Problems solved by technology

It is precisely because battery repair has relatively strict requirements on technology, generally speaking, the overall repair effect of the current lead-acid battery is not ideal, and the repair efficiency is very low
For the above reasons, there is still a lack of equipment that can automatically and efficiently complete the repair of lead-acid batteries in the prior art

Embodiment 1

[0108] In one embodiment, reconditioning is to be implemented for 6DZM12 lead storage batteries used in electric bicycles.

[0109] This embodiment includes a database 1, a charging and discharging control device 7, a discharging device 2, and a charging device 3; wherein the charging device 3 and the discharging device 2 are respectively connected to the positive and negative ends of the external storage battery 6 to be repaired, and the charging device 3 and the discharging device are connected to each other. The device 2 is also connected to the charge and discharge control device 7 respectively, and the control device 7 is connected to the database 1 through a data line; the discharge device 2 discharges the storage battery 6 according to the instructions issued by the charge and discharge control device 7, and Return the corresponding data to the charging and discharging device 7

[0110] According to the conditions marked by 6DZM12 (12V12Ah, 2h discharge rate, standard d...

Embodiment 2

[0115] In another embodiment, the 6DZM12 special storage battery described in embodiment 1 is also remotely repaired. Optimize charging method. Specifically, the charge-discharge control device 7 selects the optimized level 5-step "quasi-two-charge-one-discharge" charging method stored in the database 1 at the 16th minute after the 6DZM12 battery completes the deep discharge, and the data related to the charging method includes: 2.0A Charging for 6h, 1.2A charging for 8h, 1.2A discharging for 2h, 1.2A charging for 8h, and 0.6A charging for 8h, the total remaining charging capacity is 33.6Ah, which takes 32h. attached Figure 7 In order to repair the charging I / T curve related to this embodiment, after the 5-step "quasi-two charging and one discharging" method is used to charge the battery 6 with 33.6Ah of electricity, the 6A discharge capacity can generally reach the technical expectation of the nominal 12Ah at one time Effect.

[0116] On the basis of Embodiment 1, this em...

Embodiment 3

[0118] In view of the need to increase the charging capacity of the storage battery in winter in northern regions, in another embodiment, when repairing the storage battery described in Embodiment 1, it is necessary to strengthen the charging capacity for repairing. When repairing the battery, the deep discharge process remains unchanged, but when charging, the parameter m set for calculating the charging capacity is 1.3, and the repairing charging capacity of the 6DZM12 battery during intensive charging in winter in the northern region is: C ( Ah)=﹢m﹢n(T 标称额定 -T 0 ) / T 标称额定 ﹞C 标称 =﹝1.3﹢3.0(120-56.6) / 120﹞C 标称 =2.885C 标称 , to deliver C=2.9C to the charging device 3 标称 (Ah) = 2.886 × 12Ah = 34.63Ah charging capacity repair method.

[0119] At the 16th minute after the 6DZM12 battery completes the deep discharge, the charging and discharging control device 7 automatically selects the eight-stage "quasi three charging and two discharging" charging method stored in the databas...

Abstract

The invention relates to a storage battery restoration system. The system comprises a database, a charge-discharge control device, a discharging device and a charging device. Externals of the charging device and the discharging device are connected to a storage battery to be restored, and internals of the charging device and the discharging device are separately connected to the charge-discharge control device. The charge-discharge control device is connected to the database device through a data line. A storage battery restoration method provided by the invention can select a restoration manner of determining a charging amount and a charging procedure according to actual discharging data of different storage batteries, thus improving restoration effects of the storage batteries effectively.

Description

technical field [0001] The invention relates to the field of storage batteries, in particular to a storage battery repair system and a repair method thereof. Background technique [0002] Batteries are generally referred to as batteries that can be repeatedly charged and discharged, also known as secondary batteries. Currently, lead-acid batteries are the most widely used storage batteries in the market. They have a wide range of sources of manufacturing materials, low prices, and have the advantages of safety, reliability, large capacity, and high discharge intensity. Among the various types of batteries currently in use, only lead-acid batteries can achieve a recycling efficiency of 99%, and material resources can be recycled almost completely, which is in line with the development trend of green and environmental protection. At present, lead-acid batteries occupy an absolute dominant position in high-power / large-capacity fields such as electric tractors, vehicle and ship...
