What is it?
High frequency battery chargers are a more efficient way of charging large batteries, such as those used in electric forklifts. Most existing chargers currently used are either of two types: ferroresonant or silicon controlled rectifier (SCR). These are generally less expensive, but also less efficient.
How does it work?
Battery chargers convert standard AC power to DC power to store in a battery. High frequency chargers use more advanced circuitry to convert the power at higher frequencies, which reduces conversion losses and improves charging efficiencies.
What are the most appropriate applications?
The best applications are warehouses or industrial facilities that have significant forklift usage and operate two or three shifts per day. This usually corresponds to at least two battery charges per day for each forklift.
What are the savings?
Switching from standard SCR or ferroresonant chargers to high frequency chargers leads to standard savings of about 7%. This is based on average equipment efficiencies, but it is not uncommon to see savings upwards of 15% depending on the specific existing and new equipment efficiencies.
What are the non-energy benefits?
In most cases, high frequency battery chargers will have a higher power factor than the existing chargers, especially when compared to SCR. If the customer has a large number of chargers and power factor issues, this could help facility power factor and reduce power factor charges.
What is the cost?
As of this writing, costs for these chargers range from $1500-$2500 per unit.
What is high frequency battery charger?
Utilizing IGBT technology, high frequency industrial battery chargers offer high efficiency, precisely-controlled charge curves, and small lightweight size.

Why use high frequency chargers?
That is why working with high-frequency chargers offers numerous benefits: maximum energy saving. longer life span of your battery. reduced heat generation in the battery. lower water consumption. low weight and limited height. Basically, you save a lot of energy and money by opting for a high-frequency charger!
What is the difference between high frequency and low frequency chargers?
The high-frequency chargers are lighter, more compact and a lot more efficient (87%!). These chargers consume a lot less, resulting in lower costs in the long term. So your best choice is undoubtedly a high-frequency charger! These chargers work with average lower and better tuned charge currents than the conventional versions. In addition, they are able to precisely select the correct setting for the battery at that specific moment. Another advantage is that they consume considerably less energy and don't have a high inrush surge current. Low-frequency chargers use more energy when they are switched on, causing costs to increase quickly.
What does it mean when a battery is charged?
Charging properly means that the battery will regain the correct amount of energy in the available time. People who have 8 hours available, will have to add more energy to the battery than someone who can let the battery charge for 12 hours.
When was the first high frequency charger invented?
Why a high-frequency charger is your best choice. The development of the first rechargeable lead-acid battery by Gaston Planté in 1859 was a major step for the battery world. His first model consisted of a spiral roll of two sheets of pure lead separated by a linen cloth, immersed in a glass jar of diluted sulphuric acid.
How does the charge and discharge current affect the life of a battery?
As a rule, the intensity of the charge and discharge currents strongly influence the life span of the battery. The higher the currents, the warmer the battery gets, which can have a detrimental effect on the battery. To prevent this, you need the right charger.
Do battery chargers use less energy?
In addition, they are able to precisely select the correct setting for the battery at that specific moment. Another advantage is that they consume considerably less energy and don' t have a high inrush surge current.
Will you opt for a low- or high-frequency charger?
Everybody surely knows the low-frequency chargers, also known as conventional chargers. These chargers can be recognised by their bulky size and corresponding weight. Despite being well-known, these chargers are also highly outdated. They generate a lot of heat and loose up to 30% of their capacity as a result of this heat development. Furthermore, they are far from cost-effective. On average, they only charge your battery for approx 70%, which isn't really efficient.
