The world's first electric desk calculator (calculator), which was created in 1963, is a very large size of 376 x 450 x 255mm in size and about 14 kg, and the selling price is equivalent to one car at the time.It is said that it was expensive enough.Such a calculator also made LSI (large -scale integrated circuit), a thin liquid crystal display, and a small power supply, such as button batteries and solar batteries, and even a card -type calculator that fits in your wallet in the 1980s.
Many people are currently using laptops and smartphones, and appliances that have built -in power supply power supply, as if it were a default route, miniatur or thinner in the evolution processIs trying.And the EV is now in the middle of ultra -size, but the common point is to "move with humans."This is because smaller and thinning will increase the convenience and convenience.In particular, in some countries and regions that have many narrow roads like Japan, the need for ultra -small EVs is growing.
There are various models and types in cars depending on the application.It is classified into four categories: ordinary cars, mini cars, ultra -small mobility, and minicar depending on the size and output, and electric vehicles belonging to ultra -small mobility and minicar are called ultra -small EVs.Furthermore, the standard output is 0.The smallest of 6kw is less than 6kw, and the minicar is legally equivalent to the prime bicycle, such as the no need for vehicle inspection, and is sold by JIAYUAN, China and used car sales and purchase companies.Apple "and bamboooka" Millyu R "correspond to this.
Next, the ultra -small mobility includes a "model -designated vehicle" that can omit the carry -on inspection to the land transportation bureau, etc., and a "certified vehicle" that requires a carry -on inspection to the land transportation bureau, etc., and includes gasoline vehicles.Most of the mass -produced cars currently sold in Japan are designated models.
In addition, the smallest size and small turn is the ultra -small EV of the minicar standard.Despite the capacity of one riding, it is expected that the last one mile in the home delivery business and the change of feet used for everyday shopping in order to prevent rain and wind firmly.
On the other hand, the size of the ultra -small mobility is one size smaller than the mini car, the number of rides is 2-4 people, and it is legally necessary to receive a vehicle inspection in the same way as a mini car, and it is the same yellow car.A license plate will be assigned.By the way, the minicar is treated as a moped on the standard (Road Transportation Law), but the Road Traffic Law is "ordinary car treatment", so although there is no obligation to turn right or wearing a helmet, it is not obligatory to wear a helmet, but it is a normal license to drive.This is needed.
Here are some ultra -small EVs from each manufacturer that are currently released or media announced.
Idemitsu Tajima EV is a new company established in April 2021 due to Idemitsu Kosan, a major oil -selling company, and Tajima Motor Corporation, which is planning, designing and manufacturing EVs.The company brings together the material development technology of Idemitsu Kosan and Tajima's EV vehicle design technology, and announced the development of a 4 -seater ultra -small EV that complies with the new standard released by the Ministry of Land, Infrastructure, Transport and Tourism in September 2020.did.
The size of the announced vehicle is 2495 x 1295 x 1765mm in height, and the maximum output is 15 kW, so if it is converted to horsepower, it may feel a little weaker than a gasoline car, about 20㎰ and a maximum speed of 60 km or less.Maybe.However, as the number of car accidents caused by the elderly due to the judgment of the judgment and operation of the operation is increasing, even those who are worried about driving or those who are unfamiliar with driving at low speed driving at 60 km / h or less.It is expected that you can drive with confidence.
In addition, Idemitsu Tajima EVs are developed and provided with sharing and subcusced services and charging infrastructure, utilizing more than 6,000 affiliated SS networks from Idemitsu Kosan.The company plans to create recycling systems for vehicles and batteries at the same time.
On January 3, shortly after 2022, the CES2022, the world's largest high -tech technology trade fair, was held in Las Vegas in the United States.The latest models in the home appliance market, such as TV, game consoles, and PCs, are gathering, playing a role like windows that reflect the future of technology.This time, more than 400 mobility -related companies exhibited proud technologies such as driving EVs and autonomous driving.
The BMW announced, the electric SUV "BMW IX", which can switch the body color simply by pressing the button, and the GM "Chevrolet Silverado EV", which taps about 644km and 664 horsepower, has attracted attention.What I was was in modern Moris's ultra -small EV.
Contemporary Moris exhibited two types of EV -based ultra -small mobility "M Vision Pop" and "M Vision 2GO" of urban -type hydrogen mobility.Was gathered.The company last year, which is a "e-corner module", which is packed in one wheel of four principles, which are originally shared by several parts, such as power transmission, direction change, shock absorption, and braking into these two models.Adopt a new technology that has been developed in October.
Normally, the driving system of the car functions in conjunction with several parts, so there is a limit to the steering angle (tire cut width) due to structure, but this "E-Corner module" is built into wheels.The motor drives independently.Therefore, "club driving", which moves the body like a crab left and right, and "zero turn" that rotates 360 ° on the spot, is possible, and the running agility in a narrow road environment in the city center and the safety of parking.It is said to increase.
In addition, drivers and pedestrians can communicate, functions linking smartphone car navigation systems and in -vehicle displays, and when the driver is attached, the handle is moved to the passenger seat, and driving is transferred to the passengers sitting there.The functions that can be done are also adopted, and they are gathering hot gazes as the next generation car.
As a member of the Toyota Group, the ultra-small EV "Coms", which is released by Toyota body, mainly involved in the manufacturing of minivans and SUVs, has "P-Com" assuming everyday use such as commuting, going to school, shopping.The lineup is "B-COM", which assumes business use such as sales and home delivery business.In each case, the maximum speed is 60 km with the same minicar as the moped motorcycle, it can be fully charged in about 6 hours from the AC100V power supply at home, and it can run about 50 km in one full charge, currently a convenience store major, Seven -Eleven's home delivery service.He is active as the last one mile.
On the other hand, the "C+POD" sold by Toyota Motor Corporation is a two -seater EV with a ultra -small mobility (designated model), which is one size smaller than a mini car, and is in WLTC mode.It is about 150km, so it is enough for everyday use.In addition, with a compact size that is easy to handle even on narrow roads and parking lots, a lithium -ion battery that takes up space is mounted under the floor at the feet, ensuring a spacious floor and luggage space with low steps.
In addition, it supports the safety standards newly established for ultra -small mobility, is equipped with airbags, and is also considered for safety, such as adopting a shock absorption and pedestrian injury reduction body in collision.increase.
To achieve the carbon neutral, it is certainly inevitable to switch from gasoline diesel vehicles to EVs, but that is not enough even if all cars have shifted to EVs.
Because it is an EV that does not emit exhaust gas that harms the global environment, it uses a lot of "petroleum chemical products" such as interior plastic and tire rubber, and in the process of manufacturing and disposal of the main unit, a large amount of co²².Because it is discharged.In addition, even if the power source is electricity, a considerable amount of harmful exhaust gas is discharged in the process of power generation and transportation, especially in Japan, most of the power generation depends on firepower that uses crude oil.
In other words, in conjunction with promoting the recovery of EVs, if the weight of petroleum chemical products by miniaturizing and lighter the vehicle, and the energy efficiency is not performed at the same time, there is no zero of the "CO² emissions and the amount of absorption and removal amount are subtracted.It can be said that it is difficult to do.
Meanwhile, as you can see from the evolution process of mobile home appliances, domestic home appliance manufacturers have a reputation for small size, and have unique small mobility manufacturing know -how that are not in the world of mini vehicles.Utilizing this advantage, it is possible for Japanese manufacturers to gain hegemony in the world's EV market, and eventually the goal of human beings, the path to neutral achievement, may be seen.
