Lamborghini Uses Supercapacitors As Power To Develop A New Super Run
Aug 20, 2018

Supercapacitor is a new type of energy storage device. It has the characteristics of short charging time, long service life, higher tolerance to high temperature and low temperature than battery, energy saving and environmental protection.

In the view of Zhong Dianbo, chief engineer of CRRC Super Capacitor and chief technical engineer of CRRC, there is no problem in using supercapacitors in sports cars, but they must be used together with conventional batteries and cannot be used alone. "Supercapacitors are characterized by large discharge power, and the stored electrical energy can be released in a very short period of time, but it is not sustainable. The characteristics of conventional batteries are just the opposite. It is a continuous discharge device that can provide power for a long time. Supercapacitors are like a 100-meter player, and they have a strong explosive force, while conventional batteries are more like a 10,000-meter player with good endurance. Lamborghini's sports car can use supercapacitors when starting and accelerating overtaking, or when emergency brake energy is fed back. Supercapacitors can be used. The sports car has been accelerated to the highest speed and the battery should be used when the maximum speed is maintained. The battery used in the sports car should be a mixture of supercapacitor and conventional battery,” said Dian Dianbo.

Supercapacitors and conventional batteries are combined in a sports car to avoid high power output from conventional batteries. Correspondingly, the safety of conventional batteries will increase and its service life will be extended. Yan Dianbo said that through experiments, if the supercapacitor is mixed with the battery, the life of the conventional battery will be increased by three times.

There are currently three types of supercapacitors: electric double layer supercapacitors, hybrid supercapacitors, and battery-like supercapacitors. The most basic is the electric double layer supercapacitor, which has an energy density of about 5-10 watt-hours/kg, a power density of more than 6000 watts/kg, a particularly long charge-discharge cycle life, and about 1 million charge-discharge cycles. At the same time it is resistant to low temperatures and can be used at -40 °C. "Super capacitors not only have ultra-high charge-discharge efficiency, but the ratio of discharged power to charged power can reach 98% or more, far higher than conventional batteries, basically how much to put, and its process performance is also very good. It can charge and discharge quickly, but its shortcomings are also obvious, that is, the energy density is relatively low, only 5-10 watts/kg, while the lead-acid battery can reach 30 watt-hours/kg, and the lithium battery is more than 100 watt-hours/kg. ”
