This paper describes a stackable battery monitoring and management integrated circuit for EVs. Owing to the number of cells in the series, the amount of data transmitted by the BMS is significant. The integration of digital control and registers in the BMIC is necessary for the efficient execution of each function.
In addition, the digital modules integrated into the chip support function control, data storage, fault reporting, and so on. These features make the application of the proposed chip more comprehensive, and suitable for high-power battery management solutions such as EVs and energy storage.
The key to ensuring the performance and reliability of energy vehicles is the BMS, in which BMIC is responsible for accurately monitoring various battery cell data. A 16-cell stackable battery monitoring and management chip using 0.18 μm high-voltage BCD technology was designed in this study.
A high-efficiency radio frequency (RF) energy–harvesting chip was designed and fabricated. With an off-chip antenna and rectifier, the system scavenges ambient RF energy and converts it into usable energy, which is then stored in energy storage elements (such as a supercapacitor or a rechargeable battery).
A 16-cell stackable battery monitoring and management chip using 0.18 μm high-voltage BCD technology was designed in this study. The proposed dual-output high-voltage regulators can directly power each module in the chip with high-voltage input and low quiescent current.
The chip performs two different data conversions in one monitoring instance, and the measurement error of the 16 channels is controlled within ±4 mV during calibration. The power management unit in the chip provides a stable internal module power supply voltage at an input voltage of 80 V, and the quiescent current is lower than 16 μA.
