With over 1200 complete systems in operation Australia wide, Enerdrive is regarded as the leader in the field of lithium batteries and energy systems for Mobile, Marine and Remote applications.

The ePOWER Industrial Battery Charger is available in three output voltages, 24V, 36V and 48V for usage in applications such as electric vehicles, fork lifts, floor cleaning machines, golf carts, and electric mobility scooters.

Enerdrive’s ePOWER Industrial Battery Charger is built to withstand vibration and exposure to dust or moisture typically found when used in typical on-board or industrial applications. Charge Algorithm updates and downloadable charger data logs are easily accessible via the use of a USB memory stick.

• Extremely Durable. A fully sealed die cast aluminum enclosure protects the charger from fluids and other contaminants. The design of the charger enclosure mirrors the internal components, protecting against shock and vibration.
• Programmable Charging. A USB host port allows for charger data logging downloads and charge algorithm uploads using a commonly available USB flash drive. This information can be used by OEMs to improve products, limit battery warranty claims and help technicians with troubleshooting issues.
• Battery Charging Flexibility. With over 25 algorithms to choose from that suit 90%+ of the batteries on the market today, the ePOWER Industrial charger also has the ability to create full custom algorithms to suit any type of lead acid battery. The charger is optimized to provide precise battery charging of different battery chemistries and battery manufacturers. These charge profiles allow charging to occur quickly and carefully, maximizing battery life and performance.
• *NB: Lithium Programming - May be programmed to charge Enerdrive Lithium batteries only - Must be factory programmed at the time of purchase with an Enerdrive Lithium battery system

B-TECH Parallel Tech Note (from Enerdrive)

Paralleling of B-TEC Batteries – As you may be aware, Enerdrive have long been against the Paralleling of Internal BMS batteries. This has been from the experiences we have had and seen over the last 8 years of using Lithium’s in a commercial capacity. Although the Batteries may be able to be connected in Parallel, these batteries are not always sold with taking the application into account. From our experience due to the very low voltage difference of a lithium battery between full and 20% SOC underload. When 2 batteries are in parallel, the power doesn’t always pull evenly from each battery as the battery with the higher voltage (Lower Internal resistance) will deliver the power. For this reason, each BMS needs to be capable of handling the full load of the system. An example of the is; If 2 x 100AH Lithium batteries with an internal BMS that can handle 100A each are put into a system, the max load on the system should still be only 100A.

Both Scenarios below assume 2 x 100AH Lithium with a BMS rated to 100A each.

Scenario 1: The Consumer only runs a fridge, lights, TV and a 1000w inverter for the odd thing. They never exceed 100A load and don’t run the batteries flat. They may never have or see any Issues.

Scenario 2: The Consumer sees they have 200Ah of lithium and decide to connect a 2000w Inverter, which running at full load can be drawing approx. 180A from the battery bank. Effectively the load will not pull evenly off the 2 batteries, 1 BMS will always switch OFF before the other putting all the load on the remaining BMS, which at 180A will overload. So when the Batteries shut down like this (never simultaneously) , the Inverter will try to pull power from the remaining battery. The overloaded BMS (remaining battery) will be over run and ultimately fatigue, causing premature failure.

Normally the only place that still has power would be the solar controller output which would then inject unfiltered power into the inverter before the inverter shuts down due to a lack of power. When this occurs, in the milliseconds it takes the solar controller to realise it has no place to go, it may spike the system with solar voltage slowly damaging other equipment. By using a single Enerdrive 200AH B-TEC with the internal BMS capable of 200AH, you can then safely run your 2000w inverter without overloading the BMS. The same goes for the 200AH B-TEC, if running 2 in parallel it does not mean you can run a 3000W Combi. Due to Enerdrive not being able to know where every battery was going and into what application we decided to make a commercial decision to just do a blanket no paralleling policy for the B-TEC batteries and instead recommend people use a single battery capable of the task at hand. We still recommend this approach for internal BMS batteries, but if the installation has been deemed appropriately suited to parallel batteries (loads not exceeding rating of 1 BMS) then you will also need to be aware of the following things.

• Each battery should be charged to full separately first and left 1/2 Hr to rest and a max 0.2V difference between the batteries before connecting together (this will make sure the batteries are as close to being balanced at the start)
• Parallel cables between the batteries shall be at least the size of the Main battery cables but the larger the better.
• When connecting the Main battery cables you must make sure you cross wire the Battery Bank. .i.e. Positive to first Battery in the Bank, Negative to the last battery in the Bank (see diagram below)
• The Enerdrive B-TECH Bluetooth App (available for Apple and Android Systems) will only show 1 battery in the bank at a time and the batteries may get slightly out of sync. So make sure that you watch each battery and make sure you don’t take any one battery below its cut-out point.
• If you notice the SOC% of the batteries getting more than 10-20% out of sync, the Batteries should be separated and charged separately back to 100% and then reconnected (see first Point) to maintain the capacity of the overall Bank.
• DO NOT exceed the load limits of a single BMS.
• We also recommend that an external SOC% battery monitor is fitted for overall battery bank capacity and connect this to a Low Battery Cut-out to shut loads OFF at around 20%SOC to prevent taking any battery to its cut-out point.

For large systems that use Inverter/Charger Combi units, have large solar arrays and for people wanting to run Air-conditioning, Enerdrive still recommend upgrading to the Enerdrive White Pro Series that not only looks after the battery but the whole system by shutting down charging systems via each unit rather than just isolating the path to the Cells and also isolate loads while still allowing Chargers to access the battery. The external component approach to the White Pro systems BMS allows for infield Fault finding, service and the ability for the Enerdrive Tech team to get you out of trouble if the need arises. Other benefits of the Enerdrive White Pro System is less individual Cells, Active Balancing, Heavy duty components and a 5year Warranty that extends to the supplied Enerdrive Charging equipment and backed up by Enerdrive’s renowned Tech Support.
