Method Of Battery Charging

By -

 The method of battery charging depends on the type of battery being charged. Here are the general methods for charging common types of batteries:

Method Of Battery Charging:

1. Constant Voltage Charging: This method is commonly used for lead-acid batteries, including automotive batteries. The charger supplies a constant voltage, typically around 13.8 to 14.4 volts, while the current gradually decreases as the battery charges. Once the battery reaches its full charge, the charger switches to a lower maintenance voltage to keep the battery topped up.


2. Constant Current Charging: This method is often used for lithium-ion (Li-ion) batteries and some rechargeable nickel-cadmium (Ni-Cd) batteries. The charger supplies a constant current, usually based on the battery's capacity or a specified charging rate. As the battery charges, the voltage gradually increases until it reaches a predetermined threshold. At that point, the charger switches to a voltage-limited mode to complete the charging process.


3. Trickle Charging: Trickle charging is a low-current charging method used for maintaining the charge of fully charged batteries over an extended period. It is often employed for small lead-acid batteries, such as those in motorcycles or emergency backup systems. Trickle chargers provide a very low current to compensate for self-discharge and keep the battery fully charged.


4. Fast Charging: Fast charging techniques are used to rapidly charge batteries in a short period. This method is commonly employed for certain Li-ion batteries and other advanced battery technologies. Fast charging typically involves carefully controlling the current and voltage supplied to the battery to ensure safe and efficient charging. Fast charging may require specialized charging equipment and should be performed according to the manufacturer's guidelines to avoid potential battery damage or safety risks.


It's important to note that specific charging methods, rates, and requirements can vary depending on the battery chemistry, manufacturer's recommendations, and safety considerations. When charging a battery, it is advisable to use a charger specifically designed for the battery type and follow the manufacturer's instructions to ensure proper charging and avoid potential damage or safety hazards.

ERTHING

ERTHING                        Electricity is beneficial for us, but its loss is even more. Electricity can take our lives even if it does not go well. Now we can not get away from electricity because electricity has become part of our life. Light in the darkness, fan in the heat, so much of the electricity around us that we They even use it inadvertently. Along with this, the risk goes up. For this reason, we must definitely adopt a path of goodwill which can secure us and our own electricity so we must definitely do our work in our home to avoid all these. But first, do you know what the meaning is?  What is Erthing?            We have so many electric appliances in our house around us that sometimes we have been using it. Therefore the electrical equipment is in contact with our body, and therefore whenever there is a fault in the instrument then the body of the instrument comes in contact with us, so that the current passes through our body and we feel shock O

Distribution Transformer and Power Transformer

Distribution Transformer:                                     The transformer is used in the distribution of electrical energy. It is called Distribution Transformer. Its rating is 200 KVA and it is a step down type. In this transformer whether the load is loaded or not, it is functioning 24 hours a day. This means that iron lasts continuously throughout the day while copper is based on the load load. So much so that the load more loads of copper loses and loads less as copper Iron deficiency in such transformer should be lower than Copper Loss. In other words, the transformer's efficiency should be greater on the 50% load. Such transformer's voltage regulation should be good. Power Transformer:                                      The transformer that is used for the transmission of electrical energy is called a power transformer. The rating of this transformer is 200KVA. Power transformer can be used to step up or step down the voltage on both ends of the power l

D.C 3 POINT STARTER

                                 It can also be called a three point starter. Its structure is shown in Figure. To start the motor, the handle is moved from off position to the first contact position. The total obstacle is in the armature circuit, the field connection is connected directly to the supply through a volt coil. Comes in as soon as the speed of the motor increases in the same way as the archete back emf emits and decreases in the value of current Now the handle is moved to the second step. Again this type of function will be done eventually at the last step of the handle. This time the armature will connect directly to the supply and this time the handle does not come with a no-volt coil. The magnet will hold the handle in the walt coil, and the motor will not need to hold the handle to continue and the motor will rotate in full speed.                   Mechanism of 3 points Starter is done so that if the magnetism of the nvc coil is exhausted for any reason, and the
