supercapacitor

The article presents the structure and operating principles of an electric drive system for a vehicle with a hybrid energy storage system that combines a fuel cell and a supercapacitor connected via controlled DC-DC converters with a common DC bus. The traction drive functions are performed by a brushless DC motor (BLDC) powered by three-phase voltage from an inverter connected to the DC bus.

In modern autonomous electric power supply systems, in particular, for electric vehicles (EV), rechargeable batteries (B) are often used as energy sources and supercapacitor (SC) modules are often used as power sources. To ensure the necessary level of on-board voltage, these devices consist of a large number of low-voltage cells, the work of which is accompanied by complex electronic energy management systems (EMS).
