How Do Series and Parallel Configurations Impact Hybrid Battery Voltage?
Series and parallel configurations significantly impact hybrid battery voltage by determining how voltage adds up or remains constant across the battery system.
In a series configuration, multiple battery cells connect end-to-end. Each cell adds its voltage to the total. For example, if each cell has a voltage of 3.7 volts and there are four cells in series, the total voltage would be 14.8 volts (3.7 V x 4). This configuration benefits hybrid vehicles by providing higher voltage for electric motors, thus enhancing performance.
In a parallel configuration, battery cells connect side-by-side. The voltage across each cell remains the same, while the capacity (amp-hours) increases. For instance, if two cells of 3.7 volts and 2000 milliamp-hours connect in parallel, the total voltage remains 3.7 volts but the overall capacity doubles to 4000 milliamp-hours. This setup is advantageous for extending runtime and providing a steady voltage supply without increasing the risk of overvoltage to the system.
The choice between series and parallel configurations influences the battery’s performance characteristics such as:
- Voltage output: Series connections increase voltage, allowing for higher power delivery.
