Daimler starts deliveries of Mercedes-Benz energy storage units for private homes

Tesla Motors isn’t the only game in town when it comes to re-branding automotive fame into the energy storage business.

Daimler has also announced the start of deliveries for its home energy storage systems produced under the Mercedes-Benz brand by subsidiary Deutsche ACCUMOTIVE.

Initially, Daimler entered into the ESS for business and utility companies; today, private homes is the next logical step in leveraging its advantage from developing battery packs for cars.

In case of Daimler, a ‘single block’ stores 2.5 kWh, and up to eight units and be connected for a total of 20 kWh.

Sales through a nationwide network of sales partners, and partner companies, has begun in Germany and will soon be expanded internationally.

Harald Kröger, Head of Development Electrics/ Electronics and E-Drive Mercedes-Benz Cars said that there is “tremendous interest in our energy storage units and we have already received numerous orders“. Most of the private homes customers intends to have ESS with photovoltaic system.

“Stuttgart/Kamenz – Daimler AG has commenced deliveries of Mercedes-Benz stationary energy storage units for use in private homes. The lithium-ion batteries are being manufactured by the Daimler subsidiary Deutsche ACCUMOTIVE and distributed through selected sales partners and partner companies. At present, the company’s partners include the energy service provider Energie Baden-Württemberg (EnBW), the solar technology specialist SMA, as well as a number of wholesale traders. Their network of qualified specialist installers take care of providing the end customers with on-site advice, planning, compiling an individual quotation for all components and the actual installation. Stationary battery storage units are generally installed together with a photovoltaic system. Some 500 installers throughout Germany have already undergone training in collaboration with the partners.”

From cars to power grids: Mercedes-Benz energy storages are also suitable for private use to buffer surplus power virtually free of any losses.

From cars to power grids: Mercedes-Benz energy storages are also suitable for private use to buffer surplus power virtually free of any losses.

“Originally developed for the rigorous demands of automotive operation, the Mercedes-Benz energy storage units meet the very highest safety and quality standards. Up to eight battery modules with an energy content of 2.5 kWh each can be combined to produce an energy storage unit with a capacity of up to 20 kWh. Households with their own photovoltaic systems can therefore buffer surplus solar power with virtually no losses. By combining renewable energy sources with a local battery storage unit, private households can increase their self-consumption of generated energy to as much as 65 percent, thereby bringing about their own “private energy revolution”.

The retail price for home electricity generation is calculated based on a customised package of system components. These may comprise the photovoltaic system, battery inverter, energy management and the Mercedes-Benz energy storage unit, plus the cost of installation. “We can count on the support of expert partners for our sales of the Mercedes-Benz energy storage units. The ideal contact for the end customer is their local electrical specialist. We are convinced we can offer our customers an attractive product at a competitive price,” says Kröger. Besides consulting a qualified specialist company, customers also have the option of placing their order directly with Mercedes-Benz (www.mercedes-benz.com/energiespeicher).

Daimler AG: systematic expansion of the battery storage business

Daimler AG entered the stationary battery storage business in 2015 with its subsidiary Deutsche ACCUMOTIVE and has been continuously expanding its activities in this growth segment ever since. The concept devised by Daimler Business Innovation provides for a variety of applications. The systems are scalable, meaning that the lithium-ion battery units can be employed both in large-scale industry and in private homes. Three major projects centred on industrial energy storage solutions are already under development. Eventually, battery modules with a total capacity of over 29 MWh will be connected to the grid as part of this and marketed on Germany’s primary energy market together with specialist partners. The storage units serve to balance energy fluctuations in the German national grid. Further projects are already planned.

The stationary energy storage sector presents Deutsche ACCUMOTIVE with new opportunities for growth. In addition to this, Daimler AG is playing an active role in the energy revolution and continuing the success story of battery manufacturing in Germany. Daimler is systematically increasing its production capacities and investing some €500 million in the construction of a second battery factory at the Deutsche ACCUMOTIVE site in Kamenz. The new facility is due to be put into operation in summer 2017.

  1. Tesla is out of the European storage battery market. Should better not even try it here, they will burn more money only.

