Super capacitors make it easier for diesel vehicles to start at low temperatures

When the temperature reaches below minus 10 degrees, the high-current output performance of the vehicle battery is greatly reduced, resulting in the inability to drive the diesel engine to start. As a high-performance energy storage device, supercapacitors can effectively maintain high-current output performance at low temperatures, and the low-temperature startup advantage is very obvious.

Vehicles driven by kam diesel engines, without exception, are powered by a dedicated lead-acid battery to drive the starter motor, thereby driving the diesel engine to compression ignition. During the starting process, the input current power required at the moment of starting the motor is very large. The best working temperature of the commonly used lead-acid batteries is 10°C～40°C. Under low-temperature conditions, the viscosity of the electrolyte increases. The penetration capacity of the plate decreases and the internal resistance increases, which leads to a significant decrease in the terminal voltage and capacity of the battery and a decrease in output power when starting, and the inability to support the starter to drive the diesel engine to reach the minimum starting speed makes it difficult to start the vehicle.
