Combined with smart grid, home energy storage system (hereinafter, HES) can store clean electricity used for daily life, which is produced by solar energy, wind energy and off-peak electricity. Not only charging electrical vehicle, but also supporting home electric equipment, electricity stored by HES can be used when it occurs electricity shortage or during the period of on-peak. Meanwhile, the redundant electricity stored by HES also can transmit to electricity grid, realizing economic benefit. With the reasonable system matching, HES can make it possible that realize zero discharge.

 HES can realize the following:

• 1. Support home electricity demand, especially in the situation of electricity shortage or nature disaster.
• 2. Store solar energy and wind energy to use for daily life and transmit the redundant electricity back to smart grid.
• 3. Reduce home electricity cost by long-term use of HES.

 HES Technical Features:

• 1. HES has realized intelligentized connection with renewable energy generator, home electrical facility and electricity grid.
• 2. HES use LTO battery cells as energy carrier to ensure user safe.
• 3. Reduce maintenance cost by long cycle life of LTO battery cells with stable performance.
• 4. Achieve the combination of home energy storage and auto energy storage urgently to save the original investment, while is according with the design standard of intelligent architecture and electrical vehicle.
