Battery power extension device and battery power extension method

Abstract

The battery power extension device of the present invention includes a switch device and a processing circuit. When the processing circuit is in the starting mode, the switching device is controlled so that the fast energy storage module is connected in parallel to the battery; when the charging mode is entered according to the trigger signal, the switching device is controlled so that the fast energy storage module is disconnected from the parallel connection with the battery. When the battery power supply system stops running, a trigger signal is generated to charge the fast energy storage module, so that when the battery power supply system starts, the fast energy storage module with sufficient power is connected in parallel as an auxiliary, and the battery itself is reduced when it is started. Electric energy, thereby prolonging the service life of the battery, and enabling the battery to achieve normal start-up function in a state of low electric energy, so that the electric energy of the battery can be really used up. With battery performance detection, users can safely use up all the available power of the battery.

Description

Technical field [0001] The present invention relates to the field of battery power supply systems, in particular to a battery power continuation device and a battery power continuation method. Background technique [0002] At present, if the vehicle is under-voltage (the starting battery is dead), the vehicle cannot be started by the original starting system. Therefore, the starting system needs to be jump start. The jump start is performed on the battery of the starting system. The two electrode ends are connected in parallel with another battery, so that the starting device has enough voltage to trigger. [0003] This jump start method is not only troublesome, but may also be dangerous due to the wrong connection of the battery electrodes. [0004] Furthermore, any electronic device on the vehicle that requires a battery will cause the voltage of the battery to drop instantaneously at the moment it is started. Therefore, how to stabilize the battery voltage to extend the life of t...

Problems solved by technology

However, in this vehicle starting power supply, when the battery power is insufficient, the controlled switch is used to disconnect the connection between the battery and the system and the parallel connection between the battery and the capacitor, so as to retain the power of the battery, and the second start signal When it is generated, the controlled switch is closed and the battery uses the remaining power to charge the supercapacitor; there will be a battery pack that takes on the double load of starting and charging the supercapacitor at the same time, which will intensify the battery load and accelerate the degradation, or The problem of not having enough power to start and charge the super capacitor at the same time
