This LM350 Car battery charger circuit project schematic is a high performance charger that quickly charges gelled lead-acid batteries and turns off the charger process at full charge . When the current falls to 150 mA , the charger automatically switches to a lower float voltage to prevent the overcharging .

Before building the circuit, you must determinate how much current will be used to charge the battery or battery pack.
A battery is a device for storing chemical energy and converting that chemical energy into electricity.
The electrons are generated by chemical reactions, and there are many different chemical reactions that are used in commercially available batteries. Automobile manufacturers have identified three types of rechargeable battery as suitable for electric car use. Lead-acid batteries were invented in 1859 and are the oldest form of rechargeable battery still in use.
Lithium-ion batteries, which came into commercial use in the early 1990s, have a very high energy density and are less likely than most batteries to lose their charge when not being used -- a property called self discharge. Setting up a webcam sight illuminator over your laptop's webcam will certainly “enlighten” your online conversations.
Instead of using a pull-up resistor to turn the Darlington on, Q3 is configured as a 1mA current source.
There are two modes of operation—voltage regulation or current regulation—the current regulator (when in operation) takes precedence over the voltage regulator.
To use the 24V transformer, a voltage doubler rectifier is required to obtain the raw 53V supply. Note: to keep the series regulator from having to dissipate an unreasonable amount of power, the raw DC voltage should be about 10V higher than the maximum output voltage. There is much destructive power here so it is wise to bring the voltage up gradually via an adjustable DC power supply or Variac powering the transformer primary. When charging a low battery, the regulator will remain in current limit and the voltage will be low until the float charge voltage is reached.

The difference between DC battery chargers and other split charge systems is that whereas a split charge relay is ruled by how the vehicle alternator senses the leisure battery charge the DC battery charger uses it's own micro-processor system to determine the actual level of charge in the leisure battery and tricks the alternator into providing extra charge for long periods in order that the leisure battery reaches full charge. Takes the energy from a vehicle's main battery (engine running) and converts it into multi-stage output for charging an auxiliary battery. When the battery is nod fully charged the charge current is held at 2 A , but as buttery voltage rise , current decreases .

It is advisable to charge the battery with a current that is 10 times smaller then the battery capacity, and to charge it for about 15 hours. If you want to charge faster, then a charge current of 200mA can be used for about 7 hours.
When faster charging is used, it is advisable to discharge the battery completely before charging.
A battery is made up of one or more electrochemical cells, each of which consists of two half-cells or electrodes. For example, the familiar alkaline batteries commonly used in flashlights and television remote controls generate electricity through a chemical reaction involving zinc and manganese oxide.
Those types are lead-acid batteries, nickel metal hydride (NiMH) batteries, and lithium-ion (Li-ion) batteries. They've been used in all types of cars -- including electric cars -- since the 19th century. They have a high energy density -- that is, a great deal of energy can be packed into a relatively small battery -- and don't contain any toxic metals, so they're easy to recycle. Because of their light weight and low maintenance requirements, lithium-ion batteries are widely used in electronic devices such as laptop computers.
The small value resistors R2, R3 , R6  must be 1 watt resistors and R7 must be 5 watts resistors.
One half-cell, called the negative electrode, has an overabundance of the tiny, negatively charged subatomic particles called electrons.


Lead-acid batteries are a kind of wet cell battery and usually contain a mild solution of sulfuric acid in an open container. Some experts believe that lithium-ion batteries are about as close as science has yet come to developing a perfect rechargeable battery, and this type of battery is the best candidate for powering the electric cars of the near future.
The name comes from the combination of lead electrodes and acid used to generate electricity in these batteries. A variation on lithium-ion batteries, called lithium-ion polymer batteries, may also prove valuable to the future of EVs. When the two halves are connected by a wire or an electrical cable, electrons will flow from the negative electrode to the positive electrode. Automobile batteries, on the other hand, need to be rechargeable, so they don't require constant replacement. The major advantage of lead-acid batteries is that, after having been used for so many years, they are well understood and cheap to produce. These batteries may eventually cost less to build than lithium-ion batteries; however, at the present time, lithium-ion polymer batteries are prohibitively expensive.
In a rechargeable battery, electrical energy is used to reverse the negative and positive halves of the electrochemical cells, restarting the electron flow. However, they do produce dangerous gases while being used and if the battery is overcharged there's a risk of explosion.
The energy of these moving electrons can be harnessed to do work -- running a motor, for instance. As electrons pass to the positive side, the flow gradually slows down and the voltage of the electricity produced by the battery drops. Eventually, when there are as many electrons on the positive side as on the negative side, the battery is considered 'dead' and is no longer capable of producing an electric flow.
