Embodiment Construction

[0023] According to the capacity and discharge current requirements of the storage battery, the present invention consists of one or more constant current discharge modules connected in parallel, and each discharge module is connected by a communication line. The principle block diagram is as follows figure 1 shown. The battery is connected to the input switch of each discharge module, and each discharge module controls the input quantity of its own resistance bar switching switch and adjusts the current supply to the DC converter to adjust the discharge current of the battery according to the data and instructions sent by the main discharge module , for discharge operation.

[0024] figure 2 A block diagram of a single discharge module is given. Each discharge module is mainly composed of an input switch, a discharge voltage and discharge current detection circuit, a microprocessor, a plurality of switching switches, a DC converter, a plurality of PTC thermistor strips and...

Abstract

The invention discloses a shunt-wound rechargeable battery heavy constant current discharging device. The device is characterized by comprising one or more constant current discharging modules which are connected with one another in parallel by communication lines, wherein each discharging module is connected with a rechargeable battery; and the charging modules realize the coarse adjustment and fine adjustment of a discharging current by controlling the number of switches and regulating a given value of current fed to a DC converter. The device ensures high discharging current control and adjustment accuracy, has a simple structure, and can realize parallel connection among the discharging modules with different capacities and different current distribution modes such as an automatic current distribution mode, a manual current distribution mode and the like in the parallel connection.

Description

technical field [0001] The invention relates to a large-current constant-current discharge device for a parallel-connected storage battery, which belongs to the field of industrial detection. Background technique [0002] At present, batteries based on lead-acid batteries are widely used in important departments such as electric power, railways, banks, and telecommunications to provide uninterrupted DC power supply for protection, control, communication, computer and other equipment or provide AC uninterrupted power supply through UPS. The service cycle of the above-mentioned uninterruptible power supply system mainly depends on the service life of the battery, and regular charging and discharging maintenance of the battery is of great significance to effectively improve the service life of the battery. [0003] In addition, with the increasing shortage of traditional petroleum and fossil energy and the need to develop a low-carbon economy, various forms of electric ve...
