A load-isolated gasoline-electric hybrid power system

Abstract

The invention belongs to the technical field of power equipment, and relates to a load isolation type oil-electric hybrid power system. A central controller is in electrical information connection with each component, and a fuel engine is connected with a generator. A first adjusting switch is connected with a second adjusting switch in series and then is connected with a third adjusting switch and a fourth adjusting switch in parallel to form an adjusting switch set, wherein the third adjusting switch and the fourth adjusting switch are connected in series. The adjusting switch set is respectively in electrical information connection with a first energy storage battery set, a second energy storage battery set and an electric energy output control device. A first battery set management system and a second battery set management system are electrically connected with the first energy storage battery set and the second energy storage battery set respectively. The load isolation type oil-electric hybrid power system is simple in structure, reliable in theory, safe to use, low in cost, long in battery service life, high in energy recycling efficiency and environmentally friendly.

Description

Technical field: [0001] The invention belongs to the technical field of power equipment, and relates to a brand-new fuel engine-driven power system, in particular to a load-isolated oil-electric hybrid power system, which distinguishes the concept of energy from power, and uses the total energy required by the load instead of The maximum power demand match determines the fuel engine rated power and its best steady-state operating conditions. Background technique: [0002] The so-called hybrid power generally refers to the hybrid power of gasoline and electricity, that is, the mixture of fuel (generally referring to gasoline, diesel) and electric energy. A hybrid car has an electric motor as the auxiliary power of the engine to drive the car. It can generate powerful power at the moment of starting, so car owners can enjoy stronger starting and acceleration, and at the same time, achieve a higher level of fuel economy. At present, there are mainly three hybrid forms, one is ...

Problems solved by technology

These gasoline-electric hybrid systems do not distinguish between the concept of energy and power, and their power control mode still adopts the traditional throttle control method, that is, they all satisfy the load directly or indirectly by controlling the throttle opening of the fuel engine. demand, which seriously affects the operating conditions of fuel engines, resulting in unstable operating conditions and deterioration of work, it is impossible to optimize the operating conditions of fuel engines, thereby seriously wasting energy and seriously polluting the environment
