Cans are sealed enclosures inside the battery, in which the main working elements are located: plates and electrolyte. They create the necessary environment for chemical reactions in which the battery stores and outputs energy.
In fact, one can is one battery. Inside each case there are all the necessary components for converting chemical energy into electrical energy. In more powerful Edcon battery models, the assembly consists of several such cans connected to each other to achieve the desired characteristics.
Material properties and housing
The jars are made of plastic (polypropylene) to withstand mechanical stress and exposure to chemical substances. Polypropylene was chosen due to its high resistance to chemicals, high temperatures and mechanical influences. It ensures tightness, protecting the internal components from damage and leakage of electrolyte, as well as resistant to moisture and corrosion. This plastic is lightweight and very durable, which significantly increases battery life and increases its safety.
Chemical processes and energy transfer
Complex chemical reactions take place inside each Edcon battery jar, which ensure the storage and release of energy. The main components are lead plates and an electrolyte, usually a solution of sulfuric acid. During charging and discharging, these components interact to create electrode reactions.
When the battery is discharged, the lead plates turn into diphosphoric acid, and when charged, they turn into lead and lead dioxide. It is these transformations that cause the release and absorption of electrons, forming an electric current. As a result of this ion exchange, energy is transferred inside the electrolyte, which is used to power the devices.
The processes inside the jar are associated with a constant change in the composition of the plates and electrolyte. Over time, with prolonged use, such reactions can lead to precipitation, gas accumulation, or corrosion, which impairs efficiency and increases component wear.
Connection methods within the module
In Edcon batteries, the cans are arranged in a row inside the case, forming a module, and then connected to each other. Typically, a serial connection of cans is used: the positive terminal of one can is connected to the negative terminal of the next. This method increases interbank tension, not capacity. For example, one bank provides 2 V and 10 Ah; six connected in series provide 12 V and 10 Ah.
The parallel connection increases the capacity, but the voltage remains equal to one jar. In car batteries, it is the serial connection that is used to achieve the desired operating voltage (for example, 12 V).
Consequences of bank failure
If the bank inside the Edcon battery fails, it can have serious consequences for the operation of the entire battery. A damaged jar will no longer be able to properly participate in the process of storing and releasing energy. As a result, the battery will lose some of its capacity, start to discharge faster, or work unevenly. An electrolyte leak may occur, which is dangerous to the environment and increases the risk of damage to other battery cells. In the worst case, a damaged jar can cause an internal short circuit, which will lead to heating, failure of the entire device, or even a fire. Therefore, it is important to detect and repair such damage in a timely manner in order to avoid more serious problems and extend battery life.
Causes of damage and wear
The reasons for the bank’s failure may be different factors. The most common are mechanical damages: impacts, falls, vibrations that can crack or deform the body. It is also caused by prolonged exposure to high temperatures or severe over-discharge, accelerating wear and developing chemical processes inside, damaging the plates and electrolyte. Damage caused by electrolyte leaks or poor sealing can also lead to the destruction of the jar. Careless handling, improper operation, or the use of substandard materials all increase the risk of battery failure and deterioration.
Summary
Cans are the most important components of Edcon batteries. They create a sealed environment for chemical reactions, ensure durability and safety, and also allow you to increase the capacity and power of the battery. In fact, one can is a mini battery. Proper connection and care of them is the key to long and reliable operation of your Edcon battery.
