Battery Charge and discharge of electric bike

Battery Charge and discharge of electric bike

1. The principle of battery charging and discharging


The principle of charging and discharging electric bicycle batteries is actually very simple:

1. The process of charging the battery of an electric bicycle: by inputting electrical energy, the lead in the battery fluid is reduced to metallic lead to store electrical energy.

2. The discharge process of the electric bicycle battery: the chemical reaction between metallic lead and electrolyte becomes ionic lead while releasing electric energy.


 

2. Precautions for charging electric bicycles

1. Never plug the battery of an electric bicycle into the charger for a long time. Even if it is fully charged, the charger will not stop charging the battery.


2. When charging, the battery is hot, leaking, and the battery swells and deforms. At this time, the battery has been overcharged. 75% of the battery damage is due to this reason, everyone should pay attention to it.


3. When the charger is working, the temperature is relatively high. After long-term use, the internal electronic component parameters will drift, resulting in a change in the output voltage charging suspension voltage. At this time, the charger warning light is inaccurate.


4. Charge it without going out and come back, so it’s easy to overcharge. The battery life is calculated based on the number of recharges. Even if the battery is not used up, it will count as one recharge, unless you ride more than 30 kilometers a day.


5. Estimate the remaining power of your battery according to the digital odometer on the car (this time reflects the importance of the odometer). For example, a 12AH battery runs 40 kilometers with full power, and the car has run 30 kilometers. The battery consumption is 12*30/40=9AH. If the charging current of the 12*30/40=9AH charger is 1A, theoretically it takes 9 hours to charge, considering the charging current at the end of the charge. Decrease, the maximum charging time cannot exceed 11 hours.


A few things to note

First of all, it is recommended to read the instructions and charging precautions carefully before charging. This will greatly help you how to use the electric car correctly.

Confirm that the output voltage of the charger matches the battery and the polarity is the same.

Charging should be done in a ventilated place indoors. If it is exposed to direct sunlight, it is best to cover it upside down and not charge upside down.


What is the general service life of electric vehicle batteries?
 

For users whose daily traffic distance is less than 30 kilometers, if the motor, controller, charger and other factors are good, and the method of use is not improper, the minimum service time of a group of better electric bicycle batteries should reach more than 1 year. It can be guaranteed.


If the maintenance is a little careful, it can usually take 1 and a half to 2 years; if you add a maintainable technical solution, the time can be extended through professional maintenance, and even a battery life of a set of electric vehicles can reach 3 years. possible.
