48V 30Ah (13S12P) Lithium-Ion Rechargeable Battery Description
A 48V 30Ah (13S12P) lithium-ion rechargeable battery is a high-capacity and high-voltage power source, widely used in demanding applications such as electric vehicles, renewable energy storage systems, and industrial equipment. Here is a detailed description of this battery configuration:
#### Specifications:
– **Nominal Voltage:** 48V
– **Capacity:** 30Ah (Ampere-hours)
– **Configuration:** 13S12P (13 cells in series, 12 parallel strings)
#### Configuration Explanation:
– **13S (Series):** The battery pack consists of 13 cells connected in series. Each lithium-ion cell typically has a nominal voltage of about 3.6V to 3.7V. When connected in series, the total voltage is approximately 48V (13 x 3.7V = 48.1V).
– **12P (Parallel):** Each series string is connected in parallel with 11 other identical strings. This increases the total capacity. If each individual cell has a capacity of 2.5Ah, then connecting 12 in parallel results in a total capacity of 30Ah (2.5Ah x 12).
#### Key Features:
1. **High Energy Density:** Lithium-ion batteries are known for their high energy density, providing a significant amount of energy storage in a compact and lightweight form factor.
2. **Long Cycle Life:** These batteries can endure numerous charge-discharge cycles (often between 500 to 2000 cycles depending on usage conditions), making them cost-effective over the long term.
3. **Efficiency:** High charge and discharge efficiency, typically above 90%, ensures that most of the stored energy is utilized effectively.
4. **Low Self-Discharge Rate:** Lithium-ion batteries have a low self-discharge rate, meaning they can retain their charge for extended periods when not in use.
#### Safety Features:
– **Battery Management System (BMS):** A BMS is integral to lithium-ion battery packs, providing critical functions such as:
– **Cell Balancing:** Ensures all cells charge and discharge evenly.
– **Overcharge/Over-discharge Protection:** Prevents the cells from being charged or discharged beyond their safe voltage range.
– **Short-Circuit Protection:** Prevents damage due to accidental short circuits.
– **Temperature Monitoring:** Protects against overheating by monitoring and regulating the temperature of the battery pack.
#### Applications:
– **Electric Vehicles (EVs):** Such as electric bikes, scooters, motorcycles, and small electric cars.
– **Renewable Energy Storage:** Home solar energy storage systems, enabling efficient use of solar power.
– **Uninterruptible Power Supplies (UPS):** Provides reliable backup power for critical systems.
– **Industrial Equipment:** Powering various types of industrial and commercial equipment that require robust and reliable energy sources.
#### Advantages:
– **High Performance:** Delivers consistent power output, suitable for high-demand applications.
– **Environmentally Friendly:** Compared to other battery chemistries like lead-acid, lithium-ion batteries have a lower environmental impact and are easier to recycle.
– **Lightweight:** Due to the high energy density, lithium-ion batteries are lighter than other battery types with equivalent energy storage, making them ideal for mobile applications.
#### Maintenance and Handling:
– **Proper Charging:** Use a charger specifically designed for lithium-ion batteries to avoid overcharging or damaging the battery.
– **Temperature Control:** Operate and store the battery within the recommended temperature ranges to prolong its lifespan.
– **Regular Inspection:** Periodically check the battery for any signs of damage or swelling and ensure connections are secure.
### Conclusion
The 48V 30Ah (13S12P) lithium-ion rechargeable battery is a versatile and powerful energy storage solution, combining high voltage and high capacity with advanced safety and efficiency features. Its robust design and long cycle life make it ideal for a wide range of applications, from electric vehicles to renewable energy storage and industrial equipment.
