48V 100ah Low-Voltage Lithium Iron Phosphate Battery

Product Description

Application Scenarios

The 48V 200Ah low-voltage lithium iron phosphate battery (hereinafter referred to as "the battery") has the characteristics of strong voltage adaptability, large capacity (48V × 200Ah = 9.6kWh), high safety (stable chemical properties of lithium iron phosphate), and long cycle life (usually more than 2000 times). It is widely used in various low-voltage energy storage and power scenarios, as follows:

I. Energy Storage Field

1. Residential Energy Storage Systems
   • It is used with solar photovoltaic panels to store the electricity generated during the day for household use at night or during power outages, realizing "self-generation and self-consumption" and reducing dependence on the power grid.
   • It is especially suitable for remote areas, areas with unstable power grids, or families pursuing green energy.
2. Small Commercial and Industrial Energy Storage
   • It is used in places such as shops and small factories. It is charged during the low electricity price period and discharged during the peak period (peak-valley arbitrage) to reduce electricity costs. At the same time, it can be used as an emergency power source to deal with short-term power outages.
3. Backup Power for Communication Base Stations
   • It provides stable backup power for communication base stations in remote areas, ensuring that the base stations can work normally when the power grid is cut off (usually need to be used with an inverter) to avoid communication interruptions.

II. Power Field

1. Low-Speed Electric Vehicles
   • Including electric tricycles (for freight and passenger transport) and electric four-wheelers (elderly scooters, scenic spot sightseeing vehicles, factory commuter vehicles, etc.). The 48V voltage is compatible with the motor systems of these vehicles, and the large 200Ah capacity can support a long range (usually 100-200 kilometers, depending on the vehicle load and speed).
2. Special Operation Vehicles
   • Such as golf carts, airport luggage tractors, and short-distance port transporters. These vehicles have low speed requirements but high requirements for range and battery stability. The long life and safety of lithium iron phosphate batteries are more suitable.

III. Other Scenarios

1. Power Supply for Outdoor Mobile Devices
   • It provides power for field operation equipment (such as geological exploration instruments, camping RV power supply systems, mobile medical stations) to meet the power demand when away from the power grid.
2. Backup Power for Security Monitoring Systems
   • It provides uninterrupted power for security cameras, alarm devices, etc. in remote areas to ensure that the monitoring system can still operate during power outages.
3. Power Supply for Agricultural Equipment
   • Such as small electric irrigation equipment and UAV charging stations (used as energy storage power sources to charge multiple UAVs in turn), which are compatible with the low-voltage power demand in agricultural scenarios.

Summary

The core advantages of the battery lie in low-voltage adaptability + large-capacity energy storage + high safety. Therefore, it mainly focuses on low-voltage power equipment (low-speed vehicles) and small and medium-power energy storage scenarios (residential, small commercial and industrial, backup power sources), especially in scenarios with high requirements for battery life and safety, it is more competitive.

Working Principle

The working principle of lithium iron phosphate batteries is based on the intercalation and deintercalation of lithium ions between the positive and negative electrodes. During charging, lithium ions are deintercalated from the positive electrode material (lithium iron phosphate), migrate through the electrolyte to the negative electrode, and intercalate into the negative electrode material. The discharge process is the reverse: lithium ions are deintercalated from the negative electrode, return to the positive electrode through the electrolyte, and release electrical energy.

Product Features

• High Safety: Lithium iron phosphate materials have excellent thermal stability and are less prone to thermal runaway or other safety accidents under normal operating conditions. Additionally, the battery is usually equipped with an advanced BMS (Battery Management System), which provides multiple protection functions such as overcharge, over-discharge, short circuit, and overheating protection.
• Long Service Life: It has an extended cycle life of over several thousand times. Taking 80% depth of charge-discharge cycles as an example, it can effectively reduce long-term usage costs, basically matching the lifespan of the entire vehicle. It is maintenance-free for life, reducing the frequency and cost of battery replacement.
• High Charge-Discharge Efficiency: With a charge-discharge efficiency of over 95%, it supports fast charging and discharging, which can effectively improve energy utilization and better meet the power demands of equipment.
• Strong Environmental Adaptability: It operates within a wide temperature range, typically from -20ºC to 60ºC, enabling stable performance in various complex outdoor environments, whether in cold northern regions or hot southern areas.
• Good Environmental Friendliness: Lithium iron phosphate batteries do not contain heavy metals such as lead, mercury, or cadmium, making them environmentally friendly. They cause minimal pollution to the environment during production, usage, and disposal.
