New energy vehicles, especially electric vehicles still face security risks, short mileage, system architecture, lack of reliability, product quality uneven, high cost, charging difficult problems. Among them, the most important challenge is the safety and reliability of the system, after all, for the development of the market and consumers, whether it is forward-looking technology, more attractive preferential policies, 'security Kaopu' is the Sensor most critical and most basic Guarantee. In addition to the battery, motor, electronic control and other key technologies to achieve a breakthrough, including connectors, sensors, contactors, relays and other core components of the field should also make a difference; even these original in the traditional automotive field 'Supporting role' With the comprehensive improvement of electronic and electrical architecture, the increasing number of applications, the entire system architecture presented by the reliability, the perfect play a key supporting role.

To electric vehicle system architecture, for example, by the battery, drive motor and electronic control, high voltage distribution box, charging system, high voltage auxiliary electrical components of several components. Whether it is from the component itself or the entire system architecture, are related to the connection, sensing and protection, and the connection and sensing is the benchmark, through the connection, the sensor to achieve protection. However, compared with traditional cars, high voltage and high current system architecture, these core components are facing more stringent requirements and challenges.
The new electrical system architecture requires not only the handling Suction Control Valve of very high continuous currents, but also the overload current, for the main contactor that connects and disconnects the power battery from the inverter. Safe breaking. Once the battery is short-circuited, these contactors must be able to carry thousands of amperes of current until the main fuse cuts off the circuit.

The future of pure electric vehicle sensor development trend is to achieve miniaturization, multi-functional, integrated and intelligent. This requires the sensor not only has a small size, cheap, high reliability, but also in precision, functionality, intelligence and other aspects to be improved again. There are circuit protection, manual maintenance switches, relays, wiring harness and other basic components, in the new electrical architecture also to be upgraded. However, for the OEM, the innovation of a single component is important, but its more important is the stability of the system, reliability, is also more 'Kaopu' system of solutions. As the core of the new energy vehicles and power source, the battery pack is not only from the major, and the structure is more complex, it consists of multiple batteries module, each module has a few to a dozen unequal power Core composition. Among them, between the module, between the batteries and the management of batteries within the battery management system (BMS) within the Fuel Rail Pressure Sensor current transmission and signal transmission requires a variety of connections and current and temperature monitoring, and the battery external transmission to have high-voltage connector The Therefore, the reliability of battery connection and module connection, high and low voltage interface, current and temperature monitoring is very important.
