In this post I have explained a four simple yet a safe way of charging a Li-ion battery using ordinary ICs like LM317 and NE555 which can be easily constructed at home by any new hobbyist.
This lithium battery charger circuit automatically cut off the charging process when the full charge limit of battery is reached (i.e-4.2V) . This circuit also protect our battery from over discharging by automatically cutting the output power when the battery voltage falls below 2.4 volt.
In this tutorial, we are demonstrating a Li-ion Battery Charger Circuit. Li-Ion batteries usually require constant current, constant voltage (CCCV) sort of charging calculation. A Li-Ion battery ought to be charged at a set current level (regulating from 1 to 1.5 amperes) until it arrives at its peak voltage.
The circuit that charges the battery by supplying the charge carrier (i.e-electrons) to it is battery charger circuit. Most of the rechargeable battery has common problem of over charging and over discharging. we need a smart charging solution that protects our battery from over charging and damage cause by over charging.
This lithium-ion battery charger circuit utilizes an LP2931 controller IC. The diode is working as a blocker / current blocker to prevent the current flow back into the IC when there is no voltage on the IC input. The yield voltage can be adjusted with a 50k potentiometer between 4.08V to 4.26V. The circuit gives 100mA of charging current.

Also, if you keep the full charge level of the charger at 1V lower than the actual full charge level of the battery, then an auto-cut off will not be needed. So basically, the 4rth circuit is unnecessarily complex, you can actually charge your batteries effectively and safely using any simple CC CV voltage regulator circuit.
Solar PCB boards integrate solar cells and circuit boards to convert solar energy into electricity through the photovoltaic effect. The manufacturing process of solar PCB boards is similar to that of traditional PC. Environmental Friendliness and Energy Efficiency: Solar PCB boards have minimal impact on the environment and do not produce harmful substances such as carbon dioxide. Solar energy is an infinite renewable energ. Efficiency Affected by Environmental Factors: The efficiency of solar PCB boards is influenced by environmental factors such as high temperatures and cloudy weather, which can reduce the conversion efficiency of solar cells.

The PWM implementation, which becomes the crucial aspect for the circuit is achieved by feeding a sample feedback signal to the internal error amplifier of the IC through its non-inverting input pin#1. This PWM input can be seen hooked up with the output from the buck converter via the potential divider R8/R9, and this. The IC has two error amplifiers set internally for controlling the PWM in response to external feedback signals. One of the error amp is. The power stage shown in the design is a standard power buck converter stage, using a hybrid Darlington pair transistors NTE153/NTE331. This hybridDarlington stage responds to the PWM controlled frequency from pin8/11 of the IC and operate the buck converter. For solar panels with higher voltages, such as 60 V solar panels, the design can upgraded by adding zener diode regulator at pin12 of the TL494, as shown below:.

Simple solar charger circuits are small devices which allow you to charge a battery quickly and cheaply, through solar panels. A simple solar charger circuit must have 3 basic features built-in: It should be low cost. Layman friendly, and easy to build. Must be efficient enough to satisfy the fundamental battery charging needs.
This must be precisely set such that the emitter produces not more than 1.8V with a DC input of above 3V. The DC input source is a solar panel which may be capable of producing an excess of 3V during optimal sunlight, and allow the charger to charge the battery with a maximum of 1.8V output.
Solar Battery Charger will take the dc input from the solar panel and will regulate the voltage in order to charge the battery from it. The solar battery charger circuit which we are making is made up of electronic components which are easily available on market as well as online.

This article explores how an Wall Adapter to Battery Changeover Circuit works, how it is designed and how it is built using the LTC4412 integrated circuit.
simulate this circuit – Schematic created using CircuitLab If you always want to use the line-powered switching power supply in preference to the solar-charged battery, then arrange that power supply to put out a little higher voltage than the battery. It doesn't need to be much, even just a few 100 mV would do it.
In this switching circuit, the source of power supply to a load circuit is changed between the battery and DC power. The main components that play important roles in the functioning of this circuit are the relay, switching transistors, and zener diode. In this circuit,three relays are used.
The final power output of this automatic switching circuits will be used to power 12v devices (30 Ampere maximum). It is important that the circuit provides uninterruptible power during switching and that it works in 11-14v range. P.S.: please provide a detailed list of the scheme and electrical components to be used. @Arsenal Why not?
Portable equipment that can operate from a battery pack or an external power source (such as a wall-adapter or external supply) needs to be able to smoothly switch between the two power sources. This application note describes a circuit (Figure 1) that switches power sources with good efficiency and without switching noise. Figure 1.
Take a look at the PowerPath Controller LTC4412 or the Prioritized PowerPath Controller LTC4417 from Linear Technology. They have some more of these PowerPath devices. Or you can take a relay. The wall adapter controls the relay to open/close the line to the battery. AC wall adapter plugged in, relay on and battery line disconnected, vice versa.
When the adapter is plugged in, V1 will be 11 volts (ish). When the adapter is removed, your circuit will have 8 volts at V1 from the battery. There is no risk of the battery being charged by the adapter as the battery diode will block all current in the reverse direction. The diode part numbers are not critical.
