6 FAQs about [Power battery management chip principle]

How does a battery management chip work?

The state of the battery management chip determines the level of the output terminals, CO and DO, controlling the power switches. Both switches are turned on in the normal state. When the battery is in an overcharge or overcurrent state during charging, switch NM2 must be turned off to prevent the charging of the battery.

What is battery management system?

The battery management system is mostly equipped with the corresponding database management system of battery operation and charging data to evaluate the battery performance. The data support is provided by the optimal design of batteries for application to the market.

What is a battery management system (BMS)?

A Battery Management System (BMS) is an electronic system that manages and monitors the charging and discharging of rechargeable batteries. A given BMS has many different objectives such as I/V (current/voltage) monitoring, cell balancing, temperature monitoring, over-current protection, short circuit protection, etc.

What are the components of a battery management chip?

The chip mainly includes a bandgap reference, overvoltage detection (OVD) and undervoltage detection (UVD) circuits, discharging and charging overcurrent detection (COCD) circuits, an oscillator, and a timing circuit. Fig. 2. Diagram of a traditional battery management chip.

How much power does a battery management chip consume?

Fig. 14 illustrates a summary of the power consumption of the battery management chip. The battery management chip consumes 0.838 μA of quiescent current, and its power down current is less than 10 nA. The two current detection circuits and bandgap circuits consume almost more than half of the power.
