48V Storage Battery Advantage
Compared to other types of batteries, 48V storage battery have unique voltage specifications and exhibit multiple advantages in many application scenarios, mainly reflected in the following points:
1.Energy and power density advantages
48V energy storage battery can provide higher voltage with the same battery volume and weight, which means it can output greater power. For example, in the field of electric tools and electric transportation, 48V batteries can provide electric bicycles, electric motorcycles, electric tricycles, etc. with stronger power performance, faster acceleration, and stronger climbing ability. Compared with some low-voltage batteries (such as 12V, 24V), 48V batteries have more advantages in power output and can meet the needs of high-power devices. At the same time, with the development of technology, the energy density of some 48V energy storage batteries is constantly increasing, which can store more electricity in the same space, thereby extending the range of the device. For example, in electric bicycles, 48V batteries can provide longer driving range than traditional low-voltage batteries.
2.System efficiency advantage
In some application scenarios, the voltage level of 48V is relatively high. According to the power formula (power equals voltage multiplied by current), under a constant power, the higher the voltage, the smaller the current. The smaller the current, the lower the line loss generated during transmission, thereby improving the overall efficiency of the system. For example, in communication base stations, when 48V energy storage batteries supply power to devices, compared to low-voltage battery systems, the line loss is smaller, which can more effectively transfer the energy of the battery to the device end and reduce energy waste. In addition, higher voltage can also reduce the number of batteries connected in series, reduce energy loss caused by differences in battery consistency in the series battery pack, and further improve system efficiency.
3.Security advantage
A voltage of 48V belongs to the safe voltage range (generally believed to be relatively safe for the human body below 50V), and compared to some high-voltage battery systems (such as the common several hundred volt battery system in electric vehicles), the potential danger to the human body during use is relatively small. In applications such as home energy storage and power tools, users may come into direct contact with batteries or related devices. The 48V voltage reduces the risk of electric shock and improves safety during use. At the same time, the 48V energy storage battery system is relatively simple in design and protection measures, and does not require complex insulation and protection measures like high-voltage battery systems, reducing the cost and complexity of the system.
4.Cost and maintenance advantages
The structure of a 48V energy storage battery system is relatively simple and does not require complex battery management systems (BMS) and electrical equipment like high-voltage battery systems. This makes the cost of the 48V energy storage battery system relatively low, providing a certain price advantage in both the manufacturing of the battery itself and the procurement of supporting equipment. In terms of maintenance, due to the simple system structure and relatively few fault points, the difficulty and cost of maintenance are also relatively low. For example, in electric bicycles and power tools, the maintenance of 48V batteries is relatively easy, and users can easily replace and troubleshoot the batteries, reducing usage and maintenance costs.
5.Advantages of compatibility and application flexibility
48V is a relatively moderate voltage level that has wide applications and mature technical support in many fields. In household energy systems, 48V energy storage batteries can be easily connected to common household appliances such as low-power lighting equipment, small appliances, etc., without the need for complex voltage conversion devices,In addition, 48V energy storage batteries can be flexibly combined and configured according to actual needs to meet different power and capacity application scenarios. For example, in data center backup power systems, multiple 48V battery packs can be connected in parallel to increase the system’s capacity and power.
