I want electricity in the event of a disaster!

At around 9:26 pm on April 14, 2016, an earthquake with a magnitude 6.5 and a seismic intensity of 7, which is the epicenter of Mashiki -cho, Kamijo -gun, Kumamoto Prefecture, occurred.After that, you may have seen it in NHK News, etc., but the Mitsubishi Motors' Outlander PHEV, which was stored in the battery, was aired in front of the power outage.

Is the battery going up with a normal gasoline car? that's right. The small battery mounted on a gasoline car has a small capacity, and when electricity is removed from the headlights or cigar socket (now a car called accessory socket), the battery will rise immediately and the engine will not be able to start. I will go. It's OK if you keep the engine on it, but you'll be distracted if there are many people around you or late at night. Electric vehicles and plug -in hybrid vehicles, or PHEVs, are equipped with very large batteries for driving. The example of the battery capacity is as follows. By the way, 1kWh is the amount of power that can light 1000W lighting for one hour consecutive hours. The bulb used at home is about 40W-100W. 1000W will use it outdoors, such as the lighting used at the construction site, and will lightly illuminate the surrounding area.

The above two models are electric vehicles, Outlander is PHEV, and Prius is a hybrid car.As for the differences between electric vehicles, PHEVs, and hybrid vehicles, the battery capacity is generally the most powered vehicle, followed by PHEV and hybrid vehicles.Electric vehicles do not have an engine, so it is natural to need a lot of electricity.

By the way, if you encounter a disaster in bad luck, the lifeline may be cut off. For example, in a case in Mashiki -cho, Kumamoto Prefecture, as of 10:00 pm on the 14th, the power outage was 16,000, gas supply was suspended, and the number of water -cut units was unknown. At 7:00 am on the 15th the next day, the power outage was 14,500 units, gas supply was suspended 4600, and the water was cut off. At 10:00 pm on the 15th, 900 power outages, 478 gas supply stopped, and 85,000 water cuts. At 8:00 pm on the 16th, probably due to the aftershock, the power outage increased to 83,300 units. On the afternoon of the 17th, there were 76,000 power outages, 105,000 gas supply suspension, and 275,000 water shuts. At 21:00 on March 17, a power outage was 38,900, and the power outage was 34,700 at 10:00 on the 18th. In many disasters, electricity is often restored first. However, if the electricity does not come for the first day, the things in the refrigerator will be useless, there is no light at night, and the microwave oven is not used, so it is very troublesome.

There are also electric vehicles, PHEVs, and hybrid vehicles that can extract electricity from cars.There are three ways to take this out, and it is necessary to use them properly depending on the situation.Please be careful when considering disaster countermeasures.

Even 1500W is encouraging in the event of a disaster.Basically, the cigar lighter is for leisure, the 1500W is for outdoor and emergency, and the 6000W is for those who want to make a disaster prevention house.

What is V2H?

V2H is an abbreviation of Vehicle to Home, which is a mechanism that usually charges electric vehicles and PHEV from home power supply, but supplies electricity from the car side when necessary.This requires V2H compatible vehicles and power conditioners as described above.Here are the power conditioner below.

Oh, it's pretty expensive.And the 6000W = 6kw type that can take out high output is installed at home, and cannot be loaded on a car.However, this type has a large capacity, so it can cover the power of one house, and there is also an electric vehicle charging function.The two of the 1500W type may be considered an additional option for Nissan Leaf and Mitsubishi I-MIEV not have a 1500W outlet.For example, the Mitsubishi Outlander PHEV can add a 1500W outlet for a manufacturer option of 70,000 yen, so these are not required.

