What is the difference between a traction battery and a startup battery
Aug 05, 2018

Many friends do not know much about batteries in life. Recently, we have also seen the statement about traction batteries and battery starting. I understand that the traction battery has a larger relative resistance, but it has a better stability and a stronger ability to continue the current. . However, what is the difference between traction battery and starting battery? The following little editor to introduce to you:

In the charge of charging: the traction battery is charged with a special charger, usually after the end of the work. General battery discharge 20%--100% is charged. The starting battery is charged at the mechanical work (and stable).

In terms of discharge: traction battery is suitable for continuous discharge for a long time. It allows a certain degree of deep discharge. Usually, the manufacturer recommends not to discharge more than 80%, but in practice, it is found that the effect of 100% deep discharge on the performance and life of the battery is far less than the influence of other types of batteries. The starting battery can not be used for deep discharge. Generally, the discharge is more than 20%. The starting battery is suitable for a short time and large current discharge. For example, when starting a vehicle in winter, it is sometimes required to release more than 500A of current in three seconds. (for 100AH batteries)

In manufacturing, traction batteries usually use tubular plates on positive plates, and positive plates on starting batteries are pasted plates. The electrode plate of the traction battery is thick, and the plate of the starting battery is thin.

The starting battery can not replace the traction battery.

An electric car battery is a lead-acid cotton lotus root battery. Its discharge is lasting, but the discharge is not high at the moment. Its electrolyte is not 1.28 of the sulfuric acid, but the chemical liquid and the plate produce the voltage and current. The separator has the effect of water absorption. The electrolyte is not easy to dry up and the electrolyte needs no frequent inspection. Electricity can reach hundreds of amperes. Its electrolyte is 1.28 sulfuric acid and polar plate to generate voltage and current. The level of the car battery is 10-15 millimeters higher than the plate. If it is lower than the plate, it will seriously damage the battery. Check the liquid level of the electrolyte often. If you use a car battery instead of a battery, you need a car, 20AH. The replacement of battery 60AH can achieve the discharge time of electric vehicles.

Through the introduction above, I believe you have some understanding of the difference between traction batteries and startup batteries, I hope the above can help you.
