Types and features of traction batteries
Traction batteries are not a specific type of battery. Rather, it is a group of power supplies by purpose, which includes lead acid, lithium and alkaline batteries. Traction batteries in most cases are used to provide power to the electric motor in various vehicles, equipment, devices and mechanisms. A complete overview of traction batteries can be found at https://akbinfo.ru/vybor /tjagovye-akkumuljatory.html , and in this article we will tell you the basic data about them.
What's special
The main difference between traction batteries and starter batteries familiar to motorists is a different mode of operation. The car battery only releases its charge for a few seconds when the starter motor cranks the engine. After that, it is charged from the generator. The traction batteries release their charge as long as the electric motor is running. After that, they are set to charge. All their work takes place in charge and discharge cycles.
Hence the main requirement for this type of battery. They must be resistant to deep discharge, and generally to work in the "deep cycling" mode. During operation, they are regularly discharged to 80% of the nominal. At the same time, they must provide the required discharge current even under conditions of strong discharge. As you can imagine, starter batteries cannot be used as traction batteries.
Varieties
As mentioned, there are three main types of batteries included in this group.
- Lead Acid.
- Lithium.
- Alkaline.
There are also a number of rare and exotic batteries, many of which are currently in development status.
Lead Acid
There are variations here: WET, AGM, GEL. Lead-acid WETs with liquid electrolyte can act as starters, but there are also traction options. For example, these are models with armored electrodes (PzS, PzB, PzV). These enhanced modifications can carry continuous deep charges and subsequent discharges.
AGM and GEL may well be used as traction. In this capacity, they are used on motor boats, electric scooters, snowmobiles, jet skis. They can successfully play the role of both starter and traction.
Alkaline
Alkaline batteries are most often used as traction batteries. There are two main varieties, depending on the electrodes used: nickel-cadmium and nickel-metal hydride. They easily tolerate deep discharge and continuous cycle operation�
