Abstract

The invention relates to a hybrid power battery pack, an electrical control system thereof, a crane and a system working method. The hybrid power battery pack comprises a plurality of storage batteries which are connected in series respectively. Battery voltage and temperature detecting modules are arranged on the storage batteries. The output ends of the battery voltage and temperature detecting modules are connected with signal collecting ends of a battery management device main machine which is suitable for controlling the charging-discharging parameters of the storage batteries according to the voltage and/or the temperature of the storage batteries, so that the service life of the batteries is prolonged, and the normal working requirements of the electrical control system are met. Generator power is effectively lowered, noise pollution and exhaust emission of a generator are lowered, the operation cost of the generator is saved, and after mounting on an RTG is carried out, RTG flexible transferring working is convenient.

Description

technical field [0001] The invention relates to the field of energy utilization, in particular to a hybrid power battery pack and its electrical control system, a crane and a system working method. Background technique [0002] Conventional RTG (tire crane) adopts diesel engine power generation as the power source of the system, which is easy to use and flexible to operate. It can be operated in various storage yards throughout the terminal, so it is widely used by container terminals. [0003] Due to rising energy prices and rising loading and unloading costs, conventional RTG oil-to-electricity conversion has been or will be rebuilt in many domestic terminals. The RTG is directly powered by the terminal power supply, which greatly reduces diesel consumption and exhaust emissions. However, due to the limitation of the cable length and the position of the trolley line, the electric RTG cannot have the flexibility of being freely interspersed between various sites like the ...
