Solar Chargers For Car Batteries

Can The Battery Be Harmed By Usb Charging

The short answer is that charging your phone using a computer or laptop connector is safe.

However, if you need to rush, there is an issue.

Instead of receiving a quick charge, the battery will be charged gradually.

Therefore, if you wish to charge your battery via a USB connection, you need have adequate patience.

But keep in mind that its harmful to often charge your smartphone through a USB connection if you have one.

Why? because your battery cannot always get a constant, reliable current from the USB host.

Therefore, constantly charging a lithium-ion battery through a USB connection from another device risks harming the batterys chemical components.

And as a result, it may immediately harm your smartphone.

Therefore, it is safe to constantly carry a battery charger.

After all that, its advisable to get a new mobile charger that can charge a li-ion battery or fits your mobile phone if you forget to bring your charger.

Your pocket will be spared as well as your mobile device from early harm.

Reverse Charge Blocking Diode

When I first saw this term, I was confused. I may know a lot about solar power, but Im not as familiar with cars. But as Ive looked into it, this feature immediately became a valuable option that I realized is important.

Reverse charge blocking diodes allow the charger to retain all the energy that it collects throughout the day from the sunlight. It then prevents it from leaking out that energy at night when its not in use.

The feature is present in most solar-powered battery chargers, though, so it shouldnt be too difficult to find. Just make note of a mention of the feature or not, as most manufacturers will include this in the description.

Solar Car Battery Charger

The blue flashing LED light will flash as soon as it is the view of a bright light or sunlight, this doesnt specifically mean it is charging. It just means that it is ready to charge when plugged in in its current position in the sun.

Just like above, this solar battery charger is simple to use, we took our car down to our parents and left it there for just over 2 weeks whilst we went on holiday. We left the solar panel on the dashboard facing south and went on our way.

We returned two weeks later, made sure to unplug it all before we started the car and it worked perfectly. The car started first time and our battery seemed to be fully charged. This was in late summer though and there had been decent weather in the time we were away.

This may not be so good in winter and youd need optimal sunlight for it to work perfectly and as expected. In this case, we can also recommend the Sauoki U10 we have also reviewed. With a jump starter you can be sure that if the worst was to happen, you can get your car started and back on the road.

Important Notice

Make sure to remove and disconnect from the connector or battery before starting your car.

Can You Charge An Electric Car With Solar Power

Yes, you can charge an electric car with solar power. Doing so will save you money in the long run versus charging using the electric utility grid.

You have a couple of options when charging your EV with solar power. You can use a dedicated solar charger or connect an ordinary car charger to a solar system.

Understanding how this works helps to know the components of a standard solar power system. Each solar system typically includes:

Solar Panels: consist of photovoltaic cells that convert light to DC electricity.

Inverter: converts DC electricity to the AC electricity that EVs use.

Electric Vehicle Supply Equipment : includes the user interface, software, electrical conductors, and protocols that deliver electricity from the inverter to your vehicles battery.

Battery Storage System: stores the electricity that solar panels produce. This allows for low-cost solar energy to be used at night when the Sun is down.

With a dedicated solar charger, all of this is can be included in one integrated system.

Alternatively, if you already have a home solar panel system, you can connect your home solar and electrical system to an electric car charger.

Make Your Solar Car Charger Look Nice

I picked up a NOCO battery box and plopped my 12V battery right inside.

Then I used a drill and the mounting screws included with my charge controller to mount the controller to the top of the battery box.

Heres how it turned out:

Next, I drilled some holes in the top of the box to feed the battery cables through.

Tip: Drill the holes angled slightly away from each other so the leads wont touch when fed through the lid. You dont want to short the battery!

Then I reconnected everything

And I was finally done:

Im happy with how it turned out. The box makes the whole system more portable and cuts down on cable clutter. It also looks nicer.

• A bit pricier than others

The Deltran Battery Tender is a reliable solar power car battery charger that delivers optimum power to car batteries safely and efficiently. It has a contemporary design that should complement the aesthetics of modern cars. It is easy to use, too.

One of the most striking things about the Battery Tender is the squarish design of its solar panel. Most of the products on the market come in a classic rectangular design. The four corners of the panel already feature a hole for securing it with the accompanying mounting screws. We think adding suction cups would have made installation a lot easier.

You will love the charge controller of the Battery Tender. It features a 3-step microcontroller that allows the system to deliver the appropriate levels of charge to the car battery. The same microcontroller prevents damaging the battery by preventing the risk of overcharging. In addition to these protections, the Battery Tender also has reverse polarity protection. You will not have to worry about your battery losing its charge because the system has drawn it back in.

How Long Do They Take To Charge

Standard solar panels will take anywhere between 4 and 12 hours to receive a full charge.

The average for moderate to high wattage panels is between 6 and 8 hours of direct or mostly bright light charging hours.

During the winter, cloudy weather, or other lower light conditions, the charge time will be closer to the 12 or even 14-hour range.

Do Solar Car Battery Chargers Charge Dead Car Batteries

A solar car battery charger will not be able to charge a completely dead battery.

They are not for this purpose.

Solar-powered car battery chargers are trickle chargers, meaning they charge at a rate thats equal to the self-discharge rate. This enables batteries to remain fully charged at the proper level. However, the battery must not be in use when charging as trickle charging cannot keep a battery charged while in use.

There may be some models designed specifically for fully recharging a car battery, but these are less common and will use a different form of charging known as float charging.

What Features Make A Solar Battery Tender Great

How Safe is it?

This is often overlooked when selecting a battery maintainer. Many devices offer a fast charge for a moments fix, but this can leave you at risk of an overcharge or even shocks. Protection, in the case of car battery maintainers, must cover a multitude of bases. Youll want a device that protects you, your car battery, and even itself. If any of these arent guaranteed safety by the device, then do not purchase that product. There are hundreds of solar maintainers available that do promise protection.

Waterproofing

Batteries never die during an ideal situation. If youre out getting food with a friend who has a car during a sunny day when your battery dies, then youre a lucky one. More often than not, luck is not on our side, and youll need a device that can weather the elements. Dont be afraid to charge your battery when its raining out because your solar car charger isnt waterproof. This is one of the most important features to look for in a solar maintainer.

LED Indicators

Many devices will include LED lights that indicate the charge level. This might not improve the products overall charge, but its nice to know when your maintainer wasnt charged for a situation.
