Battery Systems

We have a range of DC to DC chargers, Low Volt Battery Cutouts and Smart Relays to suit a range of applications.

DC-DC Chargers vs Smart Relay Dual Battery Controllers

Newer vehicles (most manufactured after 2010) come with whats known as a smart alternator, or variable voltage alternator, as apposed to a fixed voltage alternator which comes as standard in older vehicles.

Fixed voltage alternators are becoming less common on new vehicles as reduced fuel consumption targets and stricter environmental and emissions standards are being followed by manufacturers. A fixed voltage alternator has a high enough voltage to charge a secondary battery in the vehicle to a usable level for leisure or auxiliary use.

The smart alternator system, also known as variable voltage alternators, allow the vehicle to control the output voltage and current from the alternator based on vehicle operating conditions. This is to reduce electrical load and in turn mechanical load on the engine by the alternator. Unfortunately, this renders it unsuitable for charging a secondary battery system to a usable level.

DC to DC Battery Chargers are Battery Chargers that gain there power from a DC Source such as your vehicle battery.

DC to DC Chargers are becoming more and more useful these days due to newer model car and truck alternators producing a much lower voltage then they used to, which is not suitable to charge deep cycle batteries to optimum levels.

The other commonly used scenarios are in Caravan / Campervan / Motorhome's to boost the voltage lost over long runs of cable from front of the car to the Caravan / Campervan / Motorhome's batteries. So by using a DC to DC Battery Charger you are able to boost this current to the correct voltage.

Enerdrive DC2DC 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 DC2DC 40+amp Battery Charger/ MPPT Reg

Designed to meet the rugged demands of Australian conditions and delivering multiple source charging for DC systems.

The Enerdrive ePOWER DC2DC+ Battery Charger is a fully automatic multistage, multi input battery charger with the ability to charge from either an alternator linked to a battery; or via solar power with the in built Maximum Power Point Tracking (MPPT) Solar Controller.

With two inputs available, the main/house battery will be charged from either the engine while underway, or via the solar panels when stationary. The process to choose either engine or solar is fully automatic and both functions are controlled from within the unit itself without the need for external relays.

During normal operation the ePOWER DC2DC+ Battery Charger will do a full charge cycle to float stage on the house battery bank with ability to choose either GEL, AGM, Flooded, Custom Programmable or Lithium. Once float stage is reached the charger transitions to a power supply mode to support any on-board DC loads.

The Enerdrive ePOWER DC2DC+ Battery Charger is a fully automatic multistage, multi input battery charger with the ability to charge from either an alternator linked to a battery; or via solar power with the in built Maximum Power Point Tracking (MPPT) Solar Controller.

Features:

• Two totally independent DC Inputs for both engine and solar regulation charging one house battery bank output
• DC M6 screw terminals that will allow for large battery cable connection between all sources
• A dedicated Maximum Power Point (MPPT) solar regulator
• The same battery algorithms as included in our AC mains ePOWER battery charger. GEL, AGM, Flooded, Lithium and the ability to create a full custom profile
• Vehicle input allows for either 12 or 24v and a maximum solar input of 45V/800W
• 40A+ output up to 40+°C with thermo controlled fan cooling
• Fully programmable LCD display to show which source is charging the battery along with charger status, voltage and amperage
• Temperature sensor included with charger for more accurate battery charging

Multistage Charging Process

The ePOWER DC2DC+ Battery Charger is a fully automatic, set and forget charger. It is designed to quickly and accurately recharge your deep cycle batteries utilizing charger algorithms that help to maximise the life of your specialised deep cycle batteries.

The ePOWER DC2DC+ Battery Charger features multistage smart charging technology that enables the charger to be connected to your battery bank permanently. With the input of multiple sources, you can be assured of charging your batteries whenever underway; or when the sun is shining on your solar array.

