Abstract

The invention discloses a method for detecting a battery and a standby charging power supply on a vehicle, and the standby charging power supply. The standby charging power supply comprises the battery (10), a charging circuit (20), an output end (30), a measuring module (40) connected between the charging circuit (20) and the output end (30) and an electric quantity display module (50) connected with the measuring module (40), wherein the measuring module (40) outputs four paths of signals to the electric quantity display module (50) through a multi-path option switch (60). By adopting the technical scheme, the standby power supply can display a series of parameters, such as a charging electric quantity and the like, so that a user can master the conditions of the standby power supply and the charged battery conveniently, charge or replace the battery timely and the like.

Description

technical field [0001] The invention relates to automobile supplies, in particular to a backup power supply for charging automobile batteries. Background technique [0002] The backup power supply in the prior art is generally just for charging. How much electricity has been charged, the charging power supply and the electric quantity of the battery to be charged are unknown, and it is easy to cause the backup power supply to fail to replenish electric energy in time, and cannot be used due to lack of power. In addition, this kind of battery does not know the state of the battery to be charged, and cannot judge the performance and life of the battery to be charged, which brings inconvenience to the user. Contents of the invention [0003] The invention provides a method for detecting the battery on the vehicle and a backup charging power source and the backup charging power source, and uses a display device to display the power, which solves the technical problem that the ...
