Description

The utility model (PM) relates to the field of electrical engineering, in particular, to devices for charging and discharging batteries with various preset charging algorithms for various types of batteries, including an acid battery desulfation algorithm, has a convenient design with a protective cover for installation and connecting the battery.

A device is known [Patent of the Russian Federation No. 2299638, H02J 7/10, 2003] for accelerated charging of a battery with an asymmetric current, comprising a power unit control circuit including a filter unit, three amplifier units, a battery unit, and a control circuit according to a predetermined algorithm including a control unit connected to a charge algorithm setting unit, a charge mode setting unit and an indication unit, a voltage sensor unit, a power unit connected to supply voltage terminals of ~ 220 V. Analogous features coincide and with the essential features of the PM, are: Control circuit according to a given algorithm, power supply.

This device is capable of continuous discharge of the battery, however, the values of the charging and discharge currents are determined by the capacitance of the capacitors included in the corresponding circuit, which eliminates the possibility of changing the charging or discharge current for various types of batteries. To charge a battery with a large nominal capacity and voltage, the use of capacitors of very large overall dimensions and weight will be required, which makes the use of this device practically unrealizable. Other disadvantages of this device are the lack of stabilization of the charging or discharge current during mains voltage fluctuations and the absence of galvanic isolation of the battery from the mains.

Closest to the proposed technical solution is the device "Automatic charge-discharge station" [Patent of the Russian Federation No. 2237268, H02J 7/10, 2006], containing a power part control circuit including a filter unit connected to the supply voltage leads, three amplifier units, a battery unit, and a control circuit according to a predetermined algorithm, including a control unit connected to a charge algorithm setting unit, a charge mode setting unit and an indication unit, a voltage sensor unit, a power supply, soy internal with power supply leads, characterized in that a rectifier unit connected to a filter unit, a line filter unit connected to a network rectifier unit, an adjustable charge current source unit connected to a power supply unit and to the first amplifier unit are introduced into the power circuit control circuit , a high-frequency rectifier unit connected to an adjustable charge current source unit, a filter unit connected to a high-frequency rectifier unit, a key unit connected to a second amplification unit iteli and with the filter unit, the capacitor discharge unit connected to the connection point of the filter unit and the key unit, the load unit connected to the capacitor discharge unit, the adjustable discharge current source unit connected to the key unit, with the third amplifier unit and with the connection point of the key unit , a capacitor discharge unit and a filter unit, an inductor unit connected to a connection point of a key unit and an adjustable discharge current source unit, a battery connection unit connected to an inductor unit, com of the voltage sensor and with the battery unit, and the current sensor unit connected to the battery connection unit, the analog-to-digital conversion (ADC) unit connected to the current sensor unit, the voltage sensor unit and the control unit, are introduced into the control circuit according to the specified algorithm pulse width modulation (PWM), connected to the control unit and with three amplifier blocks, an audible alarm unit connected to the control unit and a control panel unit connected to the charge mode setting unit.

Signs of an analogue that coincide with the essential features of PM are the following blocks: an overvoltage protection unit (an analog filter unit), an auxiliary power unit (an analog power unit), a control unit (single-chip microprocessor with a control unit, a PWM unit, a charge algorithm task unit , an ADC block and a charge mode setting block for an analog), an indication block, a charge algorithm selection block (an analog control panel block).

The reasons hindering the achievement of the technical result are: the lack of an overload protection unit, the absence of a protection unit against incorrect battery connection, the load unit does not have an additional cooling unit, which limits the maximum battery discharge power, and the battery connection unit does not have access protection person to battery during charge.

The task, which PM is aimed at, consisted in creating a cabinet for charging batteries with an integrated charge-discharge desulfation device, which has a simple human-machine interface with predetermined service cycle (charge / discharge) algorithms for various types of batteries, with a design that provides convenient installation and connecting a battery with protection against human access during charging.

The technical result is achieved by the fact that the cabinet for charging batteries contains an overload protection unit, a protection unit against incorrect battery connection, a charge algorithm setting unit, a power supply unit, an indication unit, a discharge cooling unit and a place for installing a battery with a protective cover.

The proposed utility model is illustrated by a drawing (Fig.), Where:

1) power supply;

2) overload protection unit;

3) the unit for setting the charge algorithm;

4) the place of installation of the battery with a protective cover;

5) surge protection unit;

6) control unit;

7) protection block against incorrect connection of the battery;

8) display unit;

9) discharge cooling unit.

The operation of the device begins with the supply of supply voltage to the block of protection against voltage surges (5). In this block, the input voltage supplied to the module is filtered and then fed to the power supply (1).

Power supply side (Error! The source of the link was not found. It generates a supply voltage galvanically isolated from the input circuits for the control unit (6). The supply voltage is supplied to the control unit (6) regardless of whether the battery is connected or not at the moment. charge / discharge This allows you to select its type and set the desired charge algorithm even before giving a command to service the battery.

Battery installation is carried out using a specialized installation site (4), which has rollers for convenient battery installation / removal and a protective cover that prevents free access to the battery during maintenance, as well as reduces battery evaporation during charging.

After installing the battery, the current battery voltage is displayed on the display unit (8). In case of incorrect connection of the battery contacts, the protection unit against incorrect connection of the battery (7) transfers information about this to the control unit, while the start of the battery charge or discharge will be blocked. If the battery is connected correctly, then, using the charge algorithm setting unit (3), the user sets the type of battery and the method of charging it. After selecting the charge algorithm, the control unit (6) starts charging the battery. In the process of charging, the control unit (6) constantly monitors the charging current and voltage, and if they do not meet the specified parameters, this information is communicated to the user. Also, during the operation of the device, the overload protection unit (2) monitors the current consumed by the device, and if it exceeds the permissible range, blocks the battery charge and informs the control unit about the error (6).

The Svetoch-01-01 battery charging cabinet supports four charging algorithms: alkaline battery charge, acid battery charge, desulfation once, desulfation continuously. When charging an alkaline battery, first the control unit (6) determines the current voltage on the battery, and if it is less than 0.8 V per cell, then the battery is precharged, then a transition to a smooth set of charging current is performed. After reaching the desired current level, the device switches to charge mode until the charging voltage decreases by 30 mV or more by one battery cell. When charging an acid battery, the control unit (6) sets the boundary values of the charging current and charging voltage, then the voltage is gradually increased so as to maintain a constant charging current until it reaches the boundary value, after which the voltage remains constant and the current gradually decreases, until it becomes eight times smaller. After that, the unit goes into charge mode for two hours. When choosing a single desulfation, the charge is carried out by reverse currents in the ratio: for three periods of the charging current, one period of the discharge current. In this case, the ratio of charging and discharge currents is 10 to 1, respectively. This charge cycle continues until the boundary value of the charging voltage is reached and the charging current is halved. After that, the reverse current mode is turned off and the charge continues at constant voltage until the charging current is reduced by half, after which the battery is recharged for two hours. When choosing continuous desulfation, the charge mode completely repeats the mode of single desulfation, with the exception that the battery is not recharged for two hours, and instead the battery starts to discharge, followed by a recharge with reverse currents. This cycle sequence is repeated until it is interrupted by the user. In addition to different charge modes, the user can set the mode and only discharge the battery without subsequent charge.

The discharge cooling unit (9) is designed for additional cooling of load elements at high discharge currents and distribution of air flows in the most optimal way for efficient heat removal.

Currently, the company LLC “KRON” made prototypes of the proposed device. Tests have confirmed their performance and compliance with all declared characteristics.
