/PRZWT/At the recently successfully concluded 8th (Suzhou) Power Tool Control and Charging Technology Seminar, Ma Wenhua, Marketing Manager of Gewarte Technology, was invited to attend and gave a keynote speech on "Safe, Easy-to-Use, and Intelligent Cleaning Appliances BMS", providing an in-depth interpretation of relevant solutions.
JEWAT BMS products cover 3C products, small power batteries, automotive batteries and energy storage batteries and other application fields. It provides a full sequence of 3-8 series lithium battery BMS products for power tools and cleaning tools, and provides customers with a one-stop lithium battery BMS solution. Including: hardware protection chips for minimalist battery pack design, front-end chips for platform battery pack design, front-end/MCU two-in-one chips for high-integration battery pack design, secondary protection chips for safety certification, and charging management chips in battery packs.
Use "core" to empower, drive the development of the industry, and meet the diverse needs of customers.
3-26 string of large platforms to accelerate product iteration with the power of "compatibility"
With the intensification of market competition, major end point brands continue to accelerate the iteration speed of products, and fast and good BMS product design has become the core appeal of battery pack manufacturers.
In line with the trend, JEWAT has launched a new generation of acquisition front-end chips to build a 3-26 string software and hardware platform for customers with a serialized product portfolio. The series of chips under this platform are compatible with each other, and the number of strings covers 3-26 strings. Customers no longer need to develop software separately for battery packs of different strings, which can truly realize the better cost performance of "one set of software, multiple sets of BOM". The simple and easy-to-use platform can greatly reduce R & D and time costs, helping customers respond quickly to demand in the fierce market competition and seize the opportunity.
Exclusive application solution of wireless vacuum cleaner based on key product JW33508
JW33508 is a digital front-end chip specially designed for 3-8 strings of lithium battery packs, especially suitable for BMS design of wireless vacuum cleaners or washing machines. In addition, JW33M08, a product with built-in MCU, is suitable for 3-8 strings of highly integrated battery packs.
Triple advantages to enhance the core competitiveness of products
Safer: A number of protection functions to lower the risk. High-precision collection of voltage, current and temperature data to capture abnormal battery conditions, with over-voltage, over-current, short circuit and other protection mechanisms, disconnection detection function to detect battery connection problems in time, effectively reduce safety hazards, and escort the use of clean appliances.
Easier to use: high precision, fast response, easy to develop. In terms of accuracy and response speed, the JW33508 has excellent performance, the single sampling time of the fast current ADC is only 2mS, and the voltage/current ADC supports three simultaneous acquisition per second, which can achieve timely feedback on battery status. Compatibility Share software resources with other chips in the platform, no need to develop software separately.
More intelligent: flexible configuration, more accurate quantitative perception. With highly intelligent serial number configuration and detection functions, it helps customers grasp the connection between batteries and external devices in real time and optimize management logic.
Relying on the core advantages of "safety, ease of use, and intelligence", the new generation of platform-based BMS solutions and product matrices launched by Jewhart bring new ideas to the battery management technology upgrade of the clean appliance industry.
