>“The Zem electric car is also home to bi-directional charging that can be used to charge other items as well. Zem will look like an external battery to your home, providing green energy when needed,” TU/ecomotive has stated.

I can see this being very useful in my home country, Canada. On the east coast the frequency of hurricanes, ice storms and other events causing power outages is increasing. Portable generators have always been popular but many people are buying portable battery packs so they can at least boil some water and make tea or soup while waiting for the power to come back on.

I hope that this kind of bi-directional charging becomes standard for all vehicles in the future; it could be very helpful and lifesaving in the case of emergency situations in natural disasters such as earthquakes, typhoons, etc.
