    RFstar BG22A1 Bluetooth Module Empowers BMS Industry
    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. Solutions 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.

  • Energizing Health Care Appliances, The Bluetooth Massager Market Grows With the Trend
    Energizing Health Care Appliances, The Bluetooth Massager Market Grows With the Trend
    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. The following describes the way to replace the traditional wire control with Bluetooth remote control. The operation of the massager will become very convenient. 1.Remote control, convenient and efficient RF-star technology's Bluetooth remote control solution uses Bluetooth communication to replace the original wire control form, and directly connects with mobile phones or tablets and other platforms for Bluetooth wireless control. There is no need to design a handheld wired remote control. The design is simple and feasible. 1. Wireless control: Traditional massagers are mostly wired, which brings a lot of inconvenience to operation. 2. Various modes: The supporting APP can remotely control a variety of scene massage methods, and the experience is rich. 3. Promote the development of the industry: Smart massagers have always had a Bluetooth trend, and the addition of Bluetooth can promote the development of the industry. 2. Advantages of RF-star BLE Module RF-BM-BG22A1 1. Low cost: Imported chips, stable supply, aggressive price 2.
