Figure 1. Composition of Off-grid PV System

2. Major Components of Off-grid PV System

   1). Solar-cell Array. It is the core component of the system, convert solar energy into electric energy. The solar cell modules are installed in series or in parallel in accordance with the requirements of different systems.

   2). Battery. Store the electric energy generated by solar-cell array so as to supply power at the following conditions: light deficient conditions, nights, or when load demand is higher than power supply of the array. The most widely applied batteries in PV systems are lead acid batteries.

   3). PV Controller. It is the core control section of the whole system, controlling the charge/discharge of batteries and the electrical power output of the array and battery pack. Currently, there are mainly two widely applied control modes: PWM and MPPT. The PWM has higher control efficiency but relatively lower utilization rate to solar modules; while MPPT has relatively lower control efficiency but higher utilization rate to solar modules. In most cases, PWM mode is applied in system with smaller power, and MPPT mode is applied in system with lager power, especially when system power is higher than KW level.

   4). Inverter. If AC Load is included in the system, inverter is needed to concert direct current from solar-cell array or battery pack into needed alternate current.

Graphene Battery

Graphene’s huge specific surface area enables it to carry more li-ions and get/loss li-ions more quickly, therefore provides the essential physical foundation for battery to have bigger capacity and quicker charge/discharge speed.

   Battery with graphene as negative electrode has very good charge/discharge rate but very bad cycle life. Researchers are always trying to find an appropriate negative electrode material so as to combine advantages such as fast charging/discharging, long cycle life, high energy density and low cost together.

    Recently, Spain’s El Mundo has reported that Spain’s university has developed a graphene battery which has combined all the above advantages together. It will be first tested in a German’s automotive enterprise.

    On condition that the report is true, this battery will be quite promising. If the recharging time is as short as refueling time, then the charging stations could take the place of gas stations, and electric vehicles could take the place of fuel vehicles.

Conclusion

    Everything real is rational. The lead acid battery and lithium batteryhttp://www.sacredsun.com/productsdetaillithium_125_125_125_125.html are still dominating the market of electric vehicles, not because the manufacturers are stupid, but for other technologies are not mature or lack supporting industrial chain.

    We need to be patient to wait for the next breakthrough in this area.

Flow Battery

 Flow battery belongs to ordinary chemical battery. Its utilization rate of active materials is improved through storing positive electrolyte and negative electrolyte separately.

      Due to the limit of materials and the concentration of the electrolyte, the flow battery didn’t achieve high energy density in past years. It can be applied in energy storage power stations, but not available on vehicles.

     Recently, Dr. Yet-Ming Chiang, scientist of Massachusetts Institute of Technology, has invented a semi-solid lithium flow battery. He has made innovations on material and electrolyte concentration, which enables the battery to reach applicable level on energy density and power density. This battery is still in the laboratory stage.

    NanoFlowcell AG has launched an automobile with flow battery, which seems have reached very high energy density in accordance with its technical index. However, its facticity remains to be verified.

    Compared with previous hydrogen fuel battery and metal fuel battery, flow battery is more feasible. Once the laboratory technology enters into mass production period, it will change the electric vehicle industry dramatically. With flow battery, electric vehicle could run further, become cheaper, and charge faster (charge through power grid or replace electrolyte).

Aluminum-Air Battery

 Aluminum-air battery is also a kind of fuel battery. The “charging mode” of aluminum-air battery is replacing aluminum materials. It is similar to the Zinc-air battery used in hearing aids.

    Aluminum-air battery, a kind of metal fuel battery with high energy density and low power density, can be widely applied in facilities with low power. The only way to apply it on electric vehicle is to use it cooperatively with lithium battery.

    In view of its active chemical property, it is difficult to ensure its security and stability. Therefore, it is still in experimental stage.

    In addition, aluminum-air battery is also confronted with the problem of industrial chain. Both zinc-air battery and aluminum-air battery follow the following circulation:

    1. Metal manufacturer prepare metal through electrolyzing metallic oxide;

    2. Transferring metal to electrical changing station;

    3. Replacing metallic oxide in electric vehicle with metal (metal becomes metallic oxide after discharging);

    4. Metal manufacturer recycle metallic oxide for reutilization.

   In this process, a complete industrial chain is needed, from manufacturing, transportation, replacement, to recycling. Is it possible to build electrical changing stations all around the country?

   As a result, even aluminum-air battery enters mass production period, it can only be applied to vehicles with fixed electrical changing stations, such as city buses and taxis. Just like hydrogen fuel battery, it’s really difficult to achieve overall popularization.

Hydrogen Fuel Battery

  In previous article, we have discussed the technical requirements for electric vehicle batteries and have briefly introduced the basic characteristics of Li-ion batteries and lead acid batteries. Start from this article, we will introduce several advanced batteries for you one by one. In this article, we focus on hydrogen fuel battery.

    Fuel battery is usually nonrechargeable. As a kind of fuel battery, the “charging mode” of hydrogen fuel battery is actually hydrogen filling.

   The advantage of hydrogen fuel battery is 0 pollutant emission. Hydrogen generates electricity, motor drives vehicle. We change gas stations into hydrogen refueling stations and everything seems to be Ok.

   However, the entire process is not as simple as what you see. One problem we need to consider is the manufacture, transportation, and storage of hydrogen. Gaseous hydrogen needs to be stored in high pressure gasholder while liquid hydrogen needs to be maintained at very low temperature which costs excessive consumption of electric energy. It is far more troubling than fuel oil.

    Manufacturing of hydrogen is relatively simple. But if you want to transport hydrogen to hydrogen refueling station, special pipelines are needed. Considering the hydrogen embrittlement, the transportation, storage, and refilling of hydrogen demand facilities with high security.

     For fuel oil and natural gas, we have existing infrastructures to utilize; for lithium battery, we have existing power grid to utilize; while for hydrogen fuel battery, we have nothing. If we plan to manufacture vehicles with hydrogen fuel batteries, we need to build an entire system from hydrogen manufacture, to transportation and storage first. It is really a costly project.

Which Battery is Best for New Energy Vehicle?

Recently, with the promotion of Tesla, more and more new-type batteries for new energy vehicles begin to enter the public consciousness: from hydrogen fuel battery, aluminum battery, to flow battery, grapheme battery, aluminum ion battery, ... It seems that Li-ion battery has been out of date. What on earth is the truth of electric vehicle batteries?

    Now, let’s uncover the truth of electric vehicle batteries.

    Battery is the core problem which limits the development of electric vehicle. For electric vehicles, ideal battery must possess following characteristics:

   1. Enough energy density (has enough capacity at per unit volume and per unit weight), so that the vehicle could run further;

    2. Enough power density (could generate enough power at per unit volume and per unit weight), so that the vehicle could speed up in a short time and achieve climbing;

    3. Fast energy supplements, no matter recharging or replacing;

    4. Low average cost, with competitive advantage on comprehensive analysis of service life and price.

    In current electric vehicle market, there are mainly two kinds of batteries: Li-ion batteries (LFP battery, LMO battery, ternary lithium battery) for high-speed electric vehicles, and lead acid batteries for low speed electric vehicles.

   For Li-ion batteries, the power density and energy density are satisfying, but its recharging time is long and price is relatively high. While for lead acid batteries, although its power density and energy density is relatively low and its recharging rate is slow, its low price result in its extensive application on low-speed and short distance electric vehicles.

   In following passages, we will introduce the advanced batteries mentioned above for you.
