Charger Knowledge

What does that even mean? Charging curve?
Current and voltage during charging can be measured and displayed as a curve over the course of the charging time. Depending on which processes, controls by switch-off (a) or switch-over points (0) are possible with a charger, one speaks of the provided charging characteristics.
Chargers for rescue and safety vehicles
Emergency and rescue vehicles and other safety-related types of vehicles often sit around for months, but when it comes down to it, they need to be ready at a moment's notice to put out fires, rescue injured people or clear roads. Chargers like the Fronius …
Chargers in a workshop
Especially for workshops, there is another charger that supplies the vehicle with power during diagnoses and software updates on the vehicle electronics. During this phase, the vehicle management system requires a particularly large amount of power and …
Chargers for traction batteries
As with supply batteries, traction batteries are used in cyclic applications, i.e. the batteries are used until they are quite empty and are charged during idle times. Here, the charger is part of an effective drive application. The efficiency of the …
Cleanliness pays off
To ensure proper battery function, it makes sense to keep the battery surface clean and dry. Greasy or silicone-containing dirt on the lid can hinder the flow of current. Moisture on the battery can cause a short circuit in the worst case.
Why is the charging voltage of the charger important?
In principle, when charging, the electrons within the battery move from one electrode to the other, in the opposite direction to when they draw current, i.e. discharge. If a discharged battery is provided with too high a voltage from the current or voltage …
Safety instructions for handling acid
Battery acid consists partly of sulphuric acid, which is highly corrosive. It attacks your skin, textiles and even metal. Put on protective clothing! So always wear gloves, safety glasses and possibly an acid-proof apron when handling batteries. Choose …
Charging the vehicle battery now and then
User chargers or consumer chargers are particularly easy to use and easy to maintain. They allow quick charging in between or when the battery is stored for a longer period of time before it is used again, e.g. a starter battery in a classic car that …
Transformer charger versus high-frequency charger
Transformer chargers with a downstream rectifier are relatively inexpensive, but they are large, heavy and less efficient than high-frequency chargers. They allow 1- to 3-step charging methods based on the W-characteristic (W, Wa, WaPuls, W0Wa, WU, WUWa …
How does a charger work?
In principle, the charger reverses the chemical process that provides the current output in the charged battery. To do this, it provides the battery with voltage (in volts) and current (in amps). The charge controller in the charger decides how much current …
