The invention discloses a method for detecting charging voltage of a battery pack. The method is used for calibrating a voltage display numerical value of a charger, and comprises the following steps: firstly, calculating a full-power reference digital quantity V1 converted by an AD module when the battery pack is in a full-voltage threshold Vbat state by an operation module; secondly, calculating a full-power reference analog quantity V2 corresponding to each full-power reference digital quantity by an operation module; then enabling the AD module to collect a voltage real-time digital quantity V3; and finally, enabling the operation module to calculate a real-time voltage coefficient value V4 of charging of the battery pack, and displaying the real-time voltage coefficient value V4 on the display screen. An existing controller algorithm structure is changed, the real-time digital quantity V3 converted by the AD module is further calibrated through an algorithm formula in the operation module and converted into the real-time voltage coefficient value V4, then the value is displayed on the display screen, the real-time voltage coefficient value V4 can reflect the charging electric quantity of a current battery pack more visually and clearly, the real-time voltage coefficient value V4 can also reflect the charging electric quantity of the current battery pack more visually and clearly, and the voltage value of the battery pack is amplified by 100 times, so that the voltage display precision is further improved.
