The production of batteries that are easier to carry, install, and easier to use than heavy products is increasing day by day, and many products made with batteries are currently being produced and sold in vehicle electric products. In the past, vehicles were often used without installing additional accessories when purchasing vehicles, but recently, additional accessories that use black box auxiliary batteries are often installed in vehicles. In particular, when a vehicle black box is installed and used as a constant power source among accessory devices, the voltage of the vehicle battery drops after parking for a long time, so the vehicle often does not start. For this reason, the number of vehicle drivers who install auxiliary batteries for vehicles is increasing to prevent a voltage drop of batteries installed in vehicles. However, it was confirmed through a press release from related agencies that some of the commercially available black box auxiliary batteries were arbitrarily changed and sold by major components such as cells inside the batteries unlike the time of certification. As the use of auxiliary batteries for vehicles increases, a number of related fires often occur, causing the vehicle to burn down or repair costs excessively. The research team of Changwon Fire Department analyzed the recent fire cases and visited related companies and related institutions and conducted a re-experiment in an environment similar to the fire conditions to investigate the risk of lithium-ion batteries charging/discharging at low temperatures.
