REC BMS R&D has gone off-grid 🙂

November, 2019

Hurray, we finally found enough time to complete our Victron/REC BMS office installation. Our first system design for self-sustainability has come to life in our R&D office (yes, there are more to come soon). Victron EasySolar with integrated MPPT and circuit breakers makes perfect combination with battery pack controlled by REC BMS.

We love sunny days, so whenever possible we are charging our battery pack using only solar panels. Battery pack is composed of 16 in-series connected cells with nominal voltage of 3.2 V and capacity of 200 Ah, which makes about 10 kWh of energy; enough to run our R&D office through two working days completely off-grid and without sun power. Impressive?

Here are quick specs:

  • Victron EasySolar 48/3000/35 with MPPT 150/70
  • Polycrystalline solar panels
  • Battery pack: LiFePO4 cells (16 x 3.2 V, 200 Ah, total 51.2 V and 10 kWh)
  • REC BMS with all its accessories for control and “show-off”

Taking Care of Your Energy Storage in Winter

January, 2018

Winter time offers lots of winter joy, especially when there is a lot of snow fall. After each storm there is always sunshine :). The days are “shorter” and there is usually higher energy consumption and less green energy production, but nevertheless with proper handling your home storage system should function properly even during snowy winter.

If you have solar power plant on your rooftop, make sure it is not covered by heavy snow fall. If it is easily accesible brush it off with broom or some soft tool. Don’t use heavy tools or hard shovel, you may scratch or damage them permanently. In case your solar panels are on rooftop or not that-easily-accessible, don’t worry, the sun will take care of it by melting the snow from your panels on its own.

Extreme cold temperatures can be very hard on your battery pack. See the battery manufacturer’s datasheet for details of your battery behaviour during low temperatures charge condition. We don’t recommend to use fast charging at low temperatures, since the internal impedance of battery cells is much higher. If possible keep battery pack in a dry place indoors, with temperatures above freezing. Battery’s available capacity decreases with lower temperature (75 to 85 % of total capacity @ freezing level). Check system parameters frequently with LCD touch display for REC BMS or use multi-meter to check your cells voltage (if you are not using REC BMS). If you are not using your battery pack in winter time (e.g. hybrid/electric boat, summer cotage, etc.) it is best to charge the battery pack up to 50 % and disconnect it from the system. Don’t fully charge or discharge it, since the chemistry in this cases is more active and therefore it can shorten the battery life.

Enjoy winter time and promote reasonable energy usage.

Electric Car Conversion of SMART ForTwo 450

Postojna, Slovenia, August 2017

This summer REC Team with association of Metron Institut started a project of electric car conversion out of curiosity. We decided to use Smart ForTwo 450 with internal gas-combustion engine. Our mission was to GO GREEN and make an old car new again by converting it to electric vehicle. We have used powerful three-phase asynchronous motor from Mahle Letrika and LG Chem battery cells equipped with our state-of-the-art REC BMS Master-Slave configuration. The battery pack is located in a metal box at the very bottom of the vehicle where the battery space has already been provided in the original Smart design from 1998. Such position lowers the center of gravity and allows more stability of a car when driving. With cells configuration of 5P18S, we have managed to get the range of 160 km. We kept 6-speed gearbox fully functional as before, to make driving more enjoyable. To control the power and to keep track of all parameters, battery status and possible errors we have integrated our REC LCD touch display.

Quick specs:

  • Three-phase asynchronous motor (air-cooled Mahle Letrika AMV 7122 peak power 28 kW)
  • Motor controller (Mahle Letrika AEK1350 up to 450 A)
  • Chargers: TcCharger 6.6 kW
  • Battery cells: LG Chem 18 x 5 cells 3.7 V 60 Ah, total 66.6 V total 20 kWh
  • REC BMS Master-Slave configuration, with all its compatible components

Our version of service battery pack (12 V) in EV

Postojna, Slovenia, August 2017

Since we have put our electric converted car Smart to weight loss, we have made our own version of 12 V battery pack to replace the existing service lead-acid battery.

