FDK Corp has introduced the ECM15P series of EneCapTen ultra capacitor modules for use in vehicles. The product series is claimed to provide high power with long life and an optimal thermal performance of up to 80°C.
As modularized versions of its original high-capacity EneCapTen capacitor, the 15V ultra capacitors have a long cycle life of over 500,000 cycles, a high power density relative to batteries, and an efficiency rating of 99.9%. Measuring 260 x 210 x 60mm in size, they have 525F of capacitance, 10.5Wh of energy capacity, and 5kW of maximum power. As these modules can charge and discharge both by a high power supply of several hundred amperes and a low power supply, they have many applications for use in vehicles.
By using the ECM15P series, it is possible to set up a compact idling stop system which can regenerate electric power during deceleration. The modules also extend the product life of lead acid batteries or lithium ion batteries which are used alternately or simultaneously with the ECM ultra capacitor.
The good thermal performance of the SSDs makes it possible to place near the engine, thus reducing the length of the electric wires and the resistance loss. The modules are said to be environmentally friendly, safe, and secure. They do not use heavy metals or flammable materials thus they will not rupture and ignite. They are equipped with balance circuits to equalize each cell's voltage, protection circuits to prevent over charge and discharge, and have an advanced power management system with microcomputer control as standard equipment.
