Sharp developing Intelligent Power Conditioner enabling EV batteries to be used as storage batteries for home power
Sharp Corporation has developed an Intelligent Power Conditioner that enables batteries in electric vehicles to be used as storage batteries for the home. Sharp will be conducting tests to confirm the safety and reliability of this system, with the aim of making this device commercially available in the near future.

The Intelligent Power Conditioner (power inverter/controller) is based on power control technology Sharp has developed over the course of developing power conditioners for PV generation systems. With the Intelligent Power Conditioner, solar cells and storage batteries operate in conjunction with utility power to supply electrical energy on a consistent basis. In anticipation of future DC home appliances, this system can also supply DC electricity.
The technology can make use of EV traction batteries as part of a residential power storage system. In proof-of-concept trials, Sharp succeeded in using a battery pack in a commercially available iMiEV to supply 8 kW of power—enough to power electrical appliances in an average household. In addition, the charge controller in the Intelligent Power Conditioner was able to deliver 4 kWh of energy to recharge the electric vehicle battery pack in approximately 30 minutes.
Sharp will be pursuing R&D aimed at the early commercialization of this Intelligent Power Conditioner.
In the context of making the Eco House concept a reality, Sharp is focusing on three themes: solar cells, storage batteries, and DC (direct-current) appliances.
