Panasonic's new HL series electric double layer capacitor is suitable for the backup power supply circuit used in industrial equipment and automobiles.
Osaka, Japan - Panasonic Corporation announced today that it has commercialized its HL series electric double layer capacitor with the industry's first*1 2000-hour operation life guarantee as a radial lead type. The new capacitor is suitable for the backup power supply circuit of industrial equipment requiring long operation life, such as storage equipment and smart meters, and automobile backup power supply circuits. Mass-production is scheduled to start in January 2017.
With the expansion of IoT and smart grid, demand for a backup power supply is on the rise for such things on the network as smart meters and storage equipment to allow them communicate or store data instantly when a power failure occurs. Industrial backup devices used in such equipment require long operation life without replacement and the capability of instantly supplying high-current output. These devices also require strength to endure outdoor installation in severe environments as well as compact-sizing and lightweight design of the power supply circuit. Panasonic has developed unique electrolyte, which permits the new electric double layer capacitor to not only achieve the industry's first*1 2000-hour-long guaranteed operation life as a radial lead type, but to supply large-capacity current in a low-temperature environment of -40°C.
Backup power supply for industrial equipment such as servers, storage equipment (SSD), smart meters; drive assisting power supply for motor, and actuators; backup power supply for a variety of automotive systems (emergency brakes, door lock release, etc.); auxiliary power supply circuit for solar cells
Electric double layer capacitors used in the backup power supply of industrial equipment are required to operate for a long period of time. In a backup power supply for automotive emergency brakes, door lock release system, etc., a compact and lightweight design is required in addition to long operation life. Panasonic's proprietary development of an electrolyte allowed it to reduce the deterioration of characteristics such as capacitance and internal resistance; consequently, the company was able to achieve the industry's first 2000-hour guarantee with radial lead type electric double layer capacitor. This enables the designer of a power supply circuit to use fewer capacitors at the time of the initial design.
Backup applications of industrial equipment require instant discharge of large current. Previous capacitors had difficulty in rapid discharge of large current due to the high internal resistance because of the high conductivity of the electrolyte. With the development of the unique electrolyte with improved conductivity, internal resistance has been reduced and flowing current has been increased even by using non-acetonitrile-based (AN) electrolyte to the level comparable to or more than those using acetonitrile-based (AN) electrolyte for supplying the rapid charging and discharging required by industrial and automotive applications.
An increasing amount of industrial equipment is used in severe-temperature environments. Smart meters, in particular, are expected to operate outdoors in cold-weather environments, and the capacitors used in a backup power supply are required to operate in the same low temperature. In general, the conductivity of an electrolyte is reduced in low temperatures and internal resistance increases accordingly to deterioration characteristics, thus the low temperature guarantee of the company's conventional radial lead type electric double layer capacitor was limited to -25°C. However, this new HL series product has achieved a guaranteed operating temperature of -40°C through the development of this new electrolyte, and it can satisfy the ANSI standards of the United States. Therefore, this product is suitable for equipment installed outdoors such as smart meters as well as automotive applications in cold weather.
