Yes.
In fact, electric vehicles generally suffer from self-discharge. Even if a small battery is not used, it self-discharges 1-2% of its power in a day. This is also one of the main reasons why many people leave their electric vehicles at home and lose power. Of course, this is just normal battery self-discharge. If external factors cause self-discharge, it will seriously affect the battery life.
When the battery wires form a bridge with some external bodies, a relatively strong discharge phenomenon is likely to occur, or iron wires, copper wires, etc. will be discharged. are accidentally placed on the battery, damaging The connections of the positive and negative electrodes can also cause discharge.
The electrolytes contained in electric vehicle batteriesics produced by usual manufacturers are very pure and contain almost no impurities, so the discharge is very slow and within the normal range. Some electric vehicle batteries discharge very quickly. The main reason is that the electrolyte is impure and contains impurities, which creates a certain potential difference, causing the battery to short circuit and consume power.
