48V 15Ah (13S6P) LITHIUM-ION RECHARGEABLE BATTERY
A 48V 15Ah (13S6P) lithium-ion rechargeable battery is a configuration of lithium-ion cells designed to deliver a specific voltage and capacity for various applications. Here’s a detailed description:
### Configuration
1. **13S (Series)**: This indicates that 13 cells are connected in series. Each lithium-ion cell typically has a nominal voltage of around 3.6V to 3.7V. Connecting cells in series adds up their voltages.
– **Total Voltage**: 13 cells * 3.6V = 46.8V (nominal), typically labeled as 48V for convenience.
2. **6P (Parallel)**: This means 6 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 (15Ah / 6), then 6 cells in parallel give a total capacity of 15Ah.
### Specifications
– **Voltage**: 48V (nominal), which is the combined voltage of 13 cells in series.
– **Capacity**: 15Ah, achieved by connecting 6 sets of cells in parallel.
– **Energy**: The energy capacity can be calculated as Voltage * Capacity. For this battery, it would be 48V * 15Ah = 720Wh.
– **Cell Type**: Typically, lithium-ion cells such as 18650 or 21700 cells are used in these configurations.
– **Configuration**: 13S6P, meaning 13 cells in series and 6 parallel sets of these series-connected cells.
### Applications
This type of battery is suitable for applications requiring a balance of high voltage and moderate to high capacity, such as:
– **Electric Bicycles and Scooters**: Providing ample power for extended rides.
– **Electric Vehicles**: Small electric cars, motorcycles, and scooters.
– **Solar Energy Storage**: Storing energy from solar panels for later use, especially in off-grid systems.
– **Uninterruptible Power Supplies (UPS)**: Providing backup power for critical systems during outages.
– **Electric Boats and Golf Carts**: Powering electric propulsion systems for leisure and transportation.
### Advantages
– **High Energy Density**: Lithium-ion batteries offer a high energy density, providing more power in a compact size.
– **Long Cycle Life**: These batteries can endure numerous charge and discharge cycles, making them durable and cost-effective over time.
– **Low Self-Discharge**: Lithium-ion batteries have a relatively low self-discharge rate, retaining charge when not in use for extended periods.
– **Lightweight**: Compared to other battery types, lithium-ion batteries offer high energy density per unit weight.
### Safety Considerations
– **Battery Management System (BMS)**: Essential for managing and protecting the battery against overcharging, over-discharging, and short circuits.
– **Proper Handling**: Avoid physical damage, puncturing, or exposing the battery to extreme temperatures, which can lead to safety hazards.
### Charging and Discharging
– **Charging Voltage**: The typical charging voltage would be around 54.6V (4.2V per cell * 13 cells).
– **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**: Typically around 39V (3.0V per cell * 13 cells).
### Summary
A 48V 15Ah (13S6P) lithium-ion rechargeable battery offers a balance of high voltage and moderate to high capacity, making it suitable for various applications where reliable and efficient power is required. Proper usage, maintenance, and safety precautions ensure optimal performance and longevity of the battery.
