Description

The charge controller should be able to have over charge protection and low battery cut off and the circuit should be simple to do for beginner without ic or micro controller.

Please sir can you make me a 12v, 28.8AH lithium ion battery,automatic charge controller using solar panel as a supply, which is 17v at 4.5A at max sun light. The circuit stage comprising T1, T2, and P1 are configured into a simple low battery sensor, indicator circuit Points were also awarded for ease of connection, features such as USB outlets, and overall value. Solar: Plan ahead The last line in the request suggests an LED version to be designed for replacing and upgrading the existing CFL fluorescent lamps. The same may be implemented by simply eliminating the battery and the inverter and integrating theLEDs with the solar regulator output, as shown below:Cold weather slows down the chemical reactions inside the cells and even the summer heat can speed up the battery ageing process - leading to reduced performance or failure. If you are only doing short journeys or not using the car often, the battery might not have a chance to be recharged by the engine, and eventually you’ll need a top-up or a jump start – usually at the most inconvenient time. The 'THINFILM' technology allows a wider spectrum of natural light to be absorbed, meaning the unit can still generate electricity under cloudy winter conditions. This technology also enables the solar panel to handle the intense heat of the summer sun with little power loss due to the rising temperature. The above solar panel regulator may be configured with the following simple inverter circuit which will be quite adequate for powering the requested lamps through the connected solar panel or the battery. Parts list for the above inverter circuit: R1, R2 = 100 ohm, 10 watt

If the typical two- or four-battery charger doesn't cut it for your needs, you can find devices with eight or even 16 slots. However, this EBL product can charge a whopping 40 AA or AAAs at once, making it ideal for households that regularly use bulk quantities of batteries. As the input current rises, the battery starts drawing more current, this build up a voltage across R3 which is translated into a corresponding base drive for the transistor. Let's assume in the diagram, the panel open circuit voltage to be 20V and the battery to be rated at 12V. I am currently working on online content for the program, which will focus on young learners(Grade 4-6) learning the basics of electricity, in particular, renewable energy, i.e. solar in this instance. Through a self-directed learning program, children learn and explore about electricity and energy, as they are introduced to a real-world project, i.e. providing lighting to children sheltered in the refugee camps around the world. On completion of a five-week program, children are grouped in teams to construct solar lights, which are then sent to the disadvantaged children around the world. The circuit should use relay or bjt transistors as a switch and zener for voltage reference thanks sir hope to hear from you soon!This condition prevents and safeguards the battery from getting overly discharged and damaged. In such situations the battery might need an external charging from mains using a 24V, power supply applied across the solar panel supply lines, across the cathode of D1 and ground. Car batteries are under constant demand, even when the car is switched off. The battery has to start your car, demist the windows, keep the alarm system running and generally power many functions drivers take for granted. It’s little wonder that they can lose charge over time and need a top-up. In an ideal world, you’d probably just use a mains battery charger but not everyone can park in easy reach of a plug. That’s where solar car battery charges come in. Conversely if you could keep the panel voltage unaltered yet extract the best possible charging option from it, would make the system work with MPPT principle. Firstly think about where the panel will go. If you have a van or motorhome, some waterproof panels can be fitted on the roof permanently.

These lights are good except that they have a mini solar panel and a bright LED with a life of ten years if not more ,but with a rechargeable battery without a provision for its replacement when dead after two or three years of use.It is a waste of resource and unethical. This solar panel should be capable to keeps these lights all the night and will turn OFF at dawn.Please also help me and give details about this circuit/project. A relay is introduced in the circuit and is wired with the LED module such that it's switched ON only during the night or when it's dark below threshold for the solar panel to generate the required any power. We'll also need a solar charge controller for charging the battery, and since the battery would be charged for the period of around 8 hours, the charging rate will need to be around 8% of the rated AH, that amounts to 80 x 8% = 6.4 amps, therefore the charge controller will need to be specified to handle at least 7 amp comfortably for the required safe charging of the battery. The 1.5V battery charger in the design is built using another low power BJT configured in its emitter follower configuration, which allows it to produce an emitter voltage output that's exactly equal to the potential at its base, set by the 1K preset. This must be precisely set such that the emitter produces not more than 1.8V with a DC input of above 3V.Put simply, a solar panel would work most efficiently if its maximum instantaneous voltage is not dragged down close to the connected battery voltage, which is being charged. The load for the left LM338 is the battery which is charged from this LM338 stage and a solar panel input source. The resistor Rx is calculated such that the battery receives the stipulated amount of current and is not over driven or over charged. The circuit diagram shows a simple set up using the IC LM 338 which has been configured in its standard regulated power supply mode. Using a Current Control Feature The above explanation reveals how the IC LM338 can be simply used for making an useful solar LED light circuit with an automatic charger. 4) Automatic Solar Light Circuit using a Relay
