Problems solved by technology

[0005] At this stage, some high-end instruments for battery failure diagnosis are popular in the market. The price is high, the diagnosis process is complicated, and the time-consuming is relatively long, so it is difficult to apply on a large scale. The electromotive force performance is obviously different, especially the failure mode of the power battery and energy storage battery used in the cycle system is mainly the capacity drop, and the no-load electromotive force performance of real-time discharge is closely related to the repair capacity. The repair rate of the

Embodiment 1

[0049] Design a discharge recorder specially used for 6DZM20 capacity restoration probability of electric bicycles. Among electric bicycles in the current market, electric bicycles using lead-acid batteries account for more than 80% of the market capacity, and 6DZM20 products account for the lead used in electric bicycles. More than 80% of the market capacity of acid batteries.

[0050] The discharge recorder includes a discharger 1, an electric control switch 2, a control module 3, a data display table 4, a casing 5, a power terminal 6 and a data terminal 8, wherein the power terminal and the data terminal are set as dedicated interfaces, which are fixed on the casing. The operation panel of the electric control switch; the discharger is electrically connected to one end of the electric control switch, and the other end of the electric control switch is electrically connected to the power supply end; a control program is stored in the control module, and its control end is con...

Embodiment 2

[0057] On the basis of Embodiment 1, the power supply terminal 6 and the data terminal 8 fixed on the operation panel of the housing 5 are designed as two-in-one dedicated interfaces with integrated appearance, and correspondingly designed power cords and data cords are configured.

[0058] In addition, a manual switch 7 is added on the basis of Embodiment 1. The manual switch is fixed on the operation panel of the housing 5, and the other end of the electronic control switch 2 and the power supply end 6 are electrically connected in series internally, as shown in Image 6 As shown; setting the manual switch can reduce the use of misuse, before starting the manual switch, it should be checked that all connections of the external circuits are correct.

[0059] This embodiment and the previous examples can be equipped with a heat dissipation device including an electric fan and a heat sink; the material of the heat sink is aluminum alloy, the shape is multi-row fins, and the heat...

Embodiment 3

[0061] On the basis of the hardware logic structure and control relationship of Example 2, a discharge recorder specially designed for GFM500 backup battery is designed; The 10h rate discharge current is 1 / 10 of the nominal capacity (C / A), that is, 50A; and the nominal working voltage of the standby battery pack used on the site of the iron tower, communication base station, and small and medium-sized data centers is usually 48V, that is, 24 cells are connected in series. In use, the standard discharge time to 43.2V (1.8V × 24) is not less than 8 hours.

[0062] There are two differences in the design scheme of this embodiment compared with Embodiment 2:

[0063] 1) Due to the large discharge current, the high-power ceramic resistor used in the arrester 1 should meet the requirements of high temperature resistance, and it is designed to discharge the monomer. The rated impedance of the arrester is designed to be R=2V / 50A=0.04 (ohm);

[0064] 2) The time for collecting and rec...

Abstract

The invention provides a discharge recorder for storage battery repair and a data recording method thereof. The discharge recorder comprises a discharger, an electric control switch, a control module, a data display meter and a shell; the discharger is rated impedance and is electrically connected with one end of the electric control switch; the other end of the electric control switch is electrically connected or electrically connected with a power supply end through a manual switch; a control program is stored in the control module, the control end and the signal input end are connected with the electric control switch, and the signal output end is connected with the data display meter; preferably, a data end and a heat dissipation device are arranged; the open-circuit voltage value of the no-load sampling time set when the storage battery is discharged to the standard gauge termination voltage can be recorded and displayed on the data display table, the sampling time is set within the time domain of 10-60 seconds when the storage battery is discharged for 2-5 hours, and the sampling time is set within the time domain of 60-300 seconds when the storage battery is discharged for 10-20 hours.

Description

technical field [0001] The invention relates to special equipment for battery repair, in particular to a discharge recorder for battery repair and a data recording method thereof. Background technique [0002] Lead-acid battery is the most used secondary battery on the market, usually referred to as battery. Stations and other high-power / large-capacity fields occupy the mainstream position, especially the utilization rate of solid waste can reach 99%, which can be almost completely recycled, which is in line with the social development trend of green environmental protection. [0003] Batteries have the disadvantage of short service life. Taking batteries for electric bicycles as an example, the warranty period of well-known manufacturers in the industry is 15 to 18 months, and the amount of batteries discarded each year exceeds 1 billion, which is an alarming amount. As a result, the battery repair service has arisen in the market terminal, so that the battery can continue...
