背景技术Background technique
随着全球经济的不断发展和世界人口的不断增长，人类越来越离不开电能。可现在随着科技的快速发展，许多产品的问世，使人类面对许许多多的供电问题：(1)电能需求的不断增长，而随着传统的化石能源煤、石油、天然气的不断消耗，且它们具有不可再生性，它们已不可能满足我们所有的供电需求；(2)科技的发展，产生了许多电子产品，智能手机、笔记本电脑、平板电脑，还有数码相机等等各种各样的数码电子产品，这些电子产品电池储能不大，但利用频率高且耗电快，也急需解决它们的充供电问题；(3)电动代步车的流行，尤其是家用和物流领域电动车数量日益增加和频繁使用，也要急需解决它们的充供电问题；(4)在无供电电网地区人类的活动日益增加(野外探险、旅游等等)，也要满足他们的一些日常用电需求；(5)随着城市化进程的加快、智能家居的加速发展、智慧城市的迅速发展，以及电动汽车的普及，这就急需一种便捷快速的充供电方式满足供电需求。面对这些问题，我们有必要设计发明一种具有多功能，多用途、智能化的产品来满足这些需求，从而尽快占领这些市场，以获得高的经济效益。With the continuous development of the global economy and the continuous growth of the world population, human beings are increasingly inseparable from electric energy. But now with the rapid development of science and technology and the advent of many products, human beings are faced with many power supply problems: (1) The demand for electric energy continues to grow, and with the continuous consumption of traditional fossil energy coal, oil, and natural gas, And they are non-renewable, it is impossible for them to meet all our power supply needs; (2) The development of science and technology has produced many electronic products, such as smart phones, notebook computers, tablet computers, and digital cameras, etc. Digital electronic products, these electronic products have little battery energy storage, but they are used frequently and consume electricity quickly, and there is an urgent need to solve their charging and supply problems; (3) The popularity of electric scooters, especially the number of electric vehicles in the household and logistics fields (4) Human activities are increasing in areas without power grids (field adventures, travel, etc.), and some of their daily electricity needs must also be met; ( 5) With the acceleration of urbanization, the accelerated development of smart homes, the rapid development of smart cities, and the popularity of electric vehicles, there is an urgent need for a convenient and fast charging and power supply method to meet the power supply demand. Faced with these problems, it is necessary for us to design and invent a multi-functional, multi-purpose, intelligent product to meet these needs, so as to occupy these markets as soon as possible to obtain high economic benefits.
而现在的便携式供电电源：And now the portable power supply:
1、如图1所示，这种便携式供电电源仅仅通过电网给蓄电池充电，然后用蓄电池给一些场合的某些特定设备进行供电，因此它又很多明显的缺点：(1)能量来源单一化(仅仅通过蓄电池的储能来给用电设备进行供电)；(2)供电电源设备会受到外界环境干扰而不能持续供电的缺陷；(3)不能提供多种电压类型的用电设备的供电需求；(4)当在外自驾游、野外探险等长时间户外活动时，不能满足长时间的供电需求，不能完全应对户外的恶劣条件，应用场合受到限制；(5)不能进行能量双向流动，将多余的能量回馈给电网，造成能源的浪费。1. As shown in Figure 1, this kind of portable power supply only charges the battery through the grid, and then uses the battery to supply power to some specific equipment in some occasions, so it has many obvious disadvantages: (1) The energy source is single ( Only through the energy storage of the battery to supply power to the electrical equipment); (2) The power supply equipment will be disturbed by the external environment and cannot continue to supply power; (3) It cannot provide power supply requirements for electrical equipment of various voltage types; (4) When doing long-term outdoor activities such as self-driving tours and field adventures, the long-term power supply demand cannot be met, and the harsh outdoor conditions cannot be fully dealt with, so the application occasions are limited; (5) The two-way flow of energy cannot be performed, and the redundant The energy is fed back to the grid, resulting in a waste of energy.
2、如图2所示，利用太阳能来设计的便携式供电电源，其也有很多缺点：(1)对环境的要求比较大；(2)其功率转化效率极低；(3)虽然有蓄电池可以储能，但其能量也不会满足很长时间的供电；(5)当蓄电池充满电时，太阳能就无法再利用，造成对太阳能源的浪费。2. As shown in Figure 2, the portable power supply designed by using solar energy also has many disadvantages: (1) It has relatively high requirements on the environment; (2) Its power conversion efficiency is extremely low; (3) Although there is a battery that can store (5) When the storage battery is fully charged, the solar energy cannot be reused, resulting in a waste of solar energy.
