The working principle of the accumulator

An accumulator is a device that can store energy and release it when needed. It has extensive applications in many fields, including industry, automobiles, power systems, and so on. The principle of energy accumulators can basically be summarized into two main types: mechanical energy accumulators and electrochemical energy accumulators.

  1. Principle of mechanical energy accumulator:

Spring accumulator:

Spring accumulators use the deformation of springs to store and release energy. The principle includes the following steps:

Energy storage stage: When external forces are applied to the spring, the spring undergoes deformation, storing energy during the deformation process.

Energy storage: The energy stored by springs can be released by releasing external forces when needed.

Gas accumulator:

Gas accumulators use the compression and expansion of gas to store and release energy. The principle includes the following steps:

Energy storage stage: In the energy storage stage, external forces are used to compress gas into the accumulator.

Energy storage: The stored energy can be released when needed by allowing the gas to expand.

  1. Principle of electrochemical energy storage:

Battery:

A battery is an electrochemical energy storage device that uses chemical reactions to store energy into electrical energy. The principle includes the following steps:

Energy storage stage: In the energy storage stage, the chemicals in the battery react and convert electrical energy into chemical energy.

Energy storage: The stored energy can be released when needed by converting chemical energy into electrical energy.

Supercapacitors:

Supercapacitors (or supercapacitors) are also a type of electrochemical energy storage device, but unlike batteries, they mainly rely on the separation of charges. The principle includes the following steps:

Energy storage stage: In the energy storage stage, charges are separated and stored in the electric field between the electrodes.

Energy storage: The stored charges can be released by connecting circuits when needed.

The selection of energy accumulators depends on the specific application requirements, such as energy storage capacity, charging and discharging speed, lifespan, etc. Different types of accumulators have unique advantages and limitations in different fields and applications.
