Novel electric multi-functional special purpose vehicle with lithium battery

Abstract

The invention discloses a novel electric multi-functional special purpose vehicle with a lithium battery. A structure of the vehicle includes a drive axle, a driving motor, a pump motor, a gear pump,a DC-DC, an electronic control integrated module, a power battery, a hydraulic oil tank, a storage battery, a front tire, a rear tire, and a vehicle board. By replacement of a hydraulic system drivingthe vehicle to drive by the motors directly driving a vehicle axle, the motors directly take power from the batteries and directly acts on wheels through a mechanical structure, and the energy utilization rate can reach 95%, which is higher than the energy utilization rate of a variable pump-driven hydraulic motor; and at the same time, driving and operating systems are separated from each otherand can be controlled separately according to needs, and beneficial effects, of improving the energy utilization rate, having less vibration, less noise, zero emission, and less repair and maintenanceof the lithium battery, and being capable of remotely maintaining faults of lithium battery software, are achieved.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted power supply, in particular to a novel lithium battery electric multifunctional special vehicle. Background technique [0002] Lithium metal batteries generally use manganese dioxide as the positive electrode material, metal lithium or its alloy metal as the negative electrode material, and use non-aqueous electrolyte solution. In recent years, the environmental problems caused by traditional internal combustion engine vehicles and the shortage of oil resources have made people focus Investing in new energy vehicles, pure electric vehicles have become an important development direction of electric vehicles because they can truly achieve "zero emissions". Lithium-ion batteries have become an ideal power source for new-generation electric vehicles due to their excellent performance. The driving system of the advanced electric special vehicle is charged once, and the use time is about two hou...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the deficiencies of the existing technology, a new type of lithium battery electric multi-functional special vehicle is proposed now. In order to solve the problem of charging the drive system of the electric special vehicle in the prior art once, the use time is about two hours, frequent charging is required, and the energy utilization rate is low. Low, the energy utilization rate of the whole system is more than 60%, especially the low energy utilization rate, which has become a bottleneck problem restricting the subsequent large-scale development, and the energy utilization rate has been improved, and the vibration and noise of the lithium battery are less Small size, zero emission, less maintenance, and the beneficial effects of remote maintenance for lithium battery software failures
