6KW controller


1. Product Overview
PE-EX is specifically designed for Electrical cars by Aoqiang Electronic Technology Co., Ltd. We use high-performance ST processor and advanced FOC technology in the PE-EX product. Benefit from high-performance CPU and advanced control algorithm PE-EX has low noise and smooth acceleration. PE-EX Controller meets the industry EMC and EMI standards, and has been exported to Netherlands, Argentina and other countries. We have many customers and partners in many countries around the world.

1.1 Scope of application
This controller is applicable to drive any DC brushless motor with 120 degree hall sensor, and nominal power under 4KW.Different motors should be configured with our controller before the application. Moreover,different power category controllers can be customized according to the customer application.
1.2 Characteristics
1) Using intelligent and powerful microprocessor of STM32, the controller realizes Field Oriented Control (FOC). It drives the motor with pure sine wave mode to reach a smoother and more quite performance during acceleration and running.
2) With 3 phases and 120 degree hall sensor input, the controller gives power supply to hall sensor and output pull-up.
3) With USB interface, the User can reprogram to upgrade firmware version or change settings for the controller with laptop.
4) Easy trouble shooting: the controller can give out impulse signals when it finds a problem, these impulses can flash a led or shown on LCD with programmed device.
5) Voltage monitoring and control: the controller can limit the output of current when the voltage of the battery is too high or too low than the setting, it can stops the output if necessary for safety.
6) The controller provides 3 modes of current control: starting current, constant current and boost current.
The parameters can be set by the user to drive with economic mode for longer ranger or to drive with boost mode for better acceleration performance or climbing.
7) Temperature control functions: The controller has temperature protection both for itself and the motor (temperature sensor must be planted inside the motor). If the temperature of the controller is more 85C, a warming signal will be given and current is automatically limited to a set value, when the temperature is more than 110C, the controller will shut down current output for protection.
8) Over current Protection: when the current in the circuit is too high, the controller will shut down output and even cut off the power supply to prevent damages due to a short circuit or emergency
Cut down power when Vehicle in idle: if the vehicle is powered on, and the controller does not receive signals from the throttle for a delay, it will cut off the power supply to save energy. User can switch off and on to resume power supply.

2.2 Schematic of the basic circuit

This schematic shows the basic circuit to control a BLDC motor with speed regulation. The pins without any connection keep floating. To enable the function, user just need to close the switch or push the button. The completed electric system should include the DC/DC converter, speedometer and other devices from our Company.
2.3 Software Update and Parameter settings
Our company’s official website provides software download for controller‘s software update and software user manual. Please read the user manual carefully before change the parameters of the Controller. Before sending the controller to our customers, the controllers have already been fully test and own the latest version software.
When computer is online with the controller via USB and run the software provided by our company, the controller is ready for reprogramming to update firmware or change settings for new application. This operation should only be done by experienced engineers. Any wrong programming or setting may result in error or damage the controller.
The following picture shows a screenshot of our software .Users can use the software to set up the following three types of parameters:
1. The controller’s input parameters. Customers can modify the threshold and the maximum effective value of accelerator pedal.
2. Controller protection Settings. Customers can set Under voltage value, Over voltage value, Over temperature value, Over-temperature reliving value, Over current value and standby state power automatic shut down delay time.
3. Speed value and current limit Settings. Customers can set the max speed of economic mode and BOOST mode. And can set the bus current limit value of the two modes to save battery power.
Note: Calibration has already been done on the controllers before they sent to the customers; if customers have the change requirements please contact our company’s engineers. Customers are only allowed to modify the above parameters and not allowed to modify the other parameters for security concerns.
