Secondly, the Orion li-ion BMS is a full-featured lithium-ion battery management system that is specifically designed to meet the tough requirements. Particularly, of protecting and managing battery packs for. Basically, there are three main types of electric vehicles EVsclassed by the degree that electricity is used as their energy source. To simply put, Battery Management System is the brains behind battery packs.

They manage the output, charging and discharging and provide notifications on the status of the battery pack. They also provide critical safeguards to protect the batteries from damage. The single most important function that a battery management system performs is cell protection. Lithium-ion battery cells have two critical design issues; if you overcharge them you can damage them and cause overheating. If the cells are discharged below this threshold their capacity can become permanently reduced.

If the protector detects that the voltage across the cells exceeds a certain limit, it will discontinue the charge by opening the Charge MOSFET chip. Once the charge has gone back down to a safe level then the switch will close again.

The second most important function performed by a battery management system is energy management. So, in practical terms, energy management is very important in portable electronic devices.

A battery management system tracks this capacity. Battery management systems for certain applications like the one for this hand-held point-of-sales terminal also include an embedded charger consisting of a control device.

Not forgetting, an inductor which is an energy storage deviceand a discharger. After all, the control device manages the charging algorithm. For lithium-ion cells, the ideal charging algorithm is constant current and constant voltage. A battery pack usually consists of several individual cells that work together in combination. If the cells go out of balance, individual cells can get stressed. Leading to premature charge termination and a reduction in the overall cycle life of the battery.

The cell balancers of the battery management system, extend the life of the battery by preventing this imbalance of charge in individual cells from occurring.We are starting a four-part series on our major electrical components. We will also go into detail about how we wired and set up each of these components.

We finally have everything in place to start testing things on our electrical system. It provides a brief introduction into what a BMS is and what it does. A BMS is important because batteries, especially lithium batteries, can be dangerous if not monitored. Everybody has heard about cell phones and laptop computers with lithium batteries catching fire or overheating. The risk for this type of event is increased many times over when the battery is overcharged or allowed to discharge further than it was designed to do.

When we first decided to experiment with these batteries, a BMS was the first thing we considered a "must have".

We rank it right up there with carbon monoxide and smoke detectors. As we shared in this previous postwe found two really great solutions for our battery. The first one was from Orion BMS and it seemed like a really solid product. The other was from REC. I think either of these two would have really been great for us.

I wrote each of them an email explaining our situation - what type of battery we are using, what inverters we are using, MPPT solar charge controllers etc. They were both very prompt and helpful with their responses, but the REC-BMS guys seemed more "in tune" with what we were doing. Their answers were much more specific and they just really went out of their way to fully answer my questions.

We will be tuning our parameters much lower with a max of 4. If the battery goes out of the parameters, the BMS will shut the battery off and sound an alarm. We want to tune them lower because we can get much, much more life up to 5X if we don't charge them to the absolute maximum and don't deplete them to the absolute minimum.

Monitors the temperature of the batteries. The BMS has 3 temperature probes in the batteries to gather this information. Lithium batteries cannot be charged if the temperature is below freezing. Balances the cells. The BMS will measure each cell as it is charging.

Cells that are at a higher Voltage than other cells will be balanced by discharging across a resistor. This is also tunable via software. BMS current measurement using a precision shunt resistor. Can protocol. Precharge circuit. Prolongs the life of our equipment by sending a trickle charge to components so that they don't get hit with the "in-rush" of current.

See: Wikipedia Article. Keep in mind that in our configuration of the Nissan Leaf modules, one "cell" is actually 14 smaller 33 Ah pouches wired together in parallel.

The temperature probes have a dedicated harness and plugin terminal. The Nissan Leaf modules have a great little space between the pouches to insert these probes.

Please see this video to see where we installed the probes. The shunt has a similarly dedicated harness to the temperature probes. Once we decided where the shunt was going to be mounted we cut the wire and installed new ring connectors to keep the shielded cable as short as possible.Magnetic Guide Sensors.

The Orion 2 BMS remains fully compatible with 12v applications.CAN stands for Controller Area Networkwhich is a protocol adopted by the auto industry to allow micro-controllers and other devices in a vehicle to communicate with each other.

Also shown at center right is the PLX Kiwi Bluetooth module, which will use CAN2 to transmit cell and pack data to a touchscreen that will be installed in the center console. The shielding wires on both CAN pairs should also be connected to chassis ground to eliminate any extraneous electrical noise that could interfere with clean data transmission.

Once successfully mounted, all of the tabs across the top of the window become active, and the utility is ready to start processing pack data. My first step is to populate the cell table using the setup wizard, which offers many different brand names, capacities, and quantities of cells. Once the charger brings the pack to a preset upper voltage, the Orion then sets about top-balancing the cells by slowly draining them to match the level of those least charged.

It does this even after the BMS has turned the charger off. As seen above, live data on cells that are balancing are indicated in red. Since this is their first charge with the Orion, most all of the cells are being balanced except the two lowest. I was informed by Ewert that the pack balance will tighten up after multiple charge cycles. From then on, the only reason to break out the laptop is to periodically check pack health, and to install firmware updates.

What a great relief to know that all my cells had dodged the fatal bullet of deep discharge. The Orion website offers instructions to coach you through this. Once loaded and locked to the BMS, Torque displays real-time pack data, with valuable logging and graphing functions. The above image is a screenshot from my drive into work this AM.

Thanks Leroy. It was great bumping into you. We could have talked much longer. You commitment to driving green is admirable. It will be a sad day when LAX takes away free parking for electric vehicles. The bluetooth transmitter has separate wires for signal path and power. Here is a link:. Any device should come with a diagram that shows which pins are signal, and which are power. I also purchased an opposite gender ODBII connector to plug into the MX, and soldered my power and signal wires to the pigtail that was already attached to that.
