Punch press, hydraulic shearing machine, pipe bending machine, welding machine, injection molding machine, spray painting station, oven, and air compressor are required. It costs about 300,000, including the cost of procedures and hiring personnel.

1. Electric vehicles are electric vehicles, also known as electric vehicles. Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Generally speaking, electric vehicles are vehicles that use batteries as the energy source and convert electrical energy into mechanical energy for movement through controllers, motors and other components to control the size of the current and change the speed.

2. The share of electric vehicles in the national economy is not very high. However, it conforms to the national trend of energy conservation and environmental protection, greatly facilitates short-distance transportation, and most importantly, plays an important role in the national economy by saving and protecting energy and the environment.

3. Configuration An electric bicycle is composed of four major parts: battery, electric wheel hub, controller, charger and body part.

IV. Classification of electric vehicles

Electric vehicles can be divided into: electric bicycles, electric motorcycles, electric unicycles, electric four-wheelers, electric Tricycles, electric scooters; divided according to power source: pure electric vehicles, extended-range electric vehicles, hybrid electric vehicles, fuel cell vehicles.

According to the way power is provided, it can be divided into two categories. One is to connect an external power source to obtain power, and the other is to use fuel cells, energy storage devices (such as energy storage batteries, supercapacitors), etc. as power.

Classified by driving mode: pure electric vehicles, hybrid electric vehicles (series, parallel, hybrid), fuel cell electric vehicles.

According to appearance, it can be divided into electric unicycles, electric bicycles, electric motorcycles, electric tricycles, and electric four-wheelers

Classified by use: electric vehicles; electric tricycles; Electric bicycles (comparable to bicycles);

Electric motorcycles, electric trucks, electric patrol cars, folding bikes, surf bikes, scooters, motorcycles, wheelchair strollers, ATVs, scooters, electric balance bikes , Electric sightseeing cars, electric golf carts, electric sanitation cars, electric buses, electric police cars, electric forklifts, magnetic cars, electric trucks, electric tractors, electric rail cars, electric mopeds, electric garbage trucks, electric recreational vehicles, Electric fuel-assisted cars, electric classic cars, light lithium electric cars, other solar electric cars, etc. In addition, there are safety electric vehicles, anti-theft electric vehicles, anti-freeze wall electric vehicles, etc.

Four. Configuration: An electric bicycle is composed of four major parts: battery, electric wheel hub, controller, charger and body part.
