An electric car, battery car, or all-electric car is an automobile that is propelled by one or more electric motors, using only energy stored in batteries. Compared to internal combustion engine (ICE) vehicles, electric cars are quieter, have no exhaust emissions, and lower emissions overall. In the United States and the European Union, as of 2020, the total cost of ownership of recent electric vehicles is cheaper than that of equivalent ICE cars, due to lower fueling and maintenance costs. Charging an electric car can be done at a variety of charging stations; these charging stations can be installed in both houses and public areas. Worldwide, 6.6 million plug-in electric cars were sold in 2021, more than doubling 2020 sales, and achieving a market share of 9% of the global new car market. All-electric cars represented 71% of plug-in car sales in 2021. As of December 2021, there were 16 million plug-in electric cars were on the world's roads. Many countries have established government incentives for plug-in electric vehicles, tax credits, subsidies, and other non-monetary incentives while several countries have legislated to phase-out sales of fossil fuel cars, to reduce air pollution and limit climate change. The Tesla Model 3 became the world's all-time best-selling electric car in early 2020, and in June 2021, became the first electric car to pass 1 million global sales. Earlier models with widespread adoption include the Japanese Mitsubishi i-MiEV and the Nissan Leaf.

A remote control car is a model car that can be remotely controlled by a 2.4GHz radio remote control. Generally can be divided into: toys, car models (R/C), police and other categories. According to the appearance of the car body, it can be divided into: RV (flat sports car), off-road vehicle, big truck, rally car, container car, etc. The remote control model car is referred to as RC Car. The remote control model car is not a toy. It is actually a "reduced version of a real car". It has the same power system (engine, gear) and suspension system as the car. F1 is equivalent to a centrifugal force of 4 Gs. It also has the handling feel of those super sports cars in real cars. Electric remote control model car (referred to as tram) is the first choice for many beginners, because it can be charged as long as there is an "electric place", a fully charged battery can drive the car to walk, and the inertia of the tram is small, and the control skills are in " "Entry-level cars" are easy to master, and the speed of electric cars is very fast: it can easily reach more than 60KM, and the speed of electric cars is not slow at all. The linear output of the electric car is good, and the weight is lighter than that of the oil car, so the control of the electric car is flexible, and the speed of the curve is often higher than that of the oil car. The results are often faster than the gasoline car. The precision and sensitivity of competition-level electric vehicles are amazing. Most of the frames are made of carbon fiber, and most of the metal parts are: titanium alloys and the highest-grade aluminum alloys. The whole vehicle has more than 12 adjustable parts to adapt to different venues.

The kids car is a large category of children's toys, including five categories of children's bicycles, children's strollers, baby walkers, children's tricycles, and children's electric vehicles. Children's bicycles are suitable for children's age range from 4 to 8 years old. When purchasing, choose the appropriate size according to the age and height of the children, that is, bicycles with a saddle height in the range of 435 to 635 mm. This is a kind of tool car for children to play with. There are various models. Generally, children from 1 to 2 years old play with a stroller, and children over 2 years old play with a toy car with wheels. The stroller will be given to children. The intellectual development of the child brings certain benefits and increases the child's brain development. Clockwork, battery, inertial, or other powered mechanisms of toys should be enclosed and should not expose sharp edges, sharp points, or other dangerous parts that could crush fingers or other parts of the body.