In the first place, V2H is not a "dedicated" facility for disaster countermeasures. Depending on the power company, we may provide a plan that makes the daytime electricity expensive. If you do not use a weekday car, you can connect to V2H, live on electric vehicles in the daytime, and charge cheap electric vehicles with cheap electricity at night. In addition, if you are doing solar power, you can sell 100%power in the daytime (sell electricity to electricity companies) and supply missing electricity from electric vehicles. If the power of solar power is large enough, you can save a lot of electricity bills. In the event of a disaster, combined with electric vehicles to generate electricity in sunlight in the daytime, and use it at home and charge electric vehicles. If you use electric vehicles at night, you can withstand power outages for a long time. For reference, it is actually difficult to be independent of power companies (called off -grid). Because the weather may continue, the electricity of the electric vehicle will be empty when there are no sunny days for more than a week.

In conclusion, how do you use V2H?

First of all, if you get 1500W with a model with a 1500W outlet, and a simple power conditioner like a leaf or i-mieV (usually such a single function is called an inverter), It is a good idea to consider it for emergency lighting, charging mobile phones, and television and radio. Of course, it can be used for cooking outdoors in flat times, but at home, multiple devices such as refrigerators, air conditioners, and microwave ovens work at the same time, so it is possible to cover them one by one, but all power can be done. It is not enough to supply. A full -fledged V2H system has two purposes. One is disaster countermeasures, and the other is the efficiency of solar power generation. The former is rarely caused by disasters, so it is a preparation for the emergency. It's like insurance. And at the moment, the latter is not a big deal at the moment (of course it will be a plus), so I think it is better to introduce it if you have a desire to cooperate with the CO2 reduction yourself. increase.

List of cars that can supply external power in the event of a disaster

Finally, we made a list of cars that can supply power outside during a disaster.Please do it for your reference at the time of purchase.

Surprisingly, many Toyota's hybrid cars are compatible with 1500W outlets. Because it is a hybrid, you will not be able to supply power unless you leave the engine on it, but in emergency it will be useful enough. ( * 2016/4/19 Postscript: For Toyota's hybrid cars with 1500W outlets, the battery charging level will vary depending on the timing, and the engine will be used with the engine, but if the power consumption is small, the engine will be stopped automatically. However, it was said that it will restart as needed. Also, if you use the power with the engine, it is not only in the event of a disaster, but be careful of the idling stop ordinance in normal times. ) And what about electric vehicles? Leaf and i-mieV can supply power up to the battery capacity, but they do not have gasoline engine tanks like Outlander PHEV, so as a total power supply. It seems that plug -in hybrid cars can supply more power. However, it seems that there are many cases where gasoline is not available in the event of a disaster (we have heard that there are more than 100 waiting queues at the gas station this time), so even in electric vehicles, if the battery is low, the power is restored. If you move to the quick charging spot you are doing and charge it, you will be able to use electricity again, and both can be said to be a car that is resistant to disasters.

Speaking of which, there are no overseas electric vehicles and plug -in hybrids on the list, right?In fact, Tesla, BMW, Mercedes, etc. (EV/PHEV list here is here) also sells cars, but these manufacturers do not support V2H, but also in -car outlets.For example, in the United States, there are many outlets in the campsite (parking space and tents are adjacent and borrowed), so taking power from cars is only needed for camping cars.I do.Looking at the KOA in Lake Tahoe, it is Full Hookup, which is generally not only power (30A), but also a place where water supply, sewerage, and cable TV and telephone lines can be connected.。In the United States, 18.3%of the detached families have a generator.

Reference: The EVSMART app has entered the list of charging spots that were actually used after the earthquake in Kumamoto Prefecture, which were announced by the Japanese charging service, so that they can be easily viewed. If you are affected by the disaster / support person, if you are using an electric car or PHEV, press the current button, tap the icon of your nearby charger, and write the distance to the charging spot and the spot. If you can tap the place again, you can see the information like a screenshot on the right. We will update if there is additional information from the Japanese charging service. This information is a spot that was actually charged after the earthquake, so there is a possibility that other spots can be charged. It seems that there are places where the road is cut off, so be careful. It would be helpful if you could use the "usable report" and charger photos by users.
