In Ohio, as an intelligent network project, which allows the lithium-ion battery for the network service of the community.

International Call Battery (Battery Internatioanl) launching the company announced it has chosen the lithium-ion battery storage of energy as a pilot project for the community of the company, the project launched by the utility AEP will be online this year.

International Battery Co., Ltd. CEO Ake AlmgrenPA3282U-1ACA,PA3083U-1ACA,PA3282U-2ACA, said the storage unit with refrigerator-size project similar to the core network connected to it and is responsible for driving high-current voltage for local service.

The Fellowship of the energy storage project, part of the U.S. intelligence network, AEP companies are installing smart meters and other technologies designed to reduce the residents of northern Ohio in an area of 150 square miles of energy consumption. AEP revealed that the project sponsored by the Department S. U. Energy will be officially launched in May this year, the project will run until mid next year.

AEP had been at the forefront of storage technology for the power grid, this technology allows power plants to use more intermittent wind and solar power, decrease of peak demand for electricity. AEP has installed a number of substations in Japan Insulator (NGK INSULATORS, LTD.) Company of sodium sulfide batteries, the battery can provide 1 MW and 2 MW of electricity for a few hours.
The project will use smaller batteries and different technologies, power generation company plans to install at each site at least 25 kilowatts of electric power storage unit, which can provide 1-hour electricity supply. AEP is expected to use a different setting, but the company has selected 10 sets of memory cells, these memory cells can store a total of 2 megawatts of electricity.

Energy companies hope that these relatively small volume of the energy storage unit consisting of a network capable of providing the same service with large-scale power plants, for example, to the electricity grid during peak power periods, or in providing mains power outage backup.

International Battery Inc. Almgren, said: “You can mix these batteries for domestic energy supply. These memory cells requires intelligence, may be different depending on time of day and the different prices and decided to supply power and storage time. ”

S & C Electric systems integrator for the project, the company said a distributed memory architecture reduces power transmission when the power loss, you can get the mains more convenient use of wind energy and energy community solar. Almgren said, a single unit of 25 kW of the storage battery of five families, or shopping center to provide electricity for about 1 hour.

The project also uses high voltage protection technology, the power generation companies worry that if multiple users within a community of truck, which will affect the local power grid load, the voltage protection technology overload can solve this problem.

Project long-term goal is to use community-based electricity storage to form a network, the main power supply to maintain stability.

Electricity storage experiments also use a variety of techniques, such as “Speed On” (fly), giant cells, and even the ice with the help of air conditioning equipment technology. A123 Systems lithium-ion announced in November last year, the AES power company in Chile, the 12-MW battery to the main electricity transmission network.

Almgren that once the community that large-scale electric power system and the centralized storage system has some differences. On drums, International Battery manufactured batteries can PA3097U-1ACA,PA3396U-1ACA,PA3467U-1ACAstore more energy, taking up space. Do not use hundreds of thousands of internal cylindrical cells, used by international business groups drummer diamond cell, the size is only the size of bricks.

Almgren, said: “With these groups of cells, can monitor and control a single cell, allowing us to optimize the system as a whole.”

Although the technology is quite simple in theory, the power storage system of the community, before the widespread there are still some technical and business challenges.

First, the battery storage is relatively expensive, energy companies, according to the traditional approach is difficult to make ends meet. Technically, small storage unit for electricity, there are some technical problems must be addressed, such as temperature, reliability, and other intelligent network components, such as smart meters, etc. communication problem.
