The Electric Vehicles rapid charger on the other hand is used at EV rapid charging stations, which are expected to rapidly increase in number. It boasts a charging time of approximately 25 minutes for 80% of electric car capacity, which is remarkably faster than the 8 to 14 hours necessary with ordinary chargers.
As part of the new business undertaken by the Corporate Customers Support Division, ULVAC worked jointly with its subsidiary, Reliance Electric Ltd. (Head Office: Yokohama City, Kanagawa, President: Mr. Junichi Ishizaki) for the development and launch of these systems. ULVAC and Reliance Electric are worldwide manufacturers of photovoltaic cell manufacturing equipment and electric variable drive control equipment respectively. Consequently, Reliance Electric has power conditioner (DC-AC power converter) manufacturing technology, which forms the core of photovoltaic power generation equipment, as well as electric design technology which is required for electric cars rapid chargers.
In particular, the EV rapid charger developed and manufactured by Reliance Electric uses technologies developed for ULVAC sputtering equipment power supplies, which have global market share by an overwhelming margin. This EV rapid charger also conforms to the standards set by Tokyo Electric Power Co.
The photovoltaic power generation and rapid charging system developed and launched by ULVAC can use utility power during the night and days when there is little sunshine. When it is not used for charging EV, the power generated by photovoltaic cells can be purchased by electric companies through system linkage, making the effective utilization of the generated electric power possible.
The photovoltaic power generation and rapid charging system, for which ULVAC has received an order from Chigasaki City, consists of photovoltaic cells to be installed on the roof of the municipal parking lot (initial power generation 20 kW), power conditioners, rapid chargers (50 kW), normal chargers, power generation control monitors, and so on. The system also enables citizens to monitor the status of the electric power generated by photovoltaic cells through a display installed at Chigasaki City Hall via wireless communication. This system will be installed at the municipal parking lot located at Chigasaki 2-chome, Chigasaki City by March 2010.
Furthermore, ULVAC has installed practically the same system in its own backyard, the parking lot of ULVAC Chigasaki Head Office Plant, for the purposes of demonstration. The system consists of photovoltaic power generation facilities featuring thin film system photovoltaic cells and rapid chargers.
By using this demonstration system, ULVAC will carry on its research and development with the aim of achieving photovoltaic power generation systems and EV rapid chargers with higher efficiency.
ULVAC’s target sales for the first year of this product is one billion yen for combination systems comprising photovoltaic power generation and EV rapid chargers, photovoltaic power generation systems, EV rapid chargers, control monitors, etc. ULVAC has 37 affiliated companies in major overseas locations and will market aggressively not only in Japan but also overseas.
Our EV rapid charger and the system combining it with a power generation facility will be presented at the ULVAC booth (West 8-44) of the First EV and HEV Drive System Technology Fair, to be held at Tokyo Big Sight, Ariake, Tokyo from January 20 (Wed) through 22 (Fri), 2010.
ULVAC(Ultimate in Vacuum), Inc. has been a leader in vacuum technology industry since its establishment in 1952. The company has always provided lines of equipment and production systems that form the core of state-of-art production processes in the areas of Flat Panel Displays, Solar cell, semiconductor, electronics. The company has not only provided equipment but also materials, analysis, evaluation and other service, which are integrated into ULVAC Solutions.
