Battery power continuing device and battery power continuing method

Abstract

The invention discloses a battery power continuing device which comprises a switch device and a processing circuit. When the processing circuit is in the starting mode, the switch device is controlledto enable a fast energy storage module to be connected with a battery in parallel. When a charging mode is entered according to triggering signals, the switching device is controlled to enable disconnection of the parallel connection between the rapid energy storage module and the battery. When a 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is generated to charge the fast energy storage module, so that when the battery power supply system is started, the withdrawn electric energy of the battery when the battery is started is reduced due to the fact that the fast energy storagemodule connected in parallel with enough electric quantity is used as the auxiliary, and the service life of the battery is prolonged. When the battery is in a low electric energy state, the normal starting function can still be achieved, and the electric energy of the battery can be really used up. By means of the battery performance detection, the user can more safely use all available electricenergy of the battery.

Description

technical field [0001] The 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 perform a jump start. Connect another battery in parallel to the two electrodes so that the starting device has enough voltage to trigger. [0003] This jump starting method is not only cumbersome, but also dangerous because the electrodes of the battery are connected incorrectly. [0004] Furthermore, any electronic device that needs to use the battery on the vehicle will cause the voltage of the battery to drop instantly when it is started. Therefore, how to stabilize the voltage of the battery to prolong the life of the electronic device and ignition system, and how to increase the li...

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
