Battery management system (BMS) is a technology used to manage and protect the entire system of rechargeable battery. BQ2019PW is a programmable 4-cell battery monitor with integrated protection circuits and supporting a wide range of batteries. BQ2019PW can monitor battery temperature, voltage and other parameters, and can also carry out battery protection and balance control operations. In addition, it also can communicate with the battery charger, fuel gauge, and host processor for effective charging and discharging operations.
Application fieldBQ2019PW can be widely used in a variety of applications, such as mobile and laptop computer batteries, power tool batteries, electric vehicle batteries and medical batteries. And many related and upgraded product applications. The BQ2019PW is a fully-programmable battery monitor and system monitor and provides a wide range of configurable safety, safety and status management functions.
Working principleThe BQ2019PW combines analog to digital conversion, high speed I2C (I2C) communication, and system protection and control functions into a single chip. It can monitor various parameters of each battery, including voltage, current, temperature, up to 24V maximum system voltage and self-adjustment charging and discharging. The device operates with three outputs: SOC, VOVP, and SFOC.
SOC is the abbreviated term for State of Charge. SOC indicates the battery\'s current charge level and indicating the exact percentage from 0-100%. VOVP stands for Voltage Over Voltage Protection and SFOC stands for Short-circuit and Over-Current Protection, which supply the battery with some level of protection.
The BQ2019PW conducts a safety assessment of the entire system within the under and over-voltage charging condition, making sure that the load doesn\'t exceed the maximum batter capacity. It also implements protection against over-charging, over-discharging, over-current and short-circuit. It can detect the temperature of each battery, provides error status and uses the I2C interface to communicate with host micro-processor.
The BQ2019PW can also sense the remaining battery capacity (SOC indicator) in real time and can measure cell voltage accurately up to 0.05V resolution. Once the battery is determined to be overcharged or over-voltage, it will send an alert signal to the host and provide corresponding warning information. In addition, it also has the functions of over-temperature short-circuit protection, cell difference temperature compensation and optimization of charging load management.
ConclusionBQ2019PW is a versatile, powerful battery monitor and protection device. Its application field includes most of the popular types of rechargeable batteries, such as laptops, mobile phones, power tools, electric vehicles, etc. The BQ2019PW not only accurately measures the voltage, temperature and current of each battery but also can effectively protect the battery. It also provides SOC, VOVP, and SFOC monitoring and protection features. The features of BQ2019PW will only amplify in the future as new technologies emerge such as wireless charging, advanced battery materials and others.
