Problems solved by technology
If a common charger is used to charge different batteries, it is easy to cause the battery to be damaged and the charger to be overloaded and burned
Therefore, the charger of this emergency power supply can only charge the internal battery, and cannot be used to charge the external battery.
This just makes the extensiveness and the convenience of the application of this kind of emergency power source be very limited.

The invention provides an emergency power supply with a charging machine, comprising a charging machine and an accumulator battery which are connected with each other in series. The charging machine comprises an input circuit, a charging control circuit, a detection circuit, an integration element control circuit and a charging current selection circuit, wherein, the integration element control circuit comprises a function IC used for controlling the running of the whole emergency power supply. The emergency power supply adopts high-frequency technique, integrates the function IC, carries outthe charging of the accumulator battery according to the charging characteristic during the charging of the accumulator battery, and ensures the battery not to be charged by over-current; the chargingmachine is not damaged due to over-current and can be also respectively used for charging the internal battery and the external battery. The emergency power supply has high efficiency, saves the energy, has convenient and safe usage and strong maneuverability, and is applicable for the accumulator battery with different charging voltages and different capacities.
Description
technical field [0001] The invention relates to an emergency power supply, in particular to an emergency power supply with a charger. Background technique [0002] The general emergency power supply is mainly composed of batteries, special chargers and relatively simple control circuits. Due to the different capacities and characteristics of batteries, ordinary chargers are often only suitable for charging a specific battery. If a common charger is used to charge different batteries, it is easy to cause the battery to be damaged and the charger to be overloaded and burned. Therefore, the charger of this emergency power supply can generally only charge the internal battery, and cannot be used to charge the external battery. This limits the wide application and convenience of this emergency power supply. Contents of the invention [0003] The object of the present invention is to provide an emergency power supply with an intelligent charger with wide application objects a...
