A trickle charger is typically low-current (usually between 5–1,500 mA). They are generally used to charge small capacity batteries (2–30 Ah). They are also used to maintain larger capacity batteries (> 30 Ah) in cars and boats. In larger applications, the current of the battery charger is only sufficient to provide trickle current.
One comparison using the DC distribution system instead of the traditional AC system for a Platform Supply Vessel (PSV), reduced the weight of the electrical system components from 115,520 kilograms (254,680 lb) to 85,360 kilograms (188,190 lb). [citation needed] Another saves 15-30% fuel. [2]
A charge controller, charge regulator or battery regulator limits the rate at which electric current is added to or drawn from electric batteries to protect against electrical overload, overcharging, and may protect against overvoltage. [1] [2] This prevents conditions that reduce battery performance or lifespan and may pose a safety risk. It ...
Cruising yachts usually have an auxiliary engine, and there are two main uses for it: One is to power ahead or motor-sail at sea when the wind is light or from the wrong direction. The other is to provide the last 10 minutes or so of propulsion when the boat is in port and needs to be manoeuvred into a tight berth in a crowded and confined ...
The other drove a three-phase electric generator providing power for the onboard air compressor and battery charger. There were more than a tonne of large 12-volt batteries on board, supplying the DC electric motor which could be operated alone or in tandem with the main engine on a chain-coupled drive for turning the 80 kilogram, five-bladed ...
Trickle charging is the process of charging a fully charged battery at a rate equal to its self-discharge rate, enabling the battery to remain at its fully charged level. This state occurs almost exclusively when the battery is not loaded, as trickle charging will not keep a battery charged if current is being drawn by a load.
