The safety of the smart battery swap cabinet: what is the truth?

Today, with the increasing popularity of electric bicycles, the safety of charging has become the focus of social attention. In 2021, there were more than 14,000 fires caused by faulty electric bicycles and their batteries, killing 41 people and injuring 157 people.

On February 23, 2023, a fire broke out in the parking shed of an enterprise in Zhenjiang, Jiangsu.

On December 12, 2022, an electric bicycle charging shed in a community in Shenzhen, Guangdong Province caught fire late at night.

The list goes on and on.

A fire broke out in a small area of Tongzhou District, Beijing, due to the charging explosion of lithium batteries for electric bicycles, resulting in 5 deaths.

A fire broke out in a resident's home in Lishuiqiao, Chaoyang District, Beijing, due to a faulty electrical wiring during the charging process, although there were no casualties, but the lesson was profound.

Looking back on the electric bicycle fire accidents in recent years, it is not difficult to find that many tragedies stem from non-standard charging behaviors or safety hazards of charging piles.

A battery swap cabinet in Jinshan District caught fire

Compared with the frequent fire accidents of charging piles, the intelligent battery swapping cabinet has obvious advantages in safety. An electric bicycle battery swap cabinet in Jinshan District burst into flames, although the fire broke out, but the sprinkler system in the battery swap cabinet responded immediately, and the fire was quickly controlled, causing no casualties. It fully demonstrates the rapid response ability and effective fire control measures of the intelligent battery swapping cabinet in response to emergencies.

The intelligent battery swapping cabinet has built-in multiple safety protection devices, such as temperature sensing, smoke detection, automatic fire extinguishing, etc., which can quickly take measures to avoid fire when the battery is abnormal. Even if a fire has already broken out, the internal fire protection system can be activated quickly to minimize the fire and ensure the safety of users and the surrounding environment.

Traditional charging piles have certain limitations in terms of safety. Because charging piles are usually installed outdoors or in public areas, it is difficult to achieve all-weather monitoring and maintenance, coupled with the lack of safety awareness of some users, random charging, private pulling of wires and other behaviors occur from time to time, which greatly increases the risk of fire.

In order to crack the illegal parking and charging of electric bicycles, since the beginning of this year, many streets have carried out pilot battery swapping cabinets.

"Since April this year, 20 battery swap cabinets and 200 battery bins have been completed, covering more than 800 person-times at most...... said the director of the Fengpu Street Community Management Office. According to statistics: since the beginning of this year, the number of 110 police reports and 12345 hotline reports caused by illegal parking and charging of electric bicycles in the area has decreased by 65% year-on-year, and the number of electric bicycle fire alarms has "zero".

The intelligent battery swapping cabinet has shown significant advantages in terms of safety. Through centralized management, unified battery swapping and built-in multiple safety protection devices, the risk of electric bicycle fire is effectively reduced, and the safety of users and the surrounding environment is guaranteed. With the continuous progress of technology and the continuous guidance of policies, the battery swap mode is expected to become the mainstream trend of electric vehicle energy replenishment in the future.