因此，对于上述问题有必要提出一种智能化多功能便携式供电电源及其控制方法。Therefore, it is necessary to propose an intelligent multifunctional portable power supply and a control method thereof for the above problems.

(2)现在人类对可持续发展环保节能的新型能源的需求愈发强烈，太阳能作为众多可再生能源当中最具潜力的一种，它具有节能、绿色、环保、无地域限制，并且用于吸收太阳能的太阳能板等设备故障率低，维护简单等等这些优点，非常实用。充分利用了太阳能，设计运用太阳能板和柔性薄膜太阳能电池板两种方式来吸收太阳能。主要有两中运行方式：1)当在家里面或开车到户外旅行时，我们可以采用大型太阳能电池板9，将其放在屋顶或车顶等空间大的地方用来吸收太阳能；2)当我们徒步旅行在户外时，我们可以采用柔性薄膜太阳能板7，将它背在身上来收集太阳能。柔性薄膜太阳能板具有体积相对较小，材料本身性能好且柔软性和防水性较好，可以固定在衣服上进行太阳能的收集，非常适合于户外的恶劣环境。(2) Nowadays, human beings have an increasingly strong demand for sustainable development, environmental protection and energy-saving new energy sources. As one of the most potential renewable energy sources, solar energy is energy-saving, green, environmentally friendly, and has no geographical restrictions. Solar panels and other equipment have low failure rate, simple maintenance and other advantages, which are very practical. Fully utilizing solar energy, the design uses solar panels and flexible thin-film solar panels to absorb solar energy. There are mainly two modes of operation: 1) when we are at home or traveling outdoors by car, we can use large solar panels 9 and place them on places with large spaces such as roofs or car roofs to absorb solar energy; 2) when we When hiking outdoors, we can adopt the flexible thin-film solar panel 7 and carry it on the body to collect solar energy. Flexible thin-film solar panels are relatively small in size, and the material itself has good performance, softness and water resistance. It can be fixed on clothes to collect solar energy, and is very suitable for harsh outdoor environments.
利用太阳能是本次设计的一个最大亮点，在家里面时，可以利用本产品来收集太阳能回馈到电网中存储起来；当在长时间旅途或野外活动时，会优先选择利用太阳能来满足一些供电需求并可以把多余的能量存储在蓄电池中，然后在太阳能不足以提供需求时，可以利用蓄电池中存储的电能，这样使产品的利用最大化。下面来说明本产品对太阳能的利用过程：The use of solar energy is one of the biggest highlights of this design. When you are at home, you can use this product to collect solar energy and feed it back to the grid for storage; when you are traveling for a long time or in the wild, you will choose to use solar energy to meet some power supply needs and The excess energy can be stored in the battery, and then when the solar energy is not enough to supply the demand, the electric energy stored in the battery can be used, thus maximizing the utilization of the product. Let's explain the process of using solar energy for this product:
1)如图5所示，说明太阳能回馈电网。采用小型支路并网逆变器结构，这种结构具有效率高，配置灵活，还有最大功率跟踪准确(MPPT)，且不会出现电路失配的状况。如图4所示用到双向变流器3、双向变流器4、薄膜太阳能板7、太阳能板9这些模块，首先太阳光照射到太阳能板上→然后对太阳能板产生的小电压进行升压→小电压经过MPPT—DC/DC变流器3进行升压→升压到高压侧310V左右的直流母线上，此时以DSP芯片为核心的控制驱动电路将双向变流器工作在逆变状态(DC/AC逆变)，并检测电网侧电压、电流、相序→然后将两种太阳能板产生的直流电回馈到家庭电网中存储起来。1) As shown in Figure 5, it illustrates solar energy feeding back to the grid. A small branch grid-connected inverter structure is adopted. This structure has high efficiency, flexible configuration, and accurate maximum power tracking (MPPT), and there will be no circuit mismatch. As shown in Figure 4, modules such as bidirectional converter 3, bidirectional converter 4, thin-film solar panel 7, and solar panel 9 are used. First, sunlight shines on the solar panel → and then boosts the small voltage generated by the solar panel. → The small voltage is boosted by the MPPT-DC/DC converter 3 → boosted to the DC bus of about 310V on the high voltage side. At this time, the control drive circuit with the DSP chip as the core makes the bidirectional converter work in the inverter state (DC/AC inverter), and detect the voltage, current, and phase sequence of the grid side → then feed back the DC power generated by the two solar panels to the home grid for storage.
