How much power will the electric car consume when it is not riding?
In the process of daily use of electric vehicles, many car owners have experienced the experience of "why does electric vehicles still consume electricity when they are not used?" "How much power will it consume if it is placed for a long time?" Now Changxin answers your questions and dispels your doubts.
In fact, the above problems are the result of battery self discharge. Self discharge is a normal phenomenon of all electric vehicle batteries. Usually, the battery will automatically discharge 1% to 2% of the power every day. Once the time is too long, all points in the battery will be discharged automatically. This is also the case that the power of electric vehicles is only half in a month on weekdays. So the problem is, what are the reasons for the self discharge of electric vehicle batteries? What are the practical solutions? There are four main reasons for the self discharge of electric vehicle batteries:
1、 There is a potential difference between the upper and lower parts of the electrode plate At present, the battery will sink after being stored for a period of time, which will lead to the loss of battery potential in most electric vehicles. Solution: daily use, more charging can be avoided.
2、 Electrolyte overflow, positive and negative path During daily driving, when the road conditions are bumpy and the battery is aged, the battery will overflow electrolyte, resulting in a path between the positive and negative poles, resulting in self discharge of the battery. Solution: take less bumpy roads in daily use and strengthen the maintenance of the battery.
3、 The battery is of poor quality and there are too many impurities in the electrolyte When changing batteries, a small number of car owners will choose some low-cost and low-quality batteries. Although there will not be much difference in the initial stage, with the passage of time, due to the poor quality of the battery and too many impurities in the electrolyte, the self discharge speed of the battery will accelerate, resulting in the loss of electricity. Solution: try to choose brand batteries and don't be greedy for small and cheap.
4、 Falling off and short circuit of active material of electrode plate During the use of electric vehicles, many users like to use high current charging, which will lead to poor adhesion of active substances on the electrode plate and even fall off, resulting in short circuit of the electrode plate and accelerating the self discharge of the battery. Solution: try to make the charger special for the car, and avoid using high current charging.
Finally, Changxin reminded the majority of car owners that if the electric vehicle is idle for a long time, the electric vehicle should be fully charged and placed in a cool and dry place.
In addition, special attention should be paid to charging electric vehicles every 3-5 days, and avoid long-term power loss. In addition, it is necessary to disconnect the main switch of the battery or unplug the battery plug during storage, because in addition to the self discharge of the battery, the placement of accessories such as the controller will also lose power.
If you really don't have time, you can entrust your family or friends to help you charge regularly, so that you can protect the battery to the greatest extent and prolong its service life on the premise of long-term storage.
