Marine Batteries

Marine battery charging.

 Proper organization of battery charging on your boat.

Service batteries on the boat or yacht designed for powering onboard equipment. In addition to the service group, the vessel can be equipped with batteries for a bow thruster, an electric boat motor or an anchor winch.

Considering that each group of traction batteries can have a different voltage, capacity and chemical composition, the correct organization

of their charging becomes a difficult task.

The solution consists of several stages.  First, choose a charger that has sufficient power, has profiles for charging the main types of traction batteries and is equipped with two or three outputs.

 Secondly, a decoupling device is selected for charging several battery groups from the propulsion engine generator. It can be either a relay or a battery divider of the appropriate rating.

 Special devices to help you use your batteries more efficiently.

 Autonomous swimming is impossible without monitoring the condition of the batteries. In the simplest case, a voltmeter is used, however, devices that combine a voltmeter, ammeter and ampere-hour meter in one case are much more informative and more accurate. The battery monitor can be designed to work with one group, or to monitor multiple charging sources and panel batteries, recharge the batteries while the engine is not running.

 If traction batteries supply powerful consumers, for example, an inverter, they must be protected from deep discharge. Special devices designed for this disconnect the load as soon as the battery voltage drops below 11.5-12.0 volts. Protection devices are also installed when a single battery is used both to start the engine and to power on-board equipment.

During the movement, the traction batteries are charged from the generator of the propulsion engine of the boat or yacht. However, due to the peculiarities of the generator operation, the charging of the traction batteries takes too long and leads to increased fuel consumption and additional wear of parts if the engine is started on purpose to charge the batteries. Special devices increase the charging efficiency of the generator, and additional charging sources such as solar panels recharge the batteries when the engine is not running.
