36V 10Ah (10S4P) LITHIUM-ION RECHARGEABLE BATTERY
A 36V 10Ah (10S4P) lithium-ion rechargeable battery is a configuration that combines lithium-ion cells in series and parallel to achieve a specific voltage and capacity. Here’s a detailed description:
### Configuration
1. **10S (Series)**: This indicates that 10 cells are connected in series. Each lithium-ion cell typically has a nominal voltage of 3.6V to 3.7V. Connecting cells in series adds up their voltages.
– **Total Voltage**: 10 cells * 3.6V = 36V (nominal), which is why it’s referred to as a 36V battery.
2. **4P (Parallel)**: This means 4 sets of the series-connected cells are connected in parallel. When cells are connected in parallel, their capacities add up.
– **Total Capacity**: If each cell has a capacity of 2.5Ah (10Ah / 4), then 4 cells in parallel give a total capacity of 10Ah.
### Specifications
– **Voltage**: 36V (nominal), which is the combined voltage of 10 cells in series.
– **Capacity**: 10Ah, achieved by connecting 4 sets of cells in parallel.
– **Energy**: The energy capacity can be calculated as Voltage * Capacity. For this battery, it would be 36V * 10Ah = 360Wh.
– **Cell Type**: Typically, lithium-ion cells such as 18650 or 21700 cells are used in these configurations.
– **Configuration**: 10S4P, meaning 10 cells in series and 4 parallel sets of these series-connected cells.
### Applications
This type of battery is suitable for applications requiring a moderate balance of high voltage and capacity, such as:
– **Electric Bicycles and Scooters**: Providing the necessary power and range.
– **Portable Power Tools**: Offering extended runtime for cordless tools.
– **Solar Energy Storage**: Storing energy from solar panels for later use.
– **Uninterruptible Power Supplies (UPS)**: Ensuring continuity of power during outages.
– **Electric Drones and Robots**: Providing a reliable power source for extended operations.
### Advantages
– **High Energy Density**: Lithium-ion batteries offer a high energy density, making them suitable for space-constrained applications.
– **Long Cycle Life**: These batteries can endure many charge and discharge cycles, making them cost-effective over time.
– **Low Self-Discharge**: Lithium-ion batteries have a relatively low self-discharge rate, maintaining charge for longer periods when not in use.
– **Lightweight**: They are significantly lighter compared to other types of rechargeable batteries like lead-acid batteries.
### Safety Considerations
– **Battery Management System (BMS)**: Incorporating a BMS is crucial to protect against overcharging, over-discharging, and short circuits. The BMS also helps balance the cells, ensuring longevity and safety.
– **Handling**: Avoid physical damage, puncturing, or exposing the battery to extreme temperatures. Lithium-ion batteries can be hazardous if mishandled.
### Charging and Discharging
– **Charging Voltage**: The typical charging voltage would be around 42V (4.2V per cell * 10 cells).
– **Charging Current**: The charging current should be within the recommended range specified by the cell manufacturer, often between 0.5C to 1C of the battery’s capacity.
– **Discharge Cutoff Voltage**: The cutoff voltage for discharge is usually around 3.0V per cell. For a 10S battery, this would be 30V.
### Summary
A 36V 10Ah (10S4P) lithium-ion rechargeable battery is a reliable and efficient power source for various applications, combining high voltage and moderate capacity in a compact and lightweight form. Proper usage and maintenance, including the use of a BMS and careful handling, ensure optimal performance and longevity.
