High-isolation voltage, current, and power sensors are widely used in smart grids, because only by sensing these basic information can the grid be intelligently controlled. However, at present, these sensors are Hall-sensitive + processing circuit + shell + connector of the traditional way, failed to integrate, bulky, production commissioning and calibration workload, high cost.
The Hall current sensor in the magnetic sensor is widely used in brushless motors, ranging from small cooling fans in CPUs to medium-power brushless motors in electric bicycles. In addition, Hall sensors are also used for the torque sensor of the speed control switch on an electric vehicle.
In the field of brushless motors, the use of Hall sensors in motor commutation is currently the mainstream. For example, in the automotive, aerospace, industrial, agricultural machinery, control, military, and other fields, as long as the brushless motor is used, Hall is needed. Sensors are larger in the field of electric bicycles. In addition, micro-power Hall ICs are also used on flip phones.
Magnetic sensors want to develop. First, we must improve the sensitivity, stability under adverse conditions, reduce the operating voltage, and micro power consumption; secondly, the sensitive components and their processing circuits must be integrated and miniaturized; the third must be diversified in functions and sensitive to the same sensitive mechanism. , reference and integration of related mature technologies in other branches of electronic technology, which can form new varieties of new functions or composite functions; finally, to facilitate networking, the information captured by sensors is easy to interface with the upper and lower machines and wired or wireless transmission. Profit execution, preservation, processing.
Magnetic sensors include Hall-effect ICs, Wiegand sensors, metal-film magnetoresistive resistors, and indium-telluride magneto-resistive resistors, among which Hall-effect ICs are switch-type, latch-type, linear-type, etc., and are widely used in civilian applications. , industrial, control, military, aerospace and other fields, such sensors in our company our company Nanjing Qihu Technology Co., Ltd. is the originator.
The lithium ion cells can be either cylindrical batteries that look almost identical to AA cells, or they can be prismatic, which means they are square or rectangular The computer, which comprises: One or more temperature sensors to monitor the battery temperature. Lithium batteries are used in a wide variety of applications, including flashlights, vapes, EVs (electric vehicles), ebikes (electric bike), RC cars, Drones / Quadcopters / Multi-rotors, aerial photography, solar power systems, electric motorcycles, electric dirt bikes, electric car conversions,and so on.
Lithium 18650 cells are capable of delivering very high power due to its use of patented GLIDA battery technology. Based on lithium iron phosphate chemistry (LiFePO4), the cells are inherently safe over a wide range of temperatures and conditions.
