A current control unit, power supply device and vehicle

Abstract

The present invention provides a current control unit, a power supply device and a vehicle. The current control unit includes a power supply module, a control module, a diode module, an output port and an input port. The control module is used to obtain the first temperature information of the diode module, according to the first The temperature information controls the voltage drop of the diode module to adjust the output current of the power supply module, which is beneficial to control the output current of the internal power supply module when supplying power to the load, so as to reduce the impact on the service life and the life of the power supply module due to excessive output current. Adverse effects on security. The power supply device includes M above-mentioned current control units, and the M current control units are connected in parallel to charge the load. The structure of the power supply device is simple. A single device can use power supply modules of different types and different physical characteristics, and the device can realize the output of the internal power supply module at low cost. Current balance is beneficial to improve the service life, safety and reliability of the power supply device. The vehicle includes the power supply device.

Description

technical field [0001] The invention belongs to the field of electronics, and in particular relates to a current control unit, a power supply device and a vehicle. Background technique [0002] With the continuous change of lithium battery technology, the cost of lithium batteries is gradually reduced, and its application fields are becoming more and more extensive. In the application of lithium batteries in various scenarios, parallel use is a common phenomenon. Through the parallel connection of lithium batteries, battery packs with various capacities for different applications can be designed. Under normal circumstances, there will be no problem in the parallel use of lithium battery packs of the same specification and performance, but when the parallel lithium battery packs come from different manufacturers, there are many hidden dangers in the parallel use of lithium battery packs, especially in When the lithium battery pack is discharged, the output current of differ...

AI Technical Summary

Problems solved by technology

This method consumes a lot of manpower and material resources, and, with the increase of the service time of lithium battery packs, it is difficult to keep consistent changes in the physical characteristics of different lithium battery packs

At the same time, this approach cannot effectively solve the problem of reusing decommissioned lithium batteries on new energy vehicles