    1. Speculawyer says:

      Tesla has a better use for their batteries: cars.

      1. Get Real says:

        Yes, Tesla will be making and installing many more KWHs of batteries then the competition that they will soon have a serious price advantage but the vast majority of the batteries will go into the hundreds of thousands of cars that Tesla will buy.

        1. Get Real says:

          Damn auto-correct, was supposed to be sell not buy.

          1. sven says:

            Why would auto-correct change sell to buy? It sounds more like human error or perhaps a Freudian Slip. 😉

    2. beta995 says:

      Tesla has enough business in CA, and Australia right now.

      But, Thanks Tesla, for waking Mercedes up.

    3. TomArt says:

      There is no requirement, nor reasonable expectation, that Tesla Energy would have to operate at a loss. It’s just a battery pack with a management system – there is no car surrounding the battery, no additional stores or service centers needed, nor does this business require additional superchargers. And, the cell R&D is shared with Tesla Motors! As long as the demand is there, this is a low-risk, low-cost spinoff of their automotive business.

  2. Trollnonymous says:

    I’m not sure how effective these would be.
    If you have a Solar array sure, it should be able to store energy for use later or kick in when the sun goes down.
    Other than that, the ROI seems to not be in your favor.

    1. V. Bowman says:

      Yes…and that’s exactly who they are marketing to… those with a solar photovoltaic system. Why else would you purchase a storage battery unless you were ‘making’ electricity? This is entirely the point.

      1. ericonline says:

        They may also be useful for areas where power outages are common. Hurricanes, tornadoes, tropical storms etc. wreak havoc on those of us who live on the gulf coast. It would be nice to have a couple days of energy stored away instead of relying on a natural gas generator.

        1. Speculawyer says:

          Yep. This will catch on. But right now the equipment for setting up a system that does, charging, islanding, battery management, etc. Is not very good or cheap. But it WILL get there. SolarEdge’s StorEdge is pretty good. But I am content to wait for the equipment to improve.

    2. missdeborah says:

      Interesting…For sure….

    3. beta995 says:

      Have you checked the size of your utility no power charges?
      You’ll pay off the battery in 10 years by going off-grid.

      1. mr. M says:

        To go offgrid in Germany around 200-300kWh of battery are required to fill the huge summer/winter difference.

  3. Speculawyer says:

    Home batteries can make sense in Germany where their electricity is very expensive and they reduced the FIT. The battery allows you to self consume your cheap PV electricity instead of buy expensive grid electricity.

    But batteries don’t make sense in the USA except for Hawaii.

    1. acevolt says:

      Batteries might make sense in the US if you want to time shift. I pay $.50/kWh during peak and $.11/kWh during super off peak. If I moved my $.50/kWh useage to $.11/kWh usage that would save $.39/kWh. So a 6kWh system in California would save you $854/year if you are going to use 6kWh during peak periods every day of the year.

      1. BA says:

        Yes. But if you have a PV system, you generate energy during the peak time, and if you send it along to the grid, you get credited at that rate, which buys almost 4 times as much in the super off peak, when it is good to charge cars.

        1. Mike I says:

          I have the EV rate plan from PG&E in California and the Summer Peak rate of $0.444/kWh goes from 2pm-9pm. I consume more power in the evening than my solar can generate after 2pm, so a battery storage system to shift my usage would significantly reduce my bill. I have not calculated exactly how much I could save per year by completely shifting that usage.

      2. Leeper says:

        Holy hell! You pay $0.50 per kWh peak? I just signed up for $0.07 with no time of day charge. Fixed for 3 years. One of the benefits of living in Ohio I guess .

        1. Speculawyer says:

          It is a progressive rate. The first X kwh are 0.12, the next Y kwh are 0.18, and so on. 0.50 is only superpeak for energy hogs. California has a good rate system that incentivizes people to be efficient. And it incentivizes people to get solar PV.

    2. beta995 says:

      You’d better check your utility customer( non-power ) charges.
      You’ll pay off the battery in 10 years by going off grid.

    3. sveno says:

      Batteries and PVs also make sense in rural areas where you would have to pay for power line installation.

