Problems solved by technology

For example, high-power diesel engine power supply: large emissions, serious noise pollution, can only be braked by energy consumption, and low energy utilization rate; elevated trolley line or underframe trolley line power supply: the terminal has a large initial investment, and the equipment has a large impact on the terminal. The dependence on the facilities is heavy, the flexibility of the equipment operation is poor, and the transition is inconvenient, and an external auxiliary diesel generator is required for the transition; cable reel power supply: the maintenance workload and cost of the equipment are high, and the transition must be used Auxiliary diesel unit is realized with poor flexibility, etc.

Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] figure 1 is a schematic diagram of the drive system according to the invention. The drive system generally includes three parts: a power supply module 100, an input module 200 and an output module 300, wherein the power supply module 100 is used to provide electric energy for the output module 300 to drive a power unit (not shown) connected to the output module 300 to work normally. work; when the power of the power module 100 is insufficient, the input module 200 can be started to charge the power module 100 .

[0022] The power module 100 specifically includes a lithium battery system 6 , a BMS battery management...

Abstract

The invention discloses a driving system which comprises a power module, an input module and an output module, wherein the power module is electrically connected with the input module and the output module respectively; the power module comprises a BMS (battery management system), a lithium battery system and a DC/DC converter; the BMS is connected with the lithium battery system; the lithium battery system is connected with the DC/DC converter and outputs circuit through the DC/DC converter; the input module comprises an electric generator, an LCL filter and an ISU rectifier which are sequentially connected in series; the output module comprises a plurality of inverters; the inverters are connected with the DC/DC converter, are connected with each other in parallel, and are connected with the corresponding electricity utilization units. The driving system, provided by the invention, adopts the large-capacity lithium battery as the main power source to realize the purposes of high energy utilization ratio, low cost and small pollution.

Description

technical field [0001] The invention relates to a drive system, in particular to a crane drive system based on an all-lithium battery. Background technique [0002] At present, the power supply of heavy-duty equipment such as rubber-tyred gantry cranes (RTGs) is mainly obtained through the following three ways: power supply by high-power diesel units, power supply by overhead or underframe trolley lines, and power supply by cable reels. With the strengthening of people's awareness of environmental protection and energy saving, the shortcomings of these methods have become increasingly prominent. For example, high-power diesel engine power supply: large emissions, serious noise pollution, can only be braked by energy consumption, and low energy utilization rate; elevated trolley line or underframe trolley line power supply: the terminal has a large initial investment, and the equipment has a large impact on the terminal. The dependence on the facilities is heavy, the flexibi...
