Abstract
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 ...
Examples
Embodiment Construction
[0008] Specific embodiments of the present invention are described with reference to the above drawings.
[0009] Depend on figure 1 It can be seen from the figure that this car backup charging power supply with power display includes a battery 10, a charging circuit 20 connected to the battery 10, and an output terminal 30 output by the charging circuit 20. The backup charging power supply also includes a measurement module 40 and a power display module 50. , the measurement module 40 is connected between the charging circuit 20 and the output terminal 30, the power display module 50 is connected to the measurement circuit 40, and the display module 50 is a liquid crystal display. In the present invention, the charging current and voltage are measured by the measurement module, and parameters such as the charging power, the power of the battery to be charged, or the existing power of the backup power supply are calculated by the MCU in the measurement module, and are intuitiv...
