You might charge your phone, tablet, laptop, and even your automated vehicles, ATVs, and RVs on a daily basis without thinking much about the charging devices that help you use these devices in the first place. It's time to unveil how the battery operates to charge your devices.
The most common kind of technology used in chargers is floating battery technology. This is an advanced technology that maintained the charge of the battery by offering a disrupted current and voltage at a considerably low level accompanying the battery to stay in fully charged or near to full charged condition. These chargers maintain the charging of batteries by consistently providing current in small amounts whenever necessary. It implies that your battery remains fully charged despite the self-degradation losses because the battery will supply a continuous flow of charge to make up for that lost charge.
Floating chargers are mostly used for emergency power supply and backup applications and devices. This type of charger is most suitable for batteries that are not discharged frequently. But due to their capability of offering a low than nominal current, these chargers are not suitable for high backup requirement applications. Rather, you can comfortably use these for low backup requirements.
A voltage is pre-specified for such float chargers. When the battery level drops from a certain specified voltage level, the charger begins to get charged again to maintain the battery charge.
Floating batteries are mostly used with lead acid batteries If you ever use them with value-regulated batteries then you need to be a bit cautious because you can come across the issue of thermal runaway. To prevent this issue you can use the feature of temperature compensation in your battery. This feature enables the changes to maintain the floating current as per the temperature fluctuations.
Float battery chargers are preferred by the masses due to the benefits it offers. They are exceptionally safe to use and save your battery from overcharging and damage. It is also available at affordable rates and is quite easy to connect.
Float chargers are widely used in UPS, car batteries, emergency lights, and other such devices.
Floating Battery Chargers for Cars
Floating battery chargers are perfectly capable of charging the car battery. Considering trickle battery chargers and other chargers, the performance of floating chargers is far superior. Do you know why? Because they offer a continuous current charge to the battery. The current is so low and minimal from the nominal current of the battery that it excludes all chances of overcharging thus saving your battery from getting over-charged and damaged.
Float chargers are a perfect fit if you don’t use your cars on daily basis. If you are an occasional driver then you must know that the car battery has the tendency to self-depletion which will ultimately lead to battery damage. Float charging helps you to maintain the voltage lost due to self-depletion and keep your battery fully charged or in a more practical sense near to full charge. This is why it is the ultimate choice for you if you tend to store your car for a long in your garage. It also enhances the lifetime and performance of your car battery. It is, in fact, safe to even connect the floating charging permanently to the battery without causing any sort of damage to your car battery.
These chargers have an in-built tendency to shut off when they fully charge your car battery. They start to recharge again when the car battery voltage drops down from a certain pre-specified limit. Once that limit is reached they tend to send the current to recharge the battery. This mechanism keeps on repeating which is why it is called a ‘floating’ charger because the current keeps floating in the charger to maintain the battery charge.
Floating Battery Charging
Float battery charging is done when the current floats inside the charger to maintain the voltage of the battery. The charge or current floats when it reaches the deadline or the preset voltage range. When the voltage drops from that range, the chargers start to float the current.
During charging, the battery, charger, and load are usually connected in a parallel fashion. The charger gets power from the normal power supply grid and offers current to the connected load while operating. It means that it channels the charge to the load from the power supply. Being connected in a parallel manner implies that you will get an uninterrupted and continuous power supply.
In case the normal power supply line fails to offer the required power, the floating battery jumps in to offer a backup power supply until you restore the normal power line.
Battery Floating Charging Voltage
The voltage at which the battery is maintained is referred to as float voltage. The battery tends to be fully charged at this voltage level which implies that it does not leave room for the lost power due to self-discharge. The voltage is usually kept constant throughout the charging process. The voltage varies with the build and chemistry of the battery and the temperature fluctuation. If you maintain the voltage as per the type of battery along with the proper temperature, then you can keep the charger connected to the battery for as long as you desire without causing even the slightest damage to the battery.
Normally for a 12V battery, the voltage in the battery is maintained at around 2.25 volts per cell or approximately 13.5 volts in total. For this voltage, the battery floats the charge without overcharging the battery or without boiling the electrolyte implying that no damage is done.
But due to the low current and low voltage, the charging process is also slow. It will take a considerable time to charge your battery with float chargers as compared to charging on normal electric voltage. This is why these chargers are a perfect fit for you if you have time to recharge your battery or can leave the charge on overnight.
