This utility model patent discloses a low-power temperature acquisition circuit, comprising: a main microcontroller and a first auxiliary microcontroller. The first auxiliary microcontroller is connected to the main microcontroller via a bidirectional data line for data communication. The first auxiliary microcontroller includes a first power supply pin, a first ground pin, a first pin, and at least one first cascade pin. The main microcontroller is connected to the power supply pin via the bidirectional data line to supply power to the first auxiliary microcontroller. The first ground pin is grounded. The first pin is connected to a first thermistor. The first cascade pin is used to connect to a thermistor on a cascaded device of the first auxiliary microcontroller, or to connect to a microcontroller on a cascaded device of the first auxiliary microcontroller. This utility model also discloses a charge / discharge gun using the above-described low-power acquisition circuit to achieve multi-channel cascading with a single read, reducing communication transmission and lowering costs.
