Is it reasonable for the residential property management to prohibit the charging of lead-acid batteries of electric vehicles upstairs?

Residential property does not allow electric vehicle batteries to be taken upstairs for charging, which seems unreasonable but reasonable. After all, there are certain safety hazards in the charging process of electric vehicle batteries, so such batteries are not suitable for charging in indoor environment. Because the fire of electric vehicle charging is mainly due to the internal damage of the battery during long-term use or its own quality problems. Therefore, whether the battery poses a risk has nothing to do with its location. The risk probability of outdoor charging and indoor charging is the same.

The reason why the residential property requires electric vehicles to be charged outdoors is also just in case. If the electric car is charged outdoors, even if it catches fire, the loss may be the car itself or other nearby vehicles, which may not necessarily cause harm to people. However, if the battery is charged indoors, once it catches fire and spontaneously ignites during the charging process, it may ignite the flammable items indoors, causing the house to catch fire and eventually causing casualties. In addition, even if the battery of the electric car is removed for charging, the risk of charging indoors is definitely higher than that of charging outdoors. Because the outdoor air is more ventilated, it is beneficial to the heat dissipation of the battery during charging, and it can avoid the short circuit and fire of the battery due to heat accumulation. At the same time, the charging points of outdoor electric vehicles are all planned by the property, so there won't be too many combustible materials around, and the property security guards will patrol and put out the fire in time. When charging indoors, it is difficult to ensure that people are always watching, and there are often a lot of combustible materials indoors. Once the battery catches fire during charging, it is easy to cause serious consequences.

Moreover, although the battery of the electric vehicle can be taken down for charging, during the long-term handling and charging process, the internal circuit of the battery may be damaged and short-circuited due to bumping and other factors, and the battery energy of the electric vehicle is high, so it is difficult to put out a fire once it occurs. Therefore, for residential properties, the consequences and responsibilities of charging electric vehicle batteries indoors and outdoors are completely different. Once a fire breaks out in a residential building, in addition to the residents who caused the fire, the residential property should also bear part of the responsibility. Moreover, the public security fire department has long banned electric vehicles from charging indoors. Although the regulations do not prohibit taking the batteries of electric vehicles home for charging, if there is a fire hazard, the charged households and residential properties will be punished.

Therefore, in order to avoid risks, it is understandable that residents are forbidden to take the lead-acid batteries of electric vehicles upstairs for charging. As the owner of electric vehicles, they should park electric vehicles reasonably and charge them outdoors according to regulations.
