Ultracapacitors

Ecologically clean traction storage batteries of ultracapacitors are current sources with quick recharging and long battery cycle life. Less charging time is required compared with that of storage batteries. These traction storage batteries are intended for electric power supply to various low-and medium-power using equipment upon which stringent requirements are imposed by ecological safety, battery cycle life and availability for service.

At the present time, ZEM produces ultracapacitors BKDT-30
