How Do Onboard Battery Charges Work

Introduction

Marine battery chargers are a great way to keep your battery charged up and ready to go. They work by sending a charging current through your battery, which helps to restore its full capacity. However, before you buy one of these chargers, it's important to understand how they work and what benefits they offer. In this blog post, we'll take a closer look at onboard marine battery chargers and what makes them a such valuable assets for boaters.

To charge a vehicle, all that is needed is a wire and plug for an onboard charger, which is a charger located within the vehicle itself. The onboard charger does transform AC power, which can be found almost anywhere, into the crucial DC power required to charge the battery. The majority of onboard chargers are computer-controlled, which is another feature worth mentioning. It has software that can keep track of the charging rate. As the car battery is charged, the charge rate changes. The battery then enters a floating maintenance mode, which guards against overcharging-related battery damage.

How do onboard marine battery chargers work?

The charger is computer-controlled. The charging rate changes as it charges under the battery. As a result, you won't ever have to be concerned about overcharging. The process for using an onboard battery charger is as follows:

Furthermore, onboard chargers are generally computer-controlled, and the charge rate is modified following the battery's charge status.

The maintenance mode won't harm your batteries after that, so you won't have to worry about them boiling over.

Onboard battery chargers frequently consist of up to four battery chargers that are all housed in one enclosure.

It is not necessary to use a separate current conversion system because the unit has a currency converter.

The computer is then linked to an ac power source, and we are now ready to start. It is possible to convert AC right away into DC.

This charger's automatic algorithm prompts it to begin charging when the battery's voltage noticeably lowers.

To prevent potential battery damage, the device also keeps an eye on the charge rate.

Do I need an onboard battery charger?

For your boat, an onboard battery charger is a must-have if you frequently spend time on the water. Up to four different battery chargers (collectively referred to as "banks") are combined into one onboard battery charger that can be fitted on your boat. Instead of having to charge each battery separately, you can now charge several batteries at once.

Typically, boats have two main kinds of batteries: starting batteries for the engine and deep cycle batteries for other devices like trolling motors, fish finders, and live well pumps. Most contemporary outboard motors with electric starters have an alternator that, once the engine is going, charges your starting battery. That takes care of the starting battery, but the alternator won't recharge your deep-cycle batteries.

You require a unique charger designed specifically for deep-cycle batteries to maintain them. You can avoid the inconvenience of disconnecting your batteries at the end of the day to charge them by having an onboard charger. When you reach land, all you have to do to charge your deep cycle batteries is plug in the onboard charger. Additionally, if your outboard motor doesn't have an alternator, you can still charge your starting battery with the onboard charger.

Is it advisable to leave the onboard charger plugged in?

You must be careful not to overcharge any battery when charging it. A battery's lifespan can be significantly shortened by overcharging it, which can result in irreversible damage. To prevent the battery from being overcharged, basic battery chargers must be closely watched as they charge.

However, the majority of onboard chargers will include some kind of overcharging protection, frequently a float or maintenance mode. The onboard charger will enter float mode and turn itself off automatically once your battery reaches the correct level of charge. The charger will automatically turn back on and start charging the battery if it falls below the ideal level of charge. You can leave your onboard charger plugged in indefinitely without worrying about overcharging your battery if it features a float or maintenance stage.

Where does an onboard battery charger get its power?

In the case of marine vehicles, onboard battery chargers are attached to the power source in your equipment so that it can draw power from the vehicle and transform it into the form the battery needs.

We must choose where to mount the onboard charger before we can install it. The closer the batteries are to each other, the better, but mounting the charger directly above the batteries is not a good idea because gas escaping there could damage it. To avoid a loss in voltage, wire lines should always be maintained as short as possible and should be the proper gauge. More information should be provided regarding the manufacturer's instructions included with the charger.

In a dry, well-ventilated area, mount the charger using self-tapping screws or, even better, stainless steel nuts and bolts.

The charger is often mounted using stainless steel nuts and bolts or self-tapping screws in a dry, well-ventilated area. You then choose the appropriate fuse and install it in the proper location based on the current demand. Finally, we have corrected the charger. Hanging cables should now be properly supported using specific clips, such as plastic clips, to prevent any short-circuiting.

As long as the manufacturer's instructions are followed, one will be able to fix it enough as dictated by established standards. When you're finished, you can simply connect the charger to any power outlet to start charging the battery.

Conclusion

Modern hybrid or all-electric automobiles, as well as maritime vehicles, require onboard battery chargers. It is crucial to the operation and functionality of any motorised vehicle, including boats.

This system differs from the conventional one, which charges slowly and is capable of self-monitoring. They charge more quickly and have highly sophisticated computer software that allows them to monitor their charging process.
