Old car, also known as old electric car, old scooter, old bikes, is the elderly outdoor travel

Old scooter manufacturers

The ideal vehicle to travel. Its performance is relatively stable, slow speed, the use of electricity without fuel, it is also known as environmentally friendly old car, the elderly electric car used a lot of energy, mainly lead acid batteries (lead-acid battery), nickel-metal hydride batteries, nickel cadmium Batteries, nickel-iron batteries, lithium-ion batteries (often referred to as lithium batteries), fuel cells. The battery converts the chemical energy directly into electrical energy by electrochemical means. It does not go through the heat engine process and is therefore not subject to the Kano cycle, with high energy conversion efficiency (40-60%); almost no emissions of NOx and SOx.

The current market there have been a variety of sheepskin selling dog meat so-called "old scooter", not only confuse the elderly friends of the audio-visual, but also to drive the elderly, disabled people bring great security risks, local governments are Have introduced the relevant policies and regulations, prohibit these "old scooter" on the road driving.

Strict sense, the real old electric scooter products should be from the original belong to the medical device class electric wheelchair evolved, the product design is more suitable for the elderly, disabled driving habits. And the application of the crowd from the original electric wheelchair disabled population extended to the majority of legs and feet inconvenience of the elderly. The design and production of the products are in accordance with the national standards of the national electric bicycle and the national standard of the electric wheelchair. In some parameter indicators, it is even more stringent than the above two national standards. The speed is designed within 10 km / hour. Height of 8cm, brake braking distance of 0.5 meters, from all aspects are better than the original electric wheelchair, is the evolution of electric wheelchair upgrade models, to meet the needs of the majority of older friends travel travel, while providing more comprehensive Of security.

Older scooter and electric car difference

A lot of electric car business will be called electric vehicles for the elderly scooter sales of the elderly. But in fact the electric car and the old scooter from the appearance and safety system is completely different.

And the elderly scooter on the road without a license and driver's license, electric car on the road car must be on the license, and test driver's license. Many businesses will be electric vehicles as an elderly scooter to customers flicker, the results of the elderly after the car was bought by the traffic police caught. So in the car must remember that electric cars are not old scooter.

component

General old scooter is composed of batteries, electric wheels, controllers, chargers, four parts and body parts. For the safety requirements of the Taiwan manufacturers, according to the design of the car's overall design, the vehicle is generally divided into power supply system, front axle, rear axle, controller, frame and other parts.

As the current relatively high cost of lithium, the general manufacturers are using lead-acid batteries, generally by a group of batteries are connected by a number of 12V battery into a battery pack, as the power supply system. According to the relevant provisions of the state, the electric car's voltage shall not exceed 48V;

The motor hub is divided into: brushed tooth high speed electric wheel (referred to as high speed motor or acoustic motor), brushless toothless low speed electric wheel (referred to as low speed motor or silent motor) and brushless toothless program motor (referred to as program motor)

The controller is divided into four types: dynamic type, intelligent type, double control type and non-zero start type. The control system is composed of main controller, instrument display, speed control switch and brake power switch. Function with stepless speed regulation, brake power protection, undervoltage protection and overcurrent protection and other functions; charger according to the output plug classification Lotus plug type, ordinary computer plug type, special computer plug type. According to the charging performance classified as ordinary online maintenance charger, fast charge online maintenance charger. According to the charging voltage classification for the 24V, 36V, 48V.

Controller

Briefly speaking, the controller is composed of peripheral devices and main chip (or microcontroller). Peripheral devices are some functional devices, such as the implementation, sampling, etc., they are resistors, sensors, bridge switch circuit, and auxiliary single-chip or dedicated integrated circuit to complete the control process of the device; microcontroller, also known as microcontrollers, A memory, a decoder for converting a speech signal, a sawtooth wave generator and a pulse width modulation function circuit, and a turn-on time for controlling the power flow of the switching circuit by turning on or off the power circuit of the switching circuit and controlling the conduction time of the power tube by the square wave Of the drive circuit, input and output ports and other integrated together to form a computer chip. This is the elderly electric car intelligent controller. It is a "fool" appearance of high-tech products.

The design quality, characteristics, the functions of the microprocessor, the power switch device circuit and the surrounding device layout are directly related to the performance and running status of the vehicle, and also affect the performance and efficiency of the controller itself. Different quality of the controller, used in the same car, equipped with the same group of the same charge and discharge state of the battery, and sometimes in the driving ability to show a greater difference.

Motor

Elderly electric cars commonly used motor is generally DC motor, with or without permanent magnet classification, there are two types of permanent magnet motor and series motor. The part of the motor is called the rotor, and the part that does not rotate is called the stator. Permanent magnet motor rotor or stator has a permanent magnet, and the other is the enameled wire wound package; string motor and stator stator winding wire is wrapped around the line package. The same power of the motor, permanent magnet motor than the string motor power. Permanent magnet motor magnet afraid of high temperature, poor quality of 110 degrees will be demagnetized, good quality to 140 degrees; string motor does not have permanent magnets, there is no such problem.

Older electric cars on the market, the motor power is generally 400 watts -900 watts, are used series motor, string motor is a brush motor. Travel three rounds of about 300 watts on the line, the general use of permanent magnet motor. Elderly electric bicycle motor is generally 180 watts to 250 watts.
