When thinking about batteries, you probably also think about battery chargers. Good battery chargers are essential, because the performance and life-span of a battery depends greatly on the quality of the charger.

Emrol is where you can always find the right battery charger. We offer battery chargers for all sorts of battery driven applications including cleaning machines, forklift trucks, access equipment, electric wheelchairs, electric golf carts and caddies, cars and commercial vehicles, etc.

Which charger should you choose?

In order to get the maximum performance from your battery, the battery charger should be matched with the battery. Our extensive range of battery chargers consists of two main groups: traditional chargers and high frequency chargers.

The most important difference between these two groups lies with the transformer. The transformer is needed to convert the current from the high network voltage to the low battery voltage.

Network supply voltage comes via the wall sockets at a frequency of between 50 and 60 hertz. The transformer needs a large iron core at this frequency around which copper wire is wound. Battery chargers that have transformers with an iron core and copper windings are called traditional battery chargers.

High frequency chargers have extra components that initially convert the network supply voltage to an even higher frequency (e.g. 100,000 hertz). In the next phase ‘traditional’ transforming takes place, although at this frequency the transformer is much smaller with a smaller iron core and fewer windings. This makes the charger more compact and lighter than the traditional chargers.

Let’s now go back to the original question: …which charger should you choose? Dimensions and weight can play an important role in making a decision. Although in addition to the requirement for technical compatibility, there are other criteria that play a role in making the final selection:

  • How much do you want to spend?
  • How much energy does the charger consume?
  • Is it an ‘intelligent’ charger?
  • Is it going to operate in a dusty and/or humid atmosphere?

The following diagram provides a concise overview of how both traditional and high frequency chargers score with respect to the above requirements. This overview acts simply as a guide in your search for the correct charger. The product pages for traditional chargers and high frequency chargers go more deeply into the features and options available with these groups of chargers.
