Serious Car Accident in China Highlights the Advantages of BYD's Blade Battery

JAKARTA - The BYD Qin L plug-in hybrid sedan has been in the spotlight after a viral accident video showed the durability of the vehicle's structure when it suffered a serious collision. According to a Chinese media report, TT, the car suffered heavy damage to the front after colliding with a gasoline-powered sedan in a collision at an angle of about 45 degrees.

Despite experiencing significant deformation, the vehicle safety system managed to prevent a fire in the battery, while the opponent's car was on fire shortly after the incident. The lithium iron phosphate (LFP) based Blade battery pack integrated in the vehicle is reported to remain intact without showing any symptoms of thermal runaway.

Immediately after the collision occurred, the vehicle sensor immediately activated the high voltage disconnection system automatically. There were no casualties or injuries in the accident because all passengers managed to get out of the vehicle before emergency personnel arrived at the location.

Launching from Carnewschina, Monday, June 22, indicates that the accident occurred in the Dalian City area, Liaoning Province, China. A search for the location showed the presence of the Jinghua car wash facility around the area of the incident.

A number of elements such as utility poles on the road, traffic light configurations, and rows of coniferous trees on the side of the road also strengthen the suspicion that the incident took place in the northern urban area of China.

Meanwhile, the vehicle that was burned was a third generation Mazda 3 Axela compact sedan produced in the period 2014 to 2019. Identification was carried out through the shape of the door, the design of the wheel arches, and the silhouette of the side glass which can still be recognized even though the vehicle has suffered quite severe heat damage.

The 45-degree collision is believed to channel the energy of the collision into the front crumple zone and cause damage to the Mazda fuel system. The high-voltage isolation system on the BYD Qin L plays an important role in preventing electrical sparks from occurring in the damaged plug-in hybrid powertrain components.

The process of breaking the current lasts only a few milliseconds after the collision is detected. In addition, the Blade LFP battery cell uses materials known to have high stability and can withstand oxygen release when subjected to physical deformation.

The protective layer keeps the battery pack installed on the floor of the vehicle safe during the accident. The collision concentrated in the front wheel area also triggers the activation of two airbags automatically and locks the transmission position instantly.

This post-collision safety protocol is designed to keep the vehicle stationary and prevent the vehicle from moving accidentally when there is a risk of fire around the location. At the same time, the internal safety system permanently disconnects the electrical line to provide additional protection for the cabin and passenger space.

Safety against fire risk is still one of the aspects that receives great attention in the Chinese automotive industry, especially in electrified vehicles. Various industry discussions often compare the durability of vehicles in real accident conditions with other external threats.

This includes fires originating from the surrounding environment. Incidents such as spontaneous fires in vehicles in the middle of traffic serve as a reminder that manufacturers continue to develop insulation and protection technologies that can work automatically when a collision occurs.
