- 2021-08-05 Backup Power Supply Modules with Electric Double Layer Capacitors has been commercialized.
Backup Power Supply Modules with Electric Double Layer Capacitors is:
A backup power supply loading the in-house designed and high-performance EDLC for automotive use
The module uses automotive EDLC (Electrical Double Layer Capacitor) as a power storage element instead of batteries, capable of performing EDLC cell balance control, charge/discharge control, self-diagnosis function, communication functions, etc.
After confirming vehicle ignition ON condition, it starts charging of EDLC. In addition, with the module starting up, it performs self-diagnosis of EDLC condition and circuit condition. When a drop of vehicle battery voltage is detected, it moves to backup mode and starts supplying power to the system.

Advantage of adopting EDLC
*Comparison with the case of a battery loaded as a backup power source
Long operating life
Easy maintenance-free design (expected life 15 years) by adopting a highly reliable cell of the own technology
High reliability
Continuously diagnosing cell deterioration with the self-diagnosis function for preventing operation defect
and function failureCompact and high power
Maximum discharge current per volume is around 4 to 50 times of a battery (EDLC cell)
Superior low-temperature performance
Maintaining static capacitance at -30℃ almost comparable to that at normal temperature.
Flexibility of the mounting posision
Possible to load in a crushable zone (trunk room, etc.)
Applications
- Adopted case - Backup power supply of a brake system -
As a backup power supply when the main power is lost, it can maintain the brake performance same as
in normal time, thereby contributing to the construction of a safety-keeping system.
Introduction of backup power supply module equipped with electrical double-layer capacitors
The backup power supply module is equipped with electrical double-layer capacitors EDLC (Electrical Double Layer Capacitor) as a power storage element instead of a traditional battery.
This movie presents demonstration images of the automotive brake backup using a backup power module enabled by electrical double-layer capacitors.
- Application
As a backup power supply when the main power is lost,
it can contribute to the construction of a safety-keeping system
