Old car, also known as old-age electric car, old-age scooter, elderly bicycle, is the elderly outdoor travel

Ideal vehicle for transportation. Its performance is relatively stable, the speed is slow, use electricity need not refuel, it is also known as environmental protection old car, the elderly electric vehicles used in a lot of energy, mainly lead-acid batteries (including lead-acid colloid batteries), Ni-MH batteries, nickel-cadmium batteries, nickel-iron batteries, lithium-ion batteries (often referred to as lithium batteries), fuel cells and so on. The battery converts chemical energy directly into electricity by electrochemical means. It does not pass through the heat engine process, therefore is not limited by the Carnot cycle, the energy conversion efficiency is high ($number), almost does not produce NOx and SOX emissions.

The current market appears a variety of sell of the so-called "old-age scooter", not only confused with the elderly friends of the audio-visual, but also to the elderly driving the safety of the disabled, the Government has issued relevant policies and regulations, prohibit these "old-age scooter" on the road.

In strict sense, the real elderly electric scooter products should be from the original belonging to the medical device category of electric wheelchair evolution, product design more suitable for the elderly, disabled driving habits. And the application of people from the former electric wheelchair disabled group extended to the vast number of elderly people with inconvenience. Product design and production refer to the national standard of electric bicycles and the national standards of electric wheelchairs, in some parameters are even more stringent than the above 2 national standards, speed design within 10 km/h, vehicle chassis height in 8cm, brake braking distance within 0.5 meters, from all aspects are superior to the original electric wheelchair vehicle, is the evolution of electric wheelchair vehicles upgraded models, to meet the majority of elderly friends travel needs, while providing a more comprehensive security.

The difference between old-age scooter and electric electric car

Many electric cars sell electric cars as elderly scooters. But in fact, electric cars and old-age scooters are completely different from their appearance and safety systems.

Electric cars must drive and license on the road

And the old-age scooter does not need a licence and a driver's license on the road. Many businesses will be electric vehicles as old-age car to customers, the result of the elderly bought a car after the road by traffic police caught. So in the car must remember that electric cars are not old-age scooter.

Part

The general old-age scooter is composed of battery, electric hub, controller, charger, four parts and body parts. For the safety has higher requirements of the Taiwan manufacturers, according to the design of the vehicle design ideas for the whole, the vehicle is generally divided into the power supply system, the front axle, rear axle, controller, frame and other parts.

Because the current lithium-ion cost is relatively high, the general manufacturers are using lead-acid batteries, generally by a group of batteries from a number of 12V battery series into a battery pack, as a power supply system. According to the relevant state regulations, electric vehicle voltage shall not exceed 48V;

Motor Hub is divided into: there is a brush teeth high-speed electric wheels (referred to as high-speed motor or audio motor), brush-free low-speed electric wheels (referred to as low-speed Motor or silent motor) and brushless program motor (motor);

The controller is classified according to the control mode of the total dynamic type, intelligent type, double control type and non 0 starting type four types, the control system is controlled by the main controller, instrument display, speed transfer and braking power, and other components, its main functions are stepless speed regulation, braking power protection, undervoltage protection and over-current protection and other functions; The charger according to the output plug classification has Lotus plug type, ordinary computer plug-type, special computer plug-type. According to the charge performance classification for general online maintenance charger, fast charger online maintenance. According to the charge voltage classified as 24V, 36V, 48V.

Controller

Briefly speaking, the controller is composed of peripheral devices and main chip (or MCU). Peripheral devices are a number of functional devices, such as execution, sampling, etc., they are resistors, sensors, bridge switch circuit, as well as auxiliary MCU or ASIC to complete the control process of the device; MCU is also called microcontroller, it is the drive circuit to control the speed of the motor by integrating the memory device, the decoder with the transform signal language, the sawtooth wave Generator and the pulse width modulation function circuit and the conduction time to control the power tube through the square wave. Input and output ports are integrated into a computer chip. This is the intelligent controller for old-age electric vehicles. It is a "fool" appearance of High-tech products.

The design quality, characteristic, the function of the microprocessor, the circuit of power switch device and the layout of peripheral devices are directly related to the performance and running state of the vehicle, as well as the performance and efficiency of the controller itself. Different quality controllers, used in the same car, with the same charge and discharge status of the same group of batteries, and sometimes in the ability to continue to show a greater difference.

Motor

Old electric cars commonly used motor is DC motor, with, no permanent magnet classification, there are permanent magnet motor and series of two types of motor. The rotating part of the motor is called the rotor, and the part that does not rotate is called the stator. The rotor or stator of a permanent magnet motor is a permanent magnet, and the other one is a wire wrap around the enameled wire; The same power of the motor, permanent magnet motor than the series-excited motor power. Permanent magnet Motor magnet is afraid of high temperature, the quality of 110 degrees will be demagnetization, good quality can be to 140 degrees; the string motor does not have permanent magnets, there is no such problem.

In the market of the elderly electric cars, motor power generally in 400 watts-900 watts, are using a series of motor, string motor belongs to the brush motor. A 300-watt walk around the line, general use of permanent magnet motor. Old electric bicycle motor is generally 180 watts-250 watts.
