VOLTAGE MEASUREMENT CIRCUIT AND METHOD, CIRCUIT BOARD, AND CONTROL MODULE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18232839 titled 'VOLTAGE MEASUREMENT CIRCUIT AND METHOD, CIRCUIT BOARD, AND CONTROL MODULE
Simplified Explanation
The abstract describes a voltage measurement circuit designed to measure the voltage output of a battery consisting of multiple battery cells connected in series.
- The circuit includes multiple low-voltage measurement modules, each corresponding to a battery cell.
- It also includes a first switching circuit and a second switching circuit.
- A reference voltage source is used to output a preset reference voltage.
- The low-voltage measurement modules are connected to the battery cells and the reference voltage source through the switching circuits.
Original Abstract Submitted
A voltage measurement circuit for measuring a voltage output by a battery, the battery comprising n battery cells connected in series, wherein n is an integer greater than 1; and the circuit comprising: n low-voltage measurement modules provided in one-to-one correspondence with the n battery cells, a first switching circuit, a second switching circuit, a reference voltage source, and a control module, wherein the reference voltage source may be used for outputting a preset reference voltage; and the two ends of each of the low-voltage measurement modules may be connected to the two ends of a corresponding one of the battery cells via the first switching circuit, and the two ends of each of the low-voltage measurement modules may be further connected to the two ends of the reference voltage source via the second switching circuit.
