Remote capacity checking control system and control method for battery pack of dual-power-supply direct-current system

Abstract

The invention discloses a remote capacity checking system for a battery pack of a dual-power-supply direct-current system. The system comprises a front-end acquisition module which is used for monitoring and acquiring the information of the battery pack; a transmission module which is used for receiving and transmitting the battery pack information acquired by the front-end acquisition module; and a rear-end operation platform which is used for receiving the battery pack information transmitted by the transmission module and carrying out remote debugging control. The front-end acquisition module comprises a host, a data convergence device, a single battery acquisition module and a video acquisition module. The transmission module comprises a protocol conversion module and a secure routing module, the host is connected with the protocol conversion module, and the protocol conversion module is connected with the secure routing module. The rear-end operation module comprises a server and an operation platform, the operation platform is connected with the server, and the server is connected with the secure routing module. The invention further provides a remote capacity checking control method for the battery pack of a dual-power-supply direct-current system. The electric quantity of the battery pack is fed back to a power grid, remote capacity checking discharging is achieved, the operation and control are easy, and the reliability is good.

Description

technical field [0001] The invention relates to the technical field of storage battery nuclear capacity, in particular to a remote nuclear capacity control system and control method for battery packs in a dual-power DC system. Background technique [0002] The daily work of battery operation and maintenance management includes the following: 1. Measuring the floating charge voltage of the battery: use a multimeter to test the floating charge voltage of each battery, and the voltage is controlled within the range of 2.24V±90mV; 2. Measure the total voltage of the battery pack: use a multimeter to test Battery pack voltage, the measured total voltage of the battery pack is close to the manufacturer’s set value (within ±1%); 3. Measuring the internal resistance of the battery: use an internal resistance meter to test the internal resistance of each battery, and the internal resistance value is not greater than that provided by the battery manufacturer. Reference value range; 4....

AI Technical Summary

Problems solved by technology

[0004] The existing operation and maintenance management work has the following problems: the positive and negative poles of the battery pack must be disassembled, and improper operation may cause a short circuit accident; the system lacks a set of spare batteries, and the quality of the other set of batteries is not clear, and the risk of system paralysis is high; There is a large voltage difference between the two sets of batteries, and huge sparks are generated when they are connected in parallel; all battery power is consumed by dummy load heat dissipation, and the existence of heat sources is an unsafe factor; waste of battery energy storage, waste of air conditioning refrigeration power; damage to the operating environment of batteries and equipment ;The charging and discharging time is long, requiring maintenance personnel to guard at all times, with high strength and low efficiency
