Industrial battery systems that permit for recharging are both affordable and energy saving. However, without the correct charging system, the benefits can be seriously reduced. In this blog post, we will deliver an overview of the various battery charging options available for an assortment of industrial batteries containing how to select the right one for your customers.
Define Battery Category
If you have ever seen the kind of consumer battery charger that plugs directly into the wall for AA batteries, you possibly have a good idea that not every kind of charger works for all types of battery. Before equating the different systems that are accessible, it is vital to determine what type of battery needs to be charged. Bear in mind that some chargers work for multiple types of batteries, while others will work for only one type.
Calculate Charge Time
The size of the battery, in terms of the amps it holds, governs how fast the battery will charge using a specific charger. For example, a battery that is rated at 100 amp hours will require to be charged for around 11 hours on a 10 amp charger in order to attain its full capacity. The smaller the amp rating on a charger, the longer it will take to completely charge a battery. Nevertheless, chargers smaller in amperage, are normally less expensive as well, so it is a subject of the user’s ultimate needs when it comes to choosing the right one.
Compare Types of Battery System Chargers
Now that it is well-defined what type of size battery charger is compulsory, compare the different types of chargers obtainable. The table below outlines the most usual types of battery system chargers.
Kind of Charger Account Attuned Batteries
High Frequency-Ultra efficient chargers (over 90%) that is also tremendously lightweight and budget effective- All lead acid batteries
SCR-SCR stands for “Silicon-Controlled Rectifier” Cost effective with multi-voltage capability-Standard flooded and sealed maintenance-free batteries
Ferroresonant-An industry standard for industrial battery systems-Dependable and less maintenance with low upfront costs-Flooded lead acid batteries
SCR/Ferroresonant Hybrid-These chargers use a blend of SCR and Ferroresonant technology to develop efficacy-Standard flooded and sealed maintenance-free batteries
Selecting a Battery Charger
There are many aspects that conclude the type of charger necessary for a particular application. Selecting the right charger is very significant to insure not only all requests are met but also the charger is not over specified occasioning in a more costly solution than necessary. The primary reasons in establishing charger specifications can be distributed into environmental and electrical categories.
There are many causes that govern the type of charger required for a specific application. Picking the right charger is critical to certify that all desires are met and that the charger is not over specified. One of the chief factors in charger selection is the operating environment.
System Electrical Features
How many batteries are mandatory to be charged? Is it possible to save cost by expending a multi-bank charger as conflicting to a single output unit? For example, consider a 24V system comprised of two 12V batteries in series. The whole battery pack can be charged with a single 24V unit or the two 12 batteries can be separately charger using a CT 500 dual output units.
Do the banks share a mutual negative or are all banks remote? There will be an important cost savings, if the batteries share a common negative. If the batteries are stacked then the isolated output series are vital.
Battery Pack Concerns
If your application entails a stack of batteries to generate a 24/36/48V output, then there are numerous issues to consider both in system design and electing a charger.
When batteries are charged in sequences by a single output charger, there is no way to define if both batteries are being equally charged. Even though the current being applied to both batteries is alike, the capacity, age, specific gravity, etc. of the two batteries may not be close enough, due to aging ensuing in unequal battery voltages.
A single output charger must not be used if the loading off the stack is not the same For example, if there is a 12V load off the first battery and one more from the entire stack, the discharge currents for the two batteries will not be equal and hence equal charging currents will not deliver a balanced charge to both batteries. Likewise, when fabricating a stack all batteries should be the same kind. Again, the multi-output charger compensates for tapped loads by charging and monitoring each battery separately. This could actually save the condition for adding a third battery if a 12V load is required. In any case, the loads should be cut off if any battery voltage is less than 9.5V, since this is a deep discharge and repeatedly draining the battery at this point is not suggested.
Will the charger be used to sustain the charge on a car, lawnmower or other special craft that will not be used habitually and has its own charging system? A maintenance charger can be used for these varieties of applications.
Three State Chargers
If the charger will be the principal charger for the battery then the three state chargers is what you need. This will return 100% capability every time and lessen the voltage when finished to maintain the battery at full capacity indeterminately.
The battery must have the appropriate charging voltage applied. For example, it is satisfactory to apply a 12V charger to two 6V batteries in series since this equals 12V but not to use the charger to charger the batteries independently.
Charging Current Approval
The charging flow is one of the most imperative criteria in choosing a charger. An extreme amount of current will overheat the battery causing in decreased battery life and poor capacity. Some batteries are able to agree to very large charging currents while others are more delicate. You must check your battery specification to assure that you are not using current in excess of the commended amount.
