The rapid development of new energy vehicles arena bolsters exponential growth of the power battery industry, which further boosts the development of BMS technology. Power battery makers such as Sunwoda, BYD, Evebattery, and Neusoft Reach are increasingly prone to adding Bluetooth modules inside the BMS to achieve wireless BMS application. Replacing the traditional cabled packaging method,a BLE solution can dramatically reduce the size of the BMS system, and making it more secure, more reliable, and more affordable. Challenges for BMS Systems The traditional BMS technology are facing quite a few challenges.  Challenge 1: the traditional BMS adopts a space consuming wired architecture, it is not only costly in maintenance, but also difficult in meeting the demand for continuous real-time battery monitoring. Challenge 2: the traditional transmission method of the BMS is relatively high power consuming and weak in scalability. Challenge 3: the cost of the traditional BMS system is very high. The wire harness (often copper wire) and plug-in connectors will add extra weight and cost to the solution. And as it also requires manual assembly, it results in a high labor cost. BMS Solutions with Bluetooth Technology Facing the above challenges, mainstream manufacturers start to apply Bluetooth modules to BMS systems and develop wireless BMS technology. Bluetooth technology makes the BMS package much more compacted, less power consuming. And since it significantly reduces application of wires and saves the labor of wire assembly, it dramatically reduces the cost of the whole solution. By ensuring successfulinnovation of BMS makers with its excellent performance, RF-star’s RF-BM-BG22A1 Bluetooth module has gained high recognition in the automotive field. Followings are the unique advantages of the product: More Intelligent and More Flexible The BMS system requires no cable connection after adding the RF-star’s RF-BM-BG22A1 Bluetooth module. With embedded BLE modules, it can use wireless communication to track the status and performance of every single battery, transmit such data as voltage, current, etc. of the battery pack to the PDA in real-time. With support of such data and some precautious signals, the charging and discharging processes of the battery can be well managed. Moreover, it also reduces the complexity of the whole system, saving spaces and improving reliability of the BMS. More Affordable With Bluetooth modules embedded, the BMS solution shakes away from the hassle of  cables and tedious harnesses labor, saving significant assembly cost, and making it more align to the the current trend of lightweight design in the automotive industry. Based on Silicon Labs chip, RF-star’s RF-BM-BG22A1 based on EFR32BG22 chip is a low-energy Bluetooth module that supports Bluetooth 5.2. It has excellent low power consumption performance and strong anti-interference ability. The product has passed many authoritative certifications, such as Reach cert...

Indoor Positioning Automotive is surrounding our daily life. Everyone has the experience of parking cars in the underground parking. It is a big problem to find our car without direction at such sites. As the GPS/BeiDou/Galileo cannot work indoors, Beacon is the best choice for indoor positioning. It uses the RSSI to do the locating. The cheaper price and the various product forms make it easily deploy. AoA AoD has also energized the Beacon products, which achieves better positional accuracy. Use RF-star BLE module to do your Beacon product. We also support the OEM and ODM on the Beacon product.

With the growth of Chinese residents' per capita disposable income, medical and healthcare consumption, as well as the increase in health awareness, modern massage appliances with good health effects are gradually entering the Chinese family. Moreover, the expansion of the domestic sub-healthy population, middle-aged and elderly population, business travel and office population has ushered in a round of rapid growth in the massage and healthcare market. In the use of traditional massage products, the wired controller is widely used, which is cumbersome and inconvenient to operate. Moreover, in the actual use process, if the massage mode needs to be adjusted, the controller needs to be placed within the visual range. The cord also wastes space in the daily storage of the massager, and there is a potential safety hazard of tripping.
