Problems solved by technology
[0002] As the power source of electric vehicles, the power battery supplies electricity to the vehicle by converting chemical energy into electrical energy. In the current power battery technology, if the battery capacity of the power battery is discharged below a cut-off voltage and continues to discharge, it will cause The damage of the power battery will affect the service life of the power battery. Therefore, the general power battery is equipped with a control system to monitor the operating status of the power battery to avoid damage to the power battery.

Embodiment Construction
[0026] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.
[0027] Such as figure 1 As shown, the present invention provides a multifunctional selective power supply system based on power battery packs, including the first to Nth power battery packs, the first to the first power battery packs for controlling whether the first to Nth power battery packs supply power The N control circuit, the interlocking switch group, and the controller, through the control of the interlocking switch group, realize that the first to Nth power battery packs sequentially supply power to the controller individually or in parallel. The first to Nth power battery packs are power battery packs with the same voltage, same / different capacity, and same / different chemical properties.
[0028] Such as image 3 As shown in the circuit on the left, the first control circuit includes a first solid state relay, a first relay, ...

The invention relates to a multifunctional selective power supply system based on a power battery pack. It includes the 1st to Nth second power battery packs, the 1st to Nth control circuits for controlling the power supply of the 1st to Nth power battery packs, the linkage switch group, and the controller. control to realize that the 1st to Nth power battery packs supply power to the controller individually or in parallel; the 1st to Nth power battery packs are of the same voltage, same / different capacity, and same / different chemical properties Power battery pack. The present invention takes the SSR as the core hardware circuit as the key point of operation, and solves the problem of power battery packs of the same type or non-electric battery packs, and the innovative point between different types of power battery packs or non-electric battery packs is based on the original life of the battery and normal use. The command cycle below is to complete the parallel power supply of battery packs, and the parallel power supply and sequential power supply with optional number of battery packs. The present invention can improve the stability and reliability of power supply.
Description
technical field [0001] The invention relates to a multifunctional selective power supply system based on a power battery pack Background technique [0002] As the power source of electric vehicles, the power battery supplies electricity to the vehicle by converting chemical energy into electrical energy. In the current power battery technology, if the battery capacity of the power battery is discharged below a cut-off voltage and continues to discharge, it will cause Damage to the power battery will affect the service life of the power battery. Therefore, a general power battery is equipped with a control system to monitor the operation status of the power battery to avoid damage to the power battery. Moreover, after the general electric vehicle leaves the factory, the power battery pack and the fixed battery cannot increase the capacity. If the implementation of this patent can adopt a fixed battery or a mobile battery, the capacity of the power battery can be easily expand...
