清水建設
In Japan, the Shimizu Corporation has set up a microgrid (see Section 5.2) in a commercial building. The ‘smart building’ system, which includes 163 UltraBattery cells (500 Ah, 2 volts), also monitors cell voltage, impedance and temperature. A second system, installed at Furukawa Battery's Iwaki Factory, incorporates 192 UltraBattery cells, a 100 kW power conditioning system and a battery management system. This load-levelling application was set up to control the factory's demand for power.
