Datang NXP-Battery Management Chip DNB1168 (applied in new energy vehicle BMS system)

Battery management chip DNB1168 (applied to new energy vehicle BMS system)

Product Description:

DNB1168 is a world-leading single-cell monitoring chip with integrated (EIS) AC impedance spectrum monitoring function. The chip has passed the dual certification of automotive-grade AEC-Q100 and ISO 26262:2018 ASIL-D, the highest functional safety level in the automotive industry. The chip integrates a variety of high-precision battery parameter monitoring, supports voltage, temperature, AC impedance detection, balancing and a variety of fault diagnosis functions, and can provide the battery with an exclusive battery online "CT" detection technology worth hundreds of thousands of dollars, providing a new detection dimension for the battery management system, and realizing health monitoring of the entire life cycle of the battery.

Unique advantages:

DNB1168 is innovative and disruptive. It is the only single-cell monitoring chip in the world that can integrate (EIS) AC impedance spectroscopy monitoring function. EIS detection technology is our company's unique patented technology.

Application scenarios:

This chip is mainly used in the new energy automotive and industrial energy storage market. It is aimed at battery manufacturers, automobile manufacturers, energy storage system integrators and other customer groups. Our company provides them with chips and application solutions. The product is an innovative functional product and has been put into large-scale commercial use.

Future prospects:

The core value device in BMS is the AFE chip, which accounts for more than 60% of the value of BMS. The AFE chip is also the most difficult to design, so our company takes the AFE chip as the basis and core, focusing on breaking through this core point to drive more peripheral devices. At present, our customer base has covered domestic and international customers, and a certain brand effect has been formed. This year, the number of customers has increased dramatically, and the increase rate of landing projects has exceeded 300%. As of now, tens of millions of orders have been achieved. Due to the novel functions of the chip, the EIS detection function can realize the internal health detection of the battery, which is of subversive and major breakthrough significance, and the application algorithm requires time to accumulate. The radiation of future products will surely be more extensive.
