What's the difference between a car battery and an electric car battery?

The difference between internal structure and type:

When the automobile battery is used for starting, it must provide a large current in a short time without long-term power supply, so the plates are thin and many, while the electric vehicle battery needs long-term deep discharge, so the plates are thick.

Other differences:

There are also some small differences, such as appearance size, connection mode, dry load, wet load and hourly charging rate.

Extended data:

Electric vehicle battery:

The battery of electric vehicle is the power source of electric vehicle. Most electric vehicles are equipped with lead-acid batteries, which have low cost and high cost performance. Because this kind of battery can be used repeatedly, it is called "lead-acid battery".

Type:

There are four kinds of power batteries that can be used for electric bicycles, namely valve-regulated lead-acid maintenance-free batteries, colloidal lead-acid batteries, nickel-hydrogen batteries and lithium-ion batteries.

Automobile battery:

Battery is an indispensable part of automobile, which can be divided into traditional lead-acid battery and maintenance-free battery.

Because lead-calcium alloy is used as the grid frame of storage battery, the amount of water decomposition and evaporation during charging are low. In addition, the shell adopts a sealed structure, and little sulfuric acid gas is released. Therefore, compared with the traditional battery, it has the advantages of no need to add any liquid and long storage time of the wiring pile.
