VOLTstation® ES30 and ES50: Environmentally friendly energy storage for mobile use

The mobile energy storage system developed by Miba Battery Systems is an environmentally friendly alternative to conventional diesel generators.

 

  • Alternative to diesel generators on construction sites or at events
  • Two energy storage sizes available with 28 and 52 kilowatt hours
  • High discharge capacity for high power requirements
  • Premiere at the EES Electric Energy Storage trade fair in Munich from 14 to 16 June 2023

 

Laakirchen, 14 June 2023. Mobile energy storage systems can be used to meet the electricity needs of construction sites, open-air events and disaster control operations away from the grid infrastructure, thus eliminating the need for diesel generators, which pollute the environment with exhaust fumes and noise. Miba Battery Systems, part of the Miba Group, is now presenting the next generation of its VOLTstation® for the first time at the EES in Munich. The mobile energy storage unit can be used flexibly and is offered in two storage sizes.

 

With it, the Upper Austrian company is expanding its product range in the area of mobile energy storages. For applications with high energy and power requirements, the top version VOLTstation® ES50 is the suitable solution. The technical core is a lithium-ion battery with an energy content of 52 kilowatt hours. It provides up to 50 hours of power for appliances with low energy requirements - for example, for lighting or for operating refrigerators at events. If powerful construction machines are connected to the VOLTstation® ES50, they can be supplied with 20 kW of power, at peak times even up to 40 kW. A small crane on construction sites requires a power of 10 kW under load, a large concrete mixing drum with a volume of 750 litres up to 7.5 kW. Since not all consumers permanently call up this power and the electricity required for it, the capacity of the VOLTstation® ES50 is thus sufficient for a working day. A total of six Schuko sockets (16 amps, 230 volts) and two CEE plugs for 400 volts at 16 amps/three-phase are available as connections for consumers. Optionally, the connection panel can also be equipped with another CEE plug offering 400 volts three-phase at 32 amps. The battery can be charged via a Type 2 plug, as is also common in electric vehicles. This allows a charging capacity of 11 kilowatts, so that the battery can be fully charged in about five hours. Adapters can also be used for single-phase or three-phase charging at CEE sockets. The connection of PV modules is also possible via optional MC4 connections.

 

VOLTstation® ES30: Energy storage with 28 kilowatt hours of energy content

Another solution from Miba Battery Systems for mobile energy supply and thus decarbonisation is the VOLTstation® ES30. It is designed for all areas of application where predominantly moderate power peaks occur. The lithium-ion battery, also with NMC chemistry (nickel, manganese, cobalt), has a storage capacity of 28 kilowatt hours, which is enough for 30 hours of working time at low power demand and six hours at medium load. Two Schuko sockets (type F), single-phase, and two CEE sockets with 16 amps, three-phase, are available as connections for consumers. Each power outlet is individually fused. For charging, the VOLTstation® ES30 can be connected via a CEE plug with 16 amps three-phase as well as another single-phase. This allows charging powers of three or eleven kilowatts, so that the battery can be fully charged again in around three hours. The VOLTstation® ES30 also has two inputs for PV panels (MC4).

 

Compact dimensions, flexible use

Both the VOLTstation® ES30 and ES50 are compact in size with a maximum dimension of 1.60 x 1.10 x 1.50 metres. The larger energy storage unit weighs 670, the smaller 585 kilograms. This means that the storage unit can be flexibly transported on a small single-axle trailer. A class B driving licence is sufficient. This ensures that clean energy is available everywhere.