    4. sven says:

      Speculawyer said:
      “But batteries don’t make sense in the USA except for Hawaii.”

      Tesla confirmed this in their response to an Engadget article that reported on a Institute for Energy Research (IER) study which concluded that it would take 40 years for a Powerwall to pay for itself when your TOU peak rate is $0.15/kWh and off-peak rate of $0.06. Tesla said the payback calculation was correct for that rate structure, but that the Powerwall provides non-econonmic benefits. Tesla also said “that regions with renewable-energy policies like feed-in tariffs — such as Hawaii, the UK and Australia — provide a more accurate basis for the Powerwall’s use in the wild.”

      Oddly, Engadget cow-towed to Tesla and claimed that the IER had a politcal bent, and that it’s study was flawed, does not represent real-world conditions, and deals with misleading data. Then Engadget apologized to its reader for taking this report at face value!

      I read the IER’s report, and their analysis was fair and evenhanded. Engadget refused to publish the IER’s response/rebuttal to Tesla’s claims, and only gave a link to their response/rebuttal.

    I don’t see why some are hostile towards Mercedes. If anything I congratulate Mercedes. I also hope that BMW does the same. It is a shame that GM and Ford are not doing that that yet. The sooner we get rid of oil the better.

    1. Speculawyer says:

      Oh, I think it is great. The more batteries, the more battery research, refinement, battery electronics, mass manufacturing, lithium supplies, etc. Grow that market!

  5. D says:

    I also applaud Mercedes for investing in batteries.

    I wonder, however, what the price for those 2.5kwh modules is.

  6. wavelet says:

    Strange that they’re doing this under the Mercedes label.
    Unlike Tesla, Daimler is a large engineering company that does plenty of things outside of cars. I suspect this means these will be very expensive systems…

  7. Nemo says:

    Why only 65%? Seems arbitrary.

  8. jmac says:

    There is increasing blow back from utilities who don’t like net metering and don’t want to buy back PV. The issue is that PV households are not paying their fair share of taxes to maintain the utility transmission lines, transformers, etc.

    Under net metering the utilities have been buying electricity from grid tied PV customers at maximum daytime rates but are selling back grid electricity at reduced evening rates.

    The Nevada legislature recently ended net metering in Nevada, taking away virtually any incentive to install a solar system in Nevada. The people that did this are not trolls, but clean cut guys in business suits that wined and dined and bought off the legislature.

    The bottom line is that renewables such as wind and solar badly need a means of storage. The backlash from utilities that wish to maintain central control of electric distribution will likely grow.

    So, I’m glad to see Tesla and Mercedes stepping into the breach. Affordable solar storage is exactly what we need. It’s odd that two car companies have become involved in this, but then everything is being turned upside down as energy use shifts away from fossil fuels.

    1. TomArt says:

      Well, it doesn’t have to be that way. My electric bills here in VA have always been divided up in two portions: 1) energy generation and associated fees, and 2) distribution and associated fees.

      The mistake is that both are calculated as percentages of electricity consumption. The distribution charge should be a fixed rate for everyone connected to the grid, and then the generation portion should be based on usage and subject to net metering.

      1. mr. M says:

        Yes, that is the best way to do it. It’s the same in Germany.

        I pay around 9€/month for Transmission and being connected and 60€/month for getting current.

    2. a-kindred-soul says:

      I don’t think it’s odd that car companies go into battery storage. Car batteries that go below 80% capacity cannot be used for cars anymore, but are perfectly suited for storage. In fact, their capacity loss in % per year will slow down when they grow older.

      Just don’t tell the client they are getting 80% capacity batteries. Clients just need to know the capacity in kWh and the (low) capacity loss.

  9. angelo festa says:

    Training for patience one needs if you´re waiting for a TESLA 3, can be garnered by ordering a powerwall on Day One of it´s announcement of availability. Mr Musk hardly got the words out of his mouth, when my order was accepted. I´ve written 4 emails asking when is it coming. Top date, no replies to any of the emails. Any of you had better luck getting a response from TESLA?

    1. mr. M says:

      The powerwall is only available for electricians or ask a solar installer. However the stated price of musk can not be accieved. You will pay 6000$ Minimum.
