Battery Chargers and Power Supplies

A battery charger or recharger is a device used to put energy into a secondary cell or rechargeable battery by forcing an electric current through it. The most important property of a battery charger is that it reaches the exact voltage during the charging cycle. If voltage is too high, the battery boils. The battery becomes unusable due to dried-out cells and crevice corrosion, which occur due to high acid concentration and overheating during charging. If voltage is too low, you end up with an incompletely charged battery that will lose more and more capacity until it gradually becomes unusable.

A power supply is an electronic device that supplies electric energy to an electrical load. The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters.

Dolphin Marine Battery Chargers

Dolphin marine battery chargers were developed by the French manufacturer Power First and launched in 1995. The first generation chargers, many of which are still in operation today, featured cutting edge design and technology and were quickly adopted by professional and leisure boaters alike.

The second generation was launched in 2001. The electronic technology shifted to surface mount design and considerable focus was placed on the aesthetics in order to combine both form and function. It proved to be a successful recipe and was reflected in the Dolphin chargers’ growth around the world in the following years.

The third generation series concept was to develop the product along two separate lines; an elementary range for lower power applications and a professional range for high power demand. Thus the Premium and Pro ranges were born, the former released in 2011 and the latter in 2012. The new range is the culmination of many years of experience gained from an in-depth knowledge and understanding of the marine industry.

• An ISO 9001 certified Research & Development facility in France with a specialized team of electronics engineers
  
• A rigorous quality control department, testing every product before it leaves the factory.
  
• Up to date technology
• A dedicated after sales service
• Sales to date of over 100,000 units, on every continent
• An international network of distributors and service points
• 2 years warranty from date of sale

Enerdrive Battery Chargers

In recent times Enerdrive has embarked on its own manufacturing program. They saw the need to control their own destiny and produce high-end products that the Australian market place was demanding.

This program has led to Enerdrive manufacturing its own range of ePOWER AC battery chargers & DC2DC battery chargers, alongside Lithium battery systems.

This product range is engineered to withstand the demanding applications in marine & mobile electrical systems.

Enerdrive ePOWER Battery Chargers

 

ePOWER Battery Charger Features:

• Multistage Charging: Fully automatic multistage battery charger with the ability to charge 3 separate battery banks.
• Separate Battery Banks: Isolated charging design where battery bank one is separate from battery bank two and three.
• Programmable: Battery bank 1 can be programmed with a different charge algorithm over banks 2 and 3.
• Current Control: User adjustable current output (e.g. Dial the 60amp unit back to run off a 1kVA generator).
• Smart Charging: The ePOWER 20A battery charger will regulate its output based on the loads connected to your battery banks.
• Wide AC Input Range: Operates on both 110V / 60Hz and 240V / 50Hz.
• LED Display: Easy to use “set and select” menu along with scrolling charger status.
• Silent Mode: Disables the cooling fan for total silent operation at night or whenever required. Activation reduces charge output by half and locks out fan for 12 hours.
• Temperature Sensor: Battery temperature sensor included with 3 meter cable.
• 5 Year Warranty from an Australian company renowned for customer support.

Multistage Charging Process

The Enerdrive ePOWER Battery Charger is a fully automatic, “set and forget” charger. It is designed to quickly and accurately recharge your batteries using algorithms that help maximise service life. Multistage smart charging technology enables the charger to be connected to your battery banks permanently.

As dictated by battery manufacturer’s recommendations, batteries require a multistage charge sequence for perfect, fast and accurate charging. The ePOWER multistage smart 20A battery charger delivers four primary charge stages:-

• Stage 1 – Bulk or Boost Charge; The battery is charged at full rated output current of the charger until the battery reaches its final charging voltage, known as its absorption voltage. In this step, around 80% of the battery capacity is recovered as fast as possible.
• Stage 2 – Absorption Charge; With the charger voltage held steady the remaining 20% is replaced allowing the current to drop as the battery approaches its full charge.
• Stage 3 – Float; Finally, in the float stage the charger voltage is lowered and held at a constant and safe predetermined level. This prevents the battery from being overcharged while supporting any additional loads connected to the battery, such as DC lighting and refrigerators. This stage allows for the charger to be used as a DC power supply.
• Stage 4 – Maintenance; This stage is a regular timed “return to bulk” stage. After 7 days of constant operation in “float” the Enerdrive ePOWER Battery Charger will switch the charger from float to bulk to agitate the batteries electrolyte helping to provide an extended service life.

1 PRIORITY - Charge Where You Need it Most

The ePOWER Battery Charger delivers a priority charge to Bank 1, or your main house battery bank which allows the charger to get this bank recharged the quickest, then transition the cycle to the lesser bank 2 & 3 batteries.

The priority function also allows you to have a battery chemistry different to the other two, such as an AGM battery for house and lead calcium for your start banks.

In the event that all 3 banks are in need of a charge, an over-ride function helps recover all 3 banks quickly and evenly before switching back to prioritise on Bank 1.

All About Lithium

The recent advances in high capacity Lithium battery technology have seen the need to develop a battery charger suited to their needs. With most traditional ‘smart’ chargers their suitability to Lithium batteries is limited. Lithium batteries require a constant current / constant voltage charge algorithm and are unique in that almost every amp-hour of charge delivered by the charger is accepted as one amp hour into the battery, hence the need to deliver a constant current as long as possible.

The Enerdrive ePOWER charger can be programmed for Lithium batteries. This setting delivers the full rated output of the charger constantly with the charger switching to power supply mode once the voltage peak is met (indicating a full battery bank). The graph shows the ePOWER charger algorithm perfectly supporting Lithium battery requirements.

The Display Panel

The ePOWER 20A Battery Charger display gives you all the information you need for the operation of your charger. At a glance, key information such as charger amps, battery voltage and charge state continually alternate on the screen.When in float / power supply mode, the load amps are displayed so you can see exactly what the charger is doing. The display also allows you to program all settings of the charger, as well as activate the silent mode.

Silence when you need it – By pressing the “SEL” button for 5 seconds, the ePOWER Charger enters the ‘Silent’ mode that prohibits the fan from working. This ensures totally silent and safe operation at night, ideal if the charger is located close to your sleeping quarters. Silent mode limits current output to no more than 50%, and is programmed to remain on for 12 hours before automatically returning to a normal ‘fan-on & full output’ setting.

CTEK Battery Chargers

CTEK was founded in 1997 and is a sister company of Creator Teknisk Utveckling AB (a leading design and development consulting firm), which was founded in 1982.

CTEK began developing its battery expertise as early as 1992, when a leading battery manufacturer hired Creator for battery research and development. The company was then hired to research a new system of battery chargers that would meet the charging and maintenance requirements of new generations of batteries.

The research and development programme ended when an American group purchased Creator's customer. Creator realised that the now patented system represented a fantastic business opportunity all over the world. It was then that CTEK was formed to design, develop, manufacture and market its own battery charger.

CTEK offers the market high-quality, reliable chargers and accessories that are effective, user friendly and, most importantly, safe (for the user, the vehicle electronics, the battery and the charger).
