per cell. That means, when the terminal voltage of the battery reaches 4.2 V, it is fully charged and cannot store charge beyond that. In Constant Voltage state, the same voltage is applied at a constant rate by the charger circuit at the terminals of the battery.
