TF900 Meter System Assembly

 

TF900 Meter System Assembly


TF900 meter system is a new generation of electrical system with lithium batteries developed by the company (Patent No. ZL 2018 2 0779153.4) for lithium-ion bicycles and lithium-ion scooters. The whole electrical system is consisted of LCD speed meter, multi-function switch, central controller, controller, and assembly harness, which is designed with a bus concept and is developed based on a bus framework that intercommunicate is enabled by built-in MCU of respective electrical system for electrical components connecting to the assembly harness.


LCD meter:

①Exquisite and ultra-thin LCD, made of 0.7mm glass, with clear display and high brightness backlight.

②No high voltage input, low temperature rise, high reliability.


Multi-function switch:

①Functional integration, and easily set up key functions according to user requirements.

②Convenient operation, and easily switch gear and turn on lights during riding.


Central controller:

①Built-in high-voltage large capacitor module (100V. 2A) provides stable power supply for electrical components.

②According to user needs, integrate electrical load ports, such as headlights, rear lights, turn signals, brake lights, ambient lights and horns.

③Full package of protection functions, protect the whole riding experience from any load short circuit, such as brake short circuit due to water, it will cause braking by the electrical system as artificial brake).

④Uniform interfaces, convenient for assembly.


Controller:

Simple wiring (power supply, motor, and communication) no other expansion functions, focus on motor control.


Assembly harness:

①4-in-1 interface, simple assembly, functional integration. 

 

Features and Benefits of TF900 Meter System Assembly

1、When the assembly harness of meter system is overloaded or short-circuited during the riding process, it will not affect the operation of the scooter.

2、The meter has a full package of functions, including instant start, fixed speed cruise, headlights and rear lights, left and right turn signals, password setting, horn control, mileage/speed display, battery display, fault alarm warning, brake rear flash lights, meeting the requirements of appearance, security and advanced technology.

3、Multifunction switch integrates all the function keys and separates them from the main body of the meter, which is installed at the left handgrip for easy adjustment and corresponds to the meter at the right handgrip, in a way that the left hand controls function keys and right hand controls throttle, reducing the burden on the right hand.

4 、The meter system assembly has a comprehensive configuration, including lithium meter (color screen), left and right handgrips, multifunction switch, controller, central controller, and assembly control cable harness, which saves time and efforts for searching other configuration due to incomplete configuration.

5、The wiring connectors of respective components of the meter system assembly are clearly designed for fast connection to the corresponding connectors when assembling the scooter, which reduces working hours during assembly and improves work efficiency.

6、All the function control connectors of the meter system assembly are designed in the central controller, in this way that the master controller operates on the motor only, thus reducing the workload of the master controller. More importantly, it reduces the probability of failure due to excessive connection tasks.