As dictated by battery manufacturer's recommendations, deep cycle batteries require a multistage charge sequence for perfect, fast and accurate charging. The Enerdrive ePOWER DC2DC+ smart charger delivers three 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 is recovered as fast as possible.

Stage 2 - Absorption Charge; With the charger voltage held steady, the remaining 20% is replaced with the charger allowing the current to taper off as the battery approaches 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, yet allows the charger to supply enough current to make up for the self-discharge losses of the battery, 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.

Smart Charging Feature

The ePOWER DC2DC+ Battery Charger will regulate its output based on the loads connected to your battery bank. This function is important to maintain the life of your battery bank as some battery chargers mistake loads for discharge and continue to keep the batteries in the bulk or absorption stage for extended periods of time, which will damage the battery bank. The ePOWER DC2DC+ Battery Charger has two methods of load based regulation to ensure your battery charger transitions to float when it should do so.

Intervolt DCC-Pro 25A DC-DC Charger

The DCC Pro In-Vehicle DC-DC Battery Charger was developed for the purpose of charging and maintaining any auxiliary battery in an installation where the starting battery is used as the supply source. It has been designed for use in 4WDs, RVs, buses, coaches, caravans, campers or any vehicle with a 12VDC electrical system.

The DCC Pro is built for our tough Australian conditions. Unlike many imported products, particularly those produced for the European market, it is designed to maintain output in the harshest of environments under the highest ambient temperatures.

The DCC Pro is a standalone power conversion device. It will manage a variety of different battery types according to their specific charging requirements.

Intervolt Inertial Sense Module

The Inertial Sense Module or ISM is a solid-state electronic device developed for use with the interVOLT DCC Pro.

In simple terms the ISM detects movement (from both engine vibration and acceleration) when attached to the vehicle chassis or body. Once the input voltage is within operating range this movement will provide a trigger signal to the DCC Pro and initiate the charging cycle.

This enables the DCC Pro to be operated in Ignition Mode without having to tap into the vehicle manufacturer's wiring system to obtain a signal. As a result, the whole DCC Pro install becomes totally independent of the vehicle's electrical system, aside from the common connection of the main battery terminals.

The ISM incorporates a short wiring harness (tail) which connects directly to the DCC Pro without any changes to the installation (if retrofitting) or any modification to the existing wiring harness.

The ISM is an over-moulded device rated to IP67 (dust and water proof) and can be fastened with the high-quality 3M tape included or via a single screw. Single screw fastening is recommended where vibration is minimal.

The compact size of the ISM allows it to be installed almost anywhere, within reach of the DCC Charging Device, of course. It is not recommended to extend the wiring harness but if Voltage Drop is factored in, it can be undertaken.

The ISM has a single LED indicator which will blink every 8 seconds in standby mode. Once activated by movement the LED will illuminate continuously until such time as the vibration/acceleration is no longer detected and the Voltage drops below the factory parameters.

Dual Battery Systems

In a boat or vehicle with two battery banks, it is useful to be able to charge both banks while underway. Charge management devices allow two battery banks to be charged from a single source, such as an alternator, but keep batteries isolated when not charging. If one battery becomes depleted, there will be a charged bank available for emergency starting.

Intervolt EBI12100A Electronic Battery Isolator 12v 100A

The EBI Pro is an electronic battery isolator aimed at replacing out-dated “electro-mechanical” type devices. Boasting features never before seen in dual battery isolators, the EBI Pro is designed to provide 4WD and RV users with real advantage and years of service.

Unlike conventional electro-mechanical isolators the EBI Pro is solid state. Solid state means no moving parts. There are no contacts to vibrate, chatter, arc, wear and ultimately - fail. The MOSFET based topology of the EBI Pro is proven. Reliability, durability and longevity are built in.

The solid state aspect is just the beginning. Designed on the back of the ground-breaking PSR, the EBI Pro is also adjustable in terms of voltage and time delay. This provides the installer or operator with the means to customise the EBI Pro for the application rather than suffer the ‘one size fits all’ philosophy from manufacturers of traditional devices.

