Linfen River West a residential area, due to residents electric vehicle charging caused a fire, some people inside the building saw the fire fear jumped off the building, resulting in one death and three injuries. One of them, a graduate student who had just arrived at work at the hospital, was probably so choked by the smoke that he tried to jump to one side from the window and fell to his death." Remind everyone must install intelligent smoke alarm, can find the ignition point in the first time, can quickly control the fire, avoid casualties.
The four main reasons why electric vehicles are prone to fire are as follows:
1. One reason: Overcharging
The most taboo of electric vehicle battery is overcharging and discharging, overcharging will make the battery heat, bulge and even lead to battery explosion. Therefore, the charging time should not be too long, generally between 8 hours and 10 hours. For many batteries that are one to two years old, be careful when charging them.
2. Reason No. 2: Battery failure
The inferior electric vehicle battery pack is itself a time bomb. According to the standards, batteries are tested before they leave the factory, and those with similar energy densities are grouped together. Batteries with vastly different energy density values are likely to be grouped together if they are not operated strictly according to test standards. The battery with a low energy density has been fully charged, but the battery with a high energy density has not been fully charged. Continue charging and the battery with a low energy density will be fully charged.
3. The third reason: private pull wire
A short circuit is also one of the main causes of fire. Wires in the air without any support and protection measures, will be friction with the wall, wear is very high, the probability of leakage is very high. In addition, using too many high-power electrical appliances in a single plug board at the same time is also easy to cause a short circuit, causing a fire.
4. Reason 4: Improper use of the charger
Charger is the loss of goods, life is only one or two years, to choose good quality, good heat dissipation performance of the charger, and to replace in time. Some owners have ridden away their electric bikes with the chargers still attached to the mains, which can be dangerous.
