Advancements in Controller Development: Introducing the HA2 Model and Key Considerations
Hello to all ORDOOSPEED users!
Our team will be sharing the latest updates on controller development here. We warmly welcome professionals like you to provide us with your requirements and ideas, so that we can make our products more tailored to the market.
The white controller shown in the above image is our new controller model, HA2, which we are currently developing. Here is a preliminary outline of the specifications for this controller:
During the development process, there are several key considerations that we need to take into account. For example, whether to develop a universal or specialized controller, whether it should be compatible with all instrument models on the market, whether the size meets the requirements of electric scooters in the market, and whether the parameters meet the needs of the majority of consumers. Here are a few key factors we are currently contemplating:
Wireless Controller: Since the development of the CC1/CB1/HE1 models, we have been aiming to move towards wireless controllers. Last year, we released a 2-in-1 controller (GA1) that reduced the number of wires, but it still required signal and Hall wires to be connected externally (electric scooter models using this GA1 controller have recently been launched in the United States). With the latest HA2 model, we have achieved a truly wireless controller.

Waterproof Controller: We are not inclined to use potting for waterproofing as it significantly increases costs and makes it difficult to identify and repair faults in the controller. Instead, we plan to make the controller housing waterproof. However, the question arises as to whether such a housing can truly achieve waterproofing. And also here is another question: is it necessary for the controller to have an IP67 or IP65 rating?
Phase Wire: Typically, wireless controllers use locking screws for phase wire outlets. However, for electric scooter controllers, space is limited. We are currently planning to use copper heads for the wire outlets, but we have not yet achieved the desired small size. We are looking for a solution that is smaller in size and meets the current requirements of Continuous Current 120Arms, Continuous time 10s-30s, PEAK -170Arms to +170Arms, temperature would reach 50℃.
Signal Wires: We have reserved the following signal outlets:
These signal outlets are designed to be compatible with all vehicle scenarios. If we can reduce some of these outlets, it would help to further reduce the size of the controller.
Advanced Controller Applications: We are incorporating more professional communication protocols into the controller. We plan to use CANBUS. We are also researching industry opinions on other communication protocols such as UART, THROTTLE, and 485
These are the recent updates we wanted to share. If you have any interesting ideas or suggestions, please feel free to leave a comment and communicate with us. Of course, for those who engage in effective communication with our team, we will provide free samples of our new products.