The 12 V lithium battery pack is comprised of 4 series connected cells, controlled by our state-of-the-art REC Active BMS (with active cell charge balancing). Compared to existing lead-acid battery we have managed to “slim” our Smart by 10 kg, which is 1.5 % of its total weight. Impressive?

Our customer experience with REC BMS

Germany, 13th of August, 2015

“I had been planning to develop and install a solar plant that fits the energy requirements of my household since months. The goal was to make the own power consumption of solar energy as high as possible.

On April 7th this year my plant started to generate energy from solar radiation. At this time the installation consisted only of panels with a total power of 3,64kWp and the inverter (SMA Sunny Boy 3000TL-21). Knowing the power pattern consumption of my household it was clear that I have to extend my installation with some kind of energy storage to reach my goal. After some calculation and reading I decided to build an energy storage on my own. My first decision was the battery inverter (SMA Sunny Island 3.0M-11). I have chosen SMA because the charging/feeding algorithm is well developed and the Sunny Island works very good together with the Sunny Boy/Home Manager.

The next thing was finding the right battery/cell. For this I defined some conditions: temperature range -15°C up to +45°C (energy storage will be located in a none conditioned environment), lifecycle > 10 years, no liquids inside the cell and fast charging. This conditions led me to the Winston/Thundersky LiFeYPO4-cells. The advantages of these cells are: wide temperature range in charging/discharging mode, charging with 0,5C, >5000 cycles. But these cells are very very sensitive regarding the cell voltage. Exceeding or underrunning the voltage limits will damage the cell.

At this point the REC BMS was coming up. I’ve read on internet user forums, that a guy from Norway built an energy storage with used Li-cells from a Nissan Leaf, SMA Sunny Island and a BMS from a Slovenian company called REC. That was exactly what I searched for! A BMS that communicate important parameters, like max charging current and cell voltage, with the Sunny Island.

Ordering the BMS and delivering it to Germany worked like a charm. I received the BMS 9R preconfigured with the right settings and a firmware update. Installation and configuration was very easy.

I finished my work on July 19th this year. The result is an energy storage with 5,7kWh (C10, 100%) overall capacity. The storage consists 15 cells Winston LYP100AHA. With this storage I have reached my goal (at least in summer). From July 19th until the time of writing this article I have only bought 1kWh energy from my utility company (thanks to this perfect summer!).

Let’s see how it works in winter, I’m curious.”

First Cross Country flight in SUNSEEKER DUO:

Milano, June 21st, 2014

“Irena and I just returned from an overnight trip in our new plane, our first experience traveling in it. We set our goal to be easy, only 100 miles away, and in the conditions we could have flown twice that far, both ways. Climbing over the clouds on our way, we enjoyed a tailwind at altitude, and arrived in less than 3 hours.

We had to chose over the clouds or under, and flew some of each. Over the clouds is smooth air and full sun for the solar panels, but our path could be blocked by towering cumulus, that we could not climb over. Under the clouds we were likely to encounter turbulence, downdrafts, lots of shadows and high terrain, so we tried to stay on top as much as possible. Better conditions for a solar powered airplane.

On the radio we quickly located of host Gianluca, who was flying a Duo Discus sailplane with a student under the clouds. After flying with him for a while, we decided to go explore the high peaks to the south, which still have some snow in mid-June.

Landing at Pavullo was easy, and familiar to me, as I had landed here in 2009 in the single seat SUNSEEKER. The next morning we awoke to strong NW winds, that would be a headwind to get home. We bought some fruit and decided to try to make the flight back against the wind. The air was turbulent in the area of the airport because of the wind, but after we gained some altitude it was smooth sailing, and we made the flight back home in 3 hours despite the headwind. Since it turned out to be so easy, we continued on toward Genoa, hoping to get a nice view of the sparkling Mediterranean, but it was covered in low clouds. Still we had some nice local flying and saw two other gliders in the air.

Irena landed the SUNSEEKER DUO back at Voghera without problems, despite the turbulent air.”
