Shop owner Wang of the electric vehicle repair shop's troubles: During the rainy season, the returned control boxes brought in for repair were mostly short-circuited due to rust on the circuit boards. With this 12-channel wireless controller from KEHUAN installed, it happened to be during a severe rainstorm. Thirty water delivery tricycles crossed through knee-deep water, and the controllers completed the tasks without any faults.
Core innovation breakthrough
Intelligent thermal management: Dual gradient cooling system (maintains core temperature of 65°C even at 50°C ambient temperature)
Dynamic wireless control: Communication range of 2.4G wireless protocol exceeds 300 meters
Composite waterproof structure: PCB triple protection coating + shell labyrinth sealing (reaches IP68 protection level)
Installation and debugging instructions
② Regularly clean the weeds on the heat sink (suggested to check every 500 kilometers)
④ In winter at temperatures below -20°C, activate the low-temperature mode
Verification of the logistics fleet in Chengdu
An express delivery three-wheeler with an average daily load capacity of 2 tons:
The failure rate of the controller has decreased from an average of 3.7 times per month to 0.2 times per month.
The single charging range has increased by 12% (with energy recovery efficiency reaching 18%).
The emergency braking response time has been shortened to 0.03 seconds.
Cross-border adaptation advantages
2.Electric delivery truck: Slope recognition automatically switches torque mode
3.Electric shuttle bus: Wireless group control synchronization error < 0.5 seconds
Technical Parameter Highlights
1. Voltage Resistance: DC 72V (Transient Overload Capacity: 96V/3s)
2. Communication Interface: Compatible with RS485/CAN/BLE 5.0
3. Vibration Test: Passed GB/T2423.10 15G acceleration verification
Seven Questions You Must Ask When Purchasing
Q: What is the actual performance of the waterproof feature?
A: It can still function normally when submerged in 1-meter-deep water for 72 hours (with SGS test report attached)
Q: How to protect the vehicle on continuous downhill slopes in mountainous areas?
A: Equipped with EBS electronic braking system and graphene energy dissipation module.
Q: Is it compatible with the older motors?
A: We offer an adaptive version of DC brushed/brushless motors.
Q: How is the anti-interference performance of the wireless signal?
A: It uses military-grade frequency hopping technology (with 50 channels automatically switching).
Q: Maintenance cycle?
A: Our unique self-diagnosis system displays fault codes along with the countdown timer for maintenance period.
A: It offers the function to switch between two-wheel and three-wheel modes.
Q: Adaptability to extreme temperatures?
A: Operating range of -40℃ to 85℃ (verified and certified by the Russian Polar Research Team)
Examples of People's Livelihood Projects
Case of the Transformation of the Beijing Hutong Garbage Collection Team: After 200 old vehicles were equipped with KEHUAN controllers, their climbing ability increased from 25° to 32°, and the battery range increased by 8 kilometers. The team leader joked: "Now collecting garbage is like playing a remote control car. We can operate it even through the wall of the hutong."
Hidden benefits
Financial accounting of the sanitation company: The annual maintenance cost for a single tricycle has decreased from 2,800 yuan to 450 yuan. An unexpected bonus is that the battery life has been extended by 30%. What surprises the safety management department even more is that the wireless control function has reduced the accident rate of human-vehicle contact by 64%.
Expand application scenarios
Tourist sightseeing vehicle operators unlock new skills: Through the mobile app, the fleet can be intelligently grouped. With just one person in charge, 15 electric shuttle vehicles can be operated. During rainy season when crossing water, the real-time water level monitoring function automatically raises the chassis height. Tourists jokingly call it "a cruiser in a tricycle".
