Embodiment 1

[0033] The multi-cell lithium battery balanced repair method based on the characteristics of LED lights in the present invention includes a lithium battery 2, and the lithium battery 2 is used for a power unit of an electric vehicle, and also includes the following repair method:

[0034] S1. Take out the lithium battery 2; control the discharge of the power source of the lithium battery 2 of the power unit through the BMS system carried by the electric vehicle, and take out the lithium battery 2 after the lithium battery 2 is discharged to the cut-off voltage;

[0035] S2, the sorting signal line 3; the signal line 3 connected to the lithium battery 2 is sorted out from the lithium battery 2 for backup;

[0036] S3. Connect the balance repair tool 1; the balance repair tool 1 includes a socket 4, and the socket 4 includes a socket, and each group of signal lines 3 in the S2 is sequentially connected to the socket from low voltage to high voltage, and the socket Connect the eq...

Embodiment 2

[0041]In this embodiment, the following further limitations are made on the basis of Embodiment 1: in the S3, the number of sockets of the socket 4 is at least 20. In the power unit of a conventional electric vehicle, there are 7-20 signal lines 3 of the lithium battery 2, that is, usually 7-20 lithium batteries 2 are connected in series to form a lithium battery 2 group to provide power, so at least 20 power strips 4 need to be provided. The socket can meet the purpose of connecting the conventional lithium battery 2 into the equalization repair tool 1. The equalization circuit includes an equalizer 6 formed by connecting at least one LED lamp 61 in parallel, or at least one LED lamp 61 connected in series with a resistor 62 and then connected in parallel. The equalizer 6 and a single lithium battery 2 are connected in parallel to form an equalizer circuit. If a single LED lamp 61 is not enough to balance the single-cell lithium battery 2 , then parallel connection can be use...

Abstract

The invention discloses a multi-section lithium battery equalization repairing method based on an LED lamp characteristic and relates to the lithium battery equalization repairing field. Lithium batteries are included. The lithium batteries are used as the power unit of an electric traffic tool. The repairing method comprises the following steps of S1, taking out the lithium batteries; S2, sortingsignal lines; S3, connecting to an equalization repairing tool; S4, executing an equalization voltage repairing; and S5, restoring the lithium batteries. In the invention, the complicated control ofa switch and an integrated circuit is avoided, an entire equalization processing process becomes easier and the same equalization lithium battery effect is achieved. Through arranging an alarm, a current voltage value can be visually seen and a buzzing sound can be used to prompt that equalization repairing is completed. And the cost of an equalization repairing tool is effectively reduced.

Description

technical field [0001] The invention relates to the field of balanced repair of lithium batteries, in particular to a method for balanced repair of multi-cell lithium batteries based on the characteristics of LED lamps. Background technique [0002] With the development of electric vehicles, the use of lithium batteries as the power unit of electric vehicles has been adopted by more and more enterprises. Since the power provided by a single lithium battery is limited, it is necessary to connect multiple lithium batteries in series to form a lithium battery pack. However, during the use of the lithium battery pack, due to the inconsistent production quality of the single lithium battery, it is prone to the problem of different loss speeds. Therefore, an equalizing circuit is needed to equalize the voltage of the lithium battery pack to achieve the purpose of extending the service life. In the prior art, the load consumption type balance and the fit capacitance method are usu...