2)同时在户外时，我们可以将太阳能电池板9产生的电能经过双向DC/DC变流器3模块进行一定的降压然后给电动自行车、电动汽车、笔记本电脑以及蓄电池(锂离子蓄电池、铅酸蓄电池)充电，还可以将产生的低电压同薄膜太阳能板产生的电压经过双向DC/DC变流器4模块进行降压，给各种电子类产品(手机、平板电脑、MP3等等)进行充电。当然，如果遇到太阳光弱时，太阳能板输出电压会比较低，不能直接给电动自行车、电动汽车和蓄电池充电，这时可以将太阳能板的输出电压经过双向DC/DC变流器3、4模块进行两次升压，以达到对电动自行车、电动汽车和蓄电池充电的电压要求，更好的利用太阳能，并提高利用率。2) When outdoors at the same time, we can step down the electric energy generated by the solar panel 9 through the bidirectional DC/DC converter 3 module and then supply it to electric bicycles, electric vehicles, notebook computers and batteries (lithium-ion batteries, lead-acid batteries, etc.) acid storage battery), and the low voltage generated by the thin-film solar panel can also be stepped down through the bidirectional DC/DC converter 4 modules, and can be used for various electronic products (mobile phones, tablet computers, MP3, etc.) Charge. Of course, if the sunlight is weak, the output voltage of the solar panel will be relatively low, and electric bicycles, electric vehicles and batteries cannot be charged directly. At this time, the output voltage of the solar panel can be passed through the bidirectional DC/DC converter 3, 4 The module boosts the voltage twice to meet the voltage requirements for charging electric bicycles, electric vehicles and storage batteries, so as to make better use of solar energy and improve the utilization rate.
当在旅游或其他一些户外活动中遇到长时间的阴雨电气时，此时这个产品可以发挥它很大的作用：使用蓄电池中的电能。结合图4和图6，我们将蓄电池组放在主电路图中的P1、N之间，这样：1)我们可以通过第二级的双向DC/DC变流器4模块将蓄电池的电压降低，来给各种电子类产品进行供电；2)还可以通过第一级的双向DC/DC变流器3模块将蓄电池的电压升高，来满足一些大电压直流设备的供电；3)同时对于蓄电池本身，可以直接来给电动汽车，电动自行车进行供电使用；4)当家里面停电时，蓄电池的电压可以经过第一级的双向DC/DC变流器3模块升高到高压侧310V左右的直流母线上，DSP控制器并让双向变流器2模块工作在逆变状态，将蓄电池的电能回馈到家庭电网，同时实现高压侧的高功率因数，保证310V直流母线上电压稳定，来满足家庭对AC220V电压的短暂需求。When encountering long-term rainy electricity during travel or some other outdoor activities, this product can play its great role at this time: use the electric energy in the battery. Combining Figure 4 and Figure 6, we put the battery pack between P1 and N in the main circuit diagram, so that: 1) We can reduce the voltage of the battery through the second-stage bidirectional DC/DC converter 4 module to Provide power to various electronic products; 2) The voltage of the battery can also be increased through the first-stage bidirectional DC/DC converter 3 module to meet the power supply of some high-voltage DC equipment; 3) At the same time, for the battery itself , can directly provide power to electric vehicles and electric bicycles; 4) When there is a power outage at home, the voltage of the battery can be raised to the DC bus of about 310V on the high-voltage side through the first-stage bidirectional DC/DC converter 3 modules , the DSP controller makes the bidirectional converter 2 module work in the inverter state, feeds the electric energy of the battery back to the home grid, and at the same time realizes the high power factor of the high voltage side, ensures the voltage stability on the 310V DC bus, and meets the needs of the family for the AC220V voltage short-term needs.
