Problems solved by technology

During the high-speed operation of the RTG heavy box, the power battery continuously stores and discharges (charges / discharges) rapidly, frequently, high-power, and high-current energy, which will cause potential safety hazards in the operation of the power battery.
[0004] Therefore, in order to ensure the safe operation of the hybrid RTG and prevent the power battery from overheating, overcurrent, and damage to battery life due to long-term violent charging / discharging, a safety limiting device for energy storage and discharge is needed.
There is no report on the hybrid RTG power battery energy storage and discharge grading limiting device of the present invention

Embodiment Construction

[0034] The specific embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] Please refer to figure 1 , figure 1 Shown is the schematic diagram of safety limit for energy storage and discharge of hybrid RTG power battery. The RTG hybrid power supply system includes a diesel-electric unit 001 as an auxiliary power source and a power battery 003 as a main power source. The diesel-electric unit 001 is connected to the DC busbar 006 through the AC / DC converter 002 and the auxiliary power circuit breaker 004, and the power battery 003 is connected to the DC busbar 006 through the main power circuit breaker 005. The hoisting mechanism drive motor 008 is connected to the DC busbar 006 through the DC / AC converter 007 . The classification limiting device of this embodiment includes a current sensor 102 for real-time detection of the charging / discharging operating current of the power battery 003, a temper...

Abstract

The invention discloses a graded limiting device for energy storage and discharge of a hybrid RTG (radioisotope thermoelectric generator) power battery. The device comprises a current sensor detecting a charging / discharging working current of the power battery in real time, a temperature sensor detecting the working temperature of the power battery in real time, a graded limiting arithmetic unit, a parameter regulator, a graded limiting switch and a graded limiting potentiometer. The invention also discloses a graded liming method for energy storage and discharge of the hybrid RTG power battery. The graded limiting device can perform real-time graded safety limiting on energy storage and discharge of the power battery, ensures safe operation of a hybrid RTG, prevents the phenomenon that the battery suffers from superheat and over-current, and the battery life is shortened because the power battery is subjected to long-term drastic impact charging / discharging is prevented, and the graded limiting method is easy to implement, and good in practicality.

Description

technical field [0001] The invention relates to a hybrid RTG power battery, in particular to a device for limiting energy storage and discharge levels of a hybrid RTG power battery and a limiting method thereof. Background technique [0002] Rubberty container crane (Rubberty regantry, RTG for short) is the main loading and unloading equipment in the world's major container specialized terminal yards. The traditional RTG uses an onboard diesel generator set (referred to as a diesel generator set) as the main power source. Its energy conversion efficiency is low, energy consumption is large, and a large amount of exhaust gas, black smoke and high noise are emitted during operation. These outstanding problems are becoming more and more unsuitable. Meet the increasingly stringent energy conservation and environmental protection requirements. The new RTG hybrid power supply system composed of lithium-ion batteries as the main power source and matched with low-power diesel gener...
