We know that even when new energy vehicles are parked with the brakes engaged and not in use, they still release a certain amount of electricity because both the storage battery and high-voltage battery will self-discharge. This phenomenon of self-discharge is a normal physical process and does not require concern.
The extent of battery discharge is also closely related to external environmental conditions. If the external environment is cold, the battery pack will discharge more frequently on its own. This is because at low temperatures, the lithium ions in the lithium battery decrease, leading to a decrease in the net discharge rate of the battery. Therefore, it is normal for new energy vehicles to experience discharge overnight on cold nights.
Although it is normal for new energy vehicles to lose charge overnight, excessive discharge should be taken seriously. This may indicate a problem with the battery, and the vehicle should be promptly taken to a professional institution for inspection to ensure its normal operation.
The occurrence of discharge overnight in new energy vehicles is a normal situation. It is caused by battery self-discharge and the influence of external environmental conditions. Only when there is excessive discharge should the possibility of a battery problem be considered. Therefore, for owners of new energy vehicles, understanding the reasons and frequency of discharge is key to maintaining a good driving experience.
