The relevant system to convert electric energy into kinetic energy is the focus of the design and development of new energy vehicles, which directly affects the vehicle efficiency and driving experience. The electric energy system of new energy vehicles needs to operate efficiently in extreme situations, such as the control of high current induction motor,   Solenoids and other drive components cause voltage transients and losses in power systems during critical operation.
In order to keep the performance of automotive electronic system in critical task, the ECU must be thoroughly tested. Battery array development and maintenance is a daily challenge for design and test engineers of new energy vehicles. Battery capacity and its quality state are inevitably related to safety, so charging pile and battery array test solutions are necessary and important.

The battery pack is usually composed of several single cells in series, and the internal resistance of the battery is an important factor affecting the charge discharge balance of the battery in series. Therefore, the production of the battery pack needs to detect the internal resistance of the single battery first, and match them consistently to ensure the best performance of the battery pack as a whole.
In the actual use of the battery pack, we need to regularly detect the working state of the battery pack to ensure the normal operation of the system. At this time, we need to use the battery internal resistance tester which supports online testing. It can quickly and accurately obtain the dynamic change of the internal resistance of a single battery, so as to judge whether the battery is ineffective.

The internet of things changes everything. Future IoT applications that require global coverage and mobility will focus on cellular technologies, such as 4G-based LTE-M and NB-IoT technologies, as well as future 5G technologies. Other applications will rely on low-power WAN technologies in unlicensed bands, such as Sigfox or LoRaWAN. Most applications will use short-range or medium-range wireless technologies, such as Bluetooth ®, WLAN/Wi-Fi, Zigbee, Z-Wave, RFID and Near-Field Communication, Optical tags and quick response codes, and Thread technologies. Smart devices today bring a new level of complexity in design, test, performance monitoring, and security.