These are expanded upon in greater detail in the manual but can be summarized as follows:

• Clear LED status display and indicators for ease of operation;
  
• 100 Amps continuously rated with a generous 500 Amps peak;
  
• Dual sensing allows main battery to be charged from auxiliary;
  
• Output indicator function for convenient in-vehicle monitoring;
  
• Input for in-vehicle remote emergency combine switch (starting);
  
• Overload and short circuit protection with automatic shutdown;
  
• Over temperature protected with automatic thermal shutdown;
  
• Low input voltage sensing with automatic shutdown protection;
  
• Electronics are encapsulated in dust and water proof housing;
  
• Compact design can be mounted in any position that suits;
  
• Heavy duty construction designed for under-bonnet installations;
  
• 24 months warranty (subject to policy terms and conditions).

Intervolt PSR Series DC Programmable Voltage Sensing Relays - PSR12150 & PSR24150

Voltage sensing relays have existed in one form or another for many years. They are commonly used to automatically replace the traditional manual process of controlling the charge function between batteries or battery banks, thus eliminating the risk of over/under charging.

interVOLT takes this process to a whole new level. The innovative design of the interVOLT PSR replaces traditional electro-mechanical relay devices used in 12/24 Volt DC applications by removing all mechanical parts to produce a completely solid state product with a myriad of added features.

In short, the PSR is a user adjustable voltage sensing relay in terms of voltage and time delay parameters. It allows the user to choose the voltage they want for switching loads on and off rather than be restricted to settings dictated by manufacturers. The time delay allows the relay to activate only after a user specified time to prevent cyclic (threshold) switching.

In addition the PSR is electrically isolated (contact to load), non-polarised and bi-directional, features previously unheard of in any other solid state relay devices. Additionally the PSR has the major benefit of being able to change from normally open or normally closed, all literally, at the touch of a button

The PSR can be used for a myriad of applications, including but not limited to:

• Combining of battery banks for charging and/or load sharing.
  
• Paralleling battery banks as emergency supplies.
  
• Switching loads at desired voltages both on and off.
  
• Protecting equipment from under-voltage supply.
  
• Isolating batteries at desired voltages both on and off.
  
• Safe and reliable remote switching of heavy loads.

Battery Low Voltage Disconnect

Low voltage disconnect switches are designed to protect batteries from excessive draw. Think of them as similar to circuit protection devices like fuses and breakers, but instead of terminating connection when voltage spikes, they disconnect when voltage drops too low, preventing damage to the batteries and load. To do this, a semiconductor switching circuit measures battery voltage; when it dips too low, predetermined auxiliary loads are switched off to ensure the battery has enough power left for engine starting.

This prolongs battery life by preventing damage due to excessive discharge and eliminates the need for separate timer or voltage sensing devices which simplifies wiring and installation and allows for a streamlined design.

The Smart BatteryProtect disconnects the battery from non-essential loads before it is completely discharged (which would damage the battery) or before it has insufficient power left to crank the engine.

When using Bluetooth to program the Smart BatteryProtect any required engage/disengage levels can be set.
Alternatively, one of nine predefined engage/disengage levels can be set with the programming pin (see manual)

If required, Bluetooth can be disabled.

The Smart BatteryProtect is a uni-directional device. It can only deal with current in one direction, so either current to a load, or current from a charger, but not both currents at the same time. In addition to this, current only can only flow from the IN terminal to the OUT terminal. In case of use with a load, the battery connects to the IN terminal, and in case of use with a charger, the charger connects to the IN terminal.

A special setting for Li-ion batteries: In this mode the BatteryProtect can be controlled by the VE.Bus BMS.
Note: the BatteryProtect can also be used as a charge interrupter in between a battery charger and a Li-ion battery. See connection diagram in the manual
