Chubu Electric Power Co., Inc. (President: Akihisa Mizuno; location: 1, Higashi-shincho, Higashi-ku, Nagoya, Aichi Prefecture) and Aichi Electric Co., Ltd. (President: Isao Yamada; location: 1, Aichi-cho, Kasugai City, Aichi Prefecture) have jointly developed Deco-System, a regular charging system that can charge multiple electric vehicles*1 efficiently at multi-unit housing.
Aichi Electric Co., Ltd. plans to start sales of the developed product on December 01, 2011.
At condominium complexes and other multi-unit housing, electric vehicles are generally charged with a common power source. Common power sources are often used for purposes like hallway lighting at multi-unit housing, so usually there is no great fluctuation in power usage. However, as electric vehicles become more common in future, managers of multi-unit housing will have to deal with certain issues. For example, when multiple vehicles are charging, they will consume a large volume of power temporarily (and higher electric power contracted capacities will be needed). In order to collect fees, moreover, it will need to be determined how much power people are using individually.
The newly developed product has a built in controller with load leveling function. This keeps charging times from overlapping (scheduling considers when each vehicle needs to finish charging) so it can minimize increases in electric power contracted capacities. Additionally, smart cards will identify users so their individual power consumption can be tracked.
Moreover, since the product has a contract and fees management system, it helps managers of multi-unit housing perform contracted capacity simulation*2 and makes appropriate user billing easy to do.
The product will be on exhibit at SMART MOBILITY CITY 2011, taking place at Tokyo Big Site starting on December 02, 2011.
Major features of electric vehicle regular charging system for multi-unit housing
1. Helps stay within contracted capacity
When charging multiple electric vehicles, the controller with load-leveling function can keep charging times from overlapping so that power consumption stays within contracted capacity.
2. Tracks individual power consumption
Managers of multi-unit housing can find individual power consumption levels, number of times charged, usage fees and so on in a table display using individual identification with a smart card and the contract and fees management system. They can additionally simulate contracted capacity and billing methods according to charged vehicle conditions.
Identification is by contactless smart card to prevent tampering by unregistered users.
*1 Electric vehicles (EV) and plug-in hybrid vehicles (PHV).
*2 Load-leveling simulation and contracted capacity can be selected based on conditions, including charged vehicle conditions (number of EVs and PHVs, charge time and charge volume) and contracted capacity. Managers can also select a billing method (by the month, by hours charged, by number of times charged or by power consumption), and also check how much of the cost of the charging equipment, etc. they have recovered.
