01 products of awarded medal

The DNB series of battery management chips ofr Datang NXP belongs to the single cell battery monitoring chip Category. It distinguishes itself as the sole Chinese company capable of providing a single-cell architecture. isthe only company in China that can provide a single cell architecture,

During the battery production phase, this series meets the criterion of embedding a single AFE chip within each battery, efficiently capturing a comprehensive array of battery-related parameters and unique information, encompassing battery chemical composition and manufacturing details.

Achieve comprehensive health management across the entire battery lifecycle, encompassing voltage, temperature, and carbon footprint tracking. Additionally, utilize unique electrochemical impedance spectroscopy detection technology to detect and document battery characteristics.

02 Product Features

The AFE (Analog Front End) chip serves as the core value component of the BMS (Battery Management System), accounting for over 60% of its total value and posing the greatest design challenge. Especially as the market demands increasingly stringent safety standards for battery management, AFE chips that possess dual detection capabilities for both internal and external battery temperatures will significantly reduce the risk of thermal runaway, representing a substantial boon for new energy vehicles.

The DNB11 series AFE chip completely breaks this technological barrier, innovatively integrating impedance spectroscopy detection function into the chip, achieving dual detection of internal and external temperature of the battery for the first time in the world. It efficiently and multi-dimensional deeply manages the internal health of the power supply, and eliminates the risk of thermal runaway in the early stage, greatly improving the safety factor.

Product Performance

The integrated temperature sensor in the DNB11 series AFE chip can cover each cell with a coverage rate of 100%.

Innovative feature: Real time monitoring of cell impedance to reflect the internal temperature of the cell.

Dual temperature monitoring method [internal battery+ surface battery] ensures safety.

Fault monitoring response time: seconds. By estimating the internal temperature of the battery cell through internal resistance, it is possible to quickly determine whether there is a trend of thermal runaway in the battery cell, achieve  warning in advance, and avoid thermal runaway.

To enhance the accuracy of SOC (State of Charge) and SOX estimation, the functionality of electrochemical workstations, currently limited to laboratory conditions, can be integrated into battery packs. This integration would enable true SOH estimation based on the internal mechanism aging degree of the battery cells.

Battery passport, the chip can be embedded into the battery during the production stage, recording a series of battery related parameters and unique information such as electrochemical composition and manufacturing information, achieving health management and carbon footprint tracking throughout the battery's entire life cycle.
