Description

Technical Field

[0001] This utility model relates to the field of mobile charging equipment technology, and in particular to an intelligent charging system for methanol range-extended power. Background Technology

[0002] With the increasing popularity of electric vehicles, the demand for charging stations is growing daily. However, most traditional charging stations are fixed installations that rely on the power grid for power supply. In areas with weak power grid coverage, such as remote rural areas and temporary extensions of highway service areas, it is difficult to quickly deploy charging stations. At the same time, during peak electricity consumption periods, the power grid load is high, and traditional charging stations often cannot achieve high-power charging, affecting the user's charging experience.

[0003] Furthermore, many existing mobile charging stations use diesel generators as their power source, which is not only noisy but also emits a lot of pollutants, failing to meet environmental protection requirements. Methanol, on the other hand, is a clean fuel that primarily produces carbon dioxide and water when burned, making it environmentally friendly and easy to store and transport. Therefore, developing a range-extended charging system powered by methanol is of significant practical importance. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent charging system for methanol range-extended electric vehicles, which solves the problems of traditional charging piles relying on the power grid, poor mobility, high-power charging being limited by the power grid load, and some mobile charging piles having poor environmental performance.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an intelligent charging system for methanol range-extended power, comprising a soundproof enclosure, a methanol fuel range-extending system located within the soundproof enclosure, a charging device, a control system, and an auxiliary system. The charging device includes multiple DC charging interfaces. The control system includes a central controller, sensors, and actuators. The sensors include a methanol level sensor, a current sensor, and a voltage sensor. The auxiliary system includes a cooling system, a heat dissipation system, a lighting system, and a monitoring system.

[0006] By adopting the above technical solution, the methanol fuel range extender system is the core power source of the intelligent charging system, responsible for converting the chemical energy of methanol fuel into electrical energy, and providing stable energy support for the subsequent charging process.

[0007] The charging device includes multiple DC charging interfaces to support the charging needs of different types of electric vehicles. Internally, the charging device incorporates rectification, filtering, and voltage regulation circuits to convert the electrical energy provided by the methanol fuel range extender system into voltage and current that meet electric vehicle charging standards.

[0008] The control system consists of a central controller, a sensor array, and actuators. The sensor array includes methanol level sensors, pressure sensors, current sensors, and voltage sensors, used to monitor the operating parameters of each component in real time. Based on the data collected by the sensors, the central controller controls the start-up, shutdown, and power regulation of the methanol fuel range extender system, as well as the operating status of the charging device. Actuators include various valves, pumps, relays, etc., which execute corresponding actions according to the instructions of the central controller.

[0009] A further feature of this invention is that the methanol fuel range extender system includes a methanol engine, a fuel tank, a power generation unit, an intelligent switch device, and a silencer and exhaust device.

[0010] A further configuration of this utility model is as follows: the silent enclosure includes a lower partition and an upper partition, the fuel tank is located in the lower partition, the upper partition is provided with a first partition and a second partition, the first partition and the second partition divide the upper partition into a first chamber, a second chamber and a third chamber arranged in sequence, the charging device is located in the first chamber, the methanol engine, the power generation device, the intelligent switch device and the cooling system are located in the second chamber, and the silencing exhaust device is located in the third chamber.

[0019] A further feature of this invention is that: the side walls of the second chamber are provided with a plurality of air inlets, and the air inlets are provided with an air inlet silencing device. The air inlet silencing device includes a first housing, a second housing, and a sound-absorbing material filled between the first housing and the second housing. The first housing includes a plurality of spliced ​​baffles, and the second housing includes a plurality of spliced ​​perforated plates. The surface of the perforated plates is provided with a plurality of perforations.
