An electro-fluid dual-run drive system

Abstract

The invention discloses an electric fluid type double-running driving system which comprises a battery set. The battery set is connected with a current converter, the current converter is connected with a driving motor, the driving motor is connected with a speed reducer, the speed reducer is connected with a double-acting liquid booster pump, a liquid outlet end of the double-acting liquid booster pump is connected with a load hydraulic motor, the load hydraulic motor is connected with a main driving shaft by a planetary speed reducer, another liquid outlet end of the double-acting liquid booster pump is connected with a driving hydraulic motor, the driving hydraulic motor is connected with a first T-shaped speed reducer, the first T-shaped speed reducer is provided with power generators, the power generators are connected with IGBT (insulated gate bipolar transistor) switching power supplies, the IGBT switching power supplies are connected with first intermittent discharge units, the first intermittent discharge units are connected with a Faraday module capacitor, the Faraday module capacitor is connected with a second intermittent discharge unit, and the second intermittent discharge unit is connected with the battery set. The electric fluid type double-running driving system has the advantages that currents of the storage battery set for providing power can be compensated, accordingly, the balance of the storage battery set can be improved, and the endurance mileage of the storage battery set can be increased.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, in particular to an electro-fluid dual-run driving system. Background technique [0002] From the perspective of industrial civilization, oil and electricity have been the driving force of industry for more than 100 years, and the main difference between "oil" and "electricity" is that the former is a non-renewable scarce resource that will face depletion, while the latter contains a large amount of renewable energy. Renewable energy sources with great development prospects, such as water energy, wind energy, tidal energy, solar energy, etc., can generate electricity, and electric vehicles are products that use batteries as carriers and replace "oil" with "electricity". Recycling energy utilization products are of great significance for saving non-renewable energy. In modern life, because electric vehicles use recycled energy, they meet the national security energy strategy standards, ...

Problems solved by technology

At present, electric vehicle batteries mostly use the method of charging and discharging in series, which will cause great damage to the battery. The reason is that if the performance of the battery in the entire battery pack is degraded, the battery with high performance will be charged when charging, and the battery with the highest voltage will be charged when it is fully charged. Stop charging, and the battery with insufficient voltage will be forced to stop before it is fully charged; when working and discharging, it will discharge the battery with low performance. When the voltage of this battery is too low, the power supply of the whole battery group will be insufficient. The battery pack can't work either. At this time, only the battery pack can be maintained, so the balance of the whole battery pack is also a big problem.
