Briefly introduce what is power battery | FUNSONG

A power battery is an energy storage device that is mainly used to store electrical energy to provide power to electric vehicles or hybrid vehicles. The power battery stores electrical energy in chemical substances. When the vehicle needs power, the battery releases the stored energy to drive the electric motor to make the vehicle run.
A power battery is usually composed of multiple battery cells, and each battery cell is a chemical reaction system. These cells can be connected together in series or in parallel to provide the required voltage and current. The chemical reaction in the battery cells converts electrical energy into chemical energy and reverses it back to electrical energy when needed to provide the desired power. The performance and life of a traction battery depends on many factors, such as the chemical composition of the battery, the design of the battery, temperature, and usage.
Because EVs and HEVs require traction batteries to provide drive energy, traction batteries play a vital role in these vehicles. With the increasing popularity of electric vehicles and hybrid vehicles, the demand for power batteries is also increasing.

Power Batteries for Grid Stabilization: Power batteries are increasingly utilized in grid stabilization systems to address fluctuations in electricity demand and supply. These batteries provide fast-response power injections during peak demand periods and absorb excess power during low demand periods, helping maintain a stable and balanced grid.

Power Batteries for Uninterrupted Power Supply (UPS):Uninterrupted power supply (UPS) systems require dependable energy storage solutions, and power batteries fit the bill perfectly. These batteries offer high power output and long runtime, providing critical backup power for data centers, medical facilities, and other mission-critical applications, ensuring continuous operations.

Traction battery is a type of battery specially used in electric vehicles and other applications requiring high power and long-life power supply, with the following characteristics:
High energy density: The power battery can provide a large amount of electric energy with a small volume and weight, which is one of the key factors to ensure the mileage of electric vehicles.
High power density: The power battery can provide a large amount of current output in a short time to meet the high power requirements of electric vehicles such as rapid acceleration and climbing.
Long life: The power battery has a long life and can withstand a large number of charge and discharge cycles, so it can provide stable and reliable power output for electric vehicles and reduce battery replacement costs.
Fast charging: The charging speed of the power battery is fast, and the battery can be fully charged in a short period of time, which is an important factor to improve the efficiency and user experience of electric vehicles.
Low self-discharge rate: The self-discharge rate of the power battery is relatively low, and the battery can maintain a high charge state even if it is not used for a long time.
High stability: The power battery has high safety and stability, and can maintain good battery performance under different working temperatures and environmental conditions.
In general, a power battery is a high-performance battery technology with features such as high energy density, high power density, long life, fast charging, low self-discharge rate, and high stability, and is ideal for electric vehicles and other high-power applications. Provides a reliable source of power.
