1、What is the working principle of the battery of electric bicycle?
Battery use process battery discharge process, battery discharge on the negative electrode oxidation reaction, supply electrons to the outside, on the positive electrode reduction reaction, accept electrons from the external circuit, current flow from the positive electrode to the negative electrode through the external circuit, electrolyte is an ion conductor, ions in the battery internal directional movement between the positive and negative electrode and conductive, cation flow to the positive electrode, anion flow to the negative electrode.
The negative electrode of the battery discharge is the anode, and the positive electrode of the discharge is the cathode. An oxidation reaction occurs at the interface between the two types of conductors at the anode, and a reduction reaction occurs at the interface between the two types of conductors at the cathode. The whole battery forms a complete discharge system consisting of the electron system of the external circuit and the ion system of the electrolyte solution, thus appearing to supply electricity.
2、What kinds of storage batteries are commonly used in electric vehicles?
Lead-acid battery and lithium-ion battery.
Among them, lead-acid batteries are the cheapest, but they are large, heavy and short-lived.
Lithium-ion batteries can also be divided into two types, the single voltage is 3.7V each 3.2V, of which the 3.2V polymer battery is said to be safer than the other.
The disadvantage of lithium-ion batteries is expensive, but light weight, small size, long life (as far as I understand, lead-acid batteries daily use after the restorer, life should not be less than lithium).
3, lead-acid battery charging process of electrochemical reaction?
When the lead-acid battery is discharged, the electrons on the negative plate enter the positive plate via the load to form a current under the potential difference usage of the battery, while the chemical reaction takes place inside the battery.
4、Can I use the electric car charger casually?
Electric car charger can not be used casually, there are two important reasons.
1、Electric car chargers are specially matched with electric cars.
2, the electric car charger is not the same size model, one is a fast charge, one is a slow charge, both will damage the battery, reduce the life of the battery use.
5, how to maintain the electric bike battery?
Remember to charge after use, but also watch the point not to overcharge for too long, so that the battery is easy to bulge, in addition, try not to use a little electricity is not so will damage the battery life, and do not use for a long time, so the battery shelved for a long time, the chemical properties will not be so lively will also shorten the life.
6、Why is the connection wire of electric car battery box always hot?
If the electric car can drive normally, you can exclude the short circuit caused by the heat. It may be that the connection wire is too thin because the current is very high when the electric car is running, and the wire will be too thin if it gets hot. The solution is to replace a 2.5 square wire may be able to solve the problem of heat!
7、What is the effect of ambient temperature on battery performance?
Among all the environmental factors, temperature has the greatest impact on the charge/discharge performance of the battery. The electrochemical reaction at the electrode/electrolyte interface is related to the ambient temperature, and the electrode/electrolyte interface is regarded as the heart of the battery. If the temperature drops, the reaction rate of the electrode also drops.
Special reminder: When it is cold, it is best to prevent putting the electric car outdoors for charging. In addition, when the indicator light shows low battery during the ride, it is best to turn off the power immediately, if you continue to forcefully accelerate, the car controller will be damaged. All in all, whether it is daily riding or temporarily not, we should pay attention to the maintenance of electric car battery, only take good care of the battery, in order to effectively extend the service life of electric cars.
