At the 2012 Northern China International Lithium Electric Vehicle and Supporting Exhibition Conference held in Tianjin recently, the smart sensor technology exhibited by Sichuan Kuanhe Technology Co., Ltd. received widespread attention. Many industry insiders believe that intelligent sensing technology is an effective way to solve the current bottleneck in the development of lithium electric vehicles.
"Electric bicycles are used as leisure tools abroad, while Chinese users are used as real vehicles, and they even have to bear heavy loads. The utilization rate is extremely high." Chengdu Kuan and related officials told reporters that in the Chinese market, the sensor's Reliability and intelligence are more practical.
According to China's national standard for electric bicycles, the weight of electric bicycles should not exceed 40 kg, but this standard faces the problem of "difficult implementation" in the industry. According to analysis, the weight loss of the whole vehicle mainly depends on reducing the battery capacity, but this will lead to insufficient endurance of the whole vehicle. If a lighter and more environmentally friendly lithium battery is used, although the weight of the vehicle can reach the national standard, the existing electric bicycles generally use the handlebar control discharge method, which will greatly reduce the life and actual use capacity of the lithium battery. In this context, smart sensor technology has become the key to industry research and competition.
It is understood that Chengdu Kuanhe has spent 5 years collecting a lot of data on the riding comfort and system power saving effect of electric bicycle riders under different road conditions, so as to establish a mathematical model, use professional chips for intelligent processing, and develop intelligent hybrid power. Sensor system. It can perform intelligent digital processing by collecting physical quantities such as the real-time speed and instantaneous acceleration of the foot pedal, detecting the road surface gradient and road surface resistance during dynamic operation, and generating a pre-judgment result, and then the motor outputs appropriate power. This technology improves rider comfort, reduces motor wear, and also greatly improves the range and service life of lithium batteries.
