Definitions

  • the invention relates to a truck-mounted concrete pump with an electric drive system with at least one electric drive designed to drive working components of the truck-mounted concrete pump, and a power supply unit with inputs and outputs for receiving electrical energy from at least two electrical energy sources and for delivering electrical energy to the electric drive. Furthermore, the invention relates to a power supply unit for supplying electrical energy to an electric drive for driving working components of a truck-mounted concrete pump.
  • the problem with an electrically driven truck-mounted concrete pump is that the electrical power provided by an on-board battery and/or a construction site power supply is not sufficient to electrically drive the truck-mounted concrete pump for the concrete delivery process sufficiently or for a sufficiently long period of time.
  • a truck-mounted concrete pump with the features of claim 1 and by a power supply unit for supplying an electric drive for driving working components of a truck-mounted concrete pump with electrical energy according to claim 12.
  • the power supply unit can ensure that the truck-mounted concrete pump is reliably supplied with electrical energy from the at least two energy sources. If, for example, the capacity of an accumulator connected to the power supply unit as an energy source is no longer sufficient to operate the truck-mounted concrete pump, the power supply unit can switch to a second connected energy source, for example a construction site power supply. On the other hand, if the construction site power supply is at the load limit, for example due to high current consumption by other consumers on the construction site, the power supply unit can switch to another energy source, for example an accumulator. In addition, the power supply unit can also connect the at least two energy sources in parallel, for example, in particular in the event that there is a high power requirement when individual aggregates of the truck-mounted concrete pump are started up.
  • the power supply unit is designed to take status data from at least one connected electrical energy source into account when controlling the consumption of electrical energy. Because the power supply unit takes status data of the connected energy sources into account, the power supply unit can control the consumption of electrical energy sources in a more targeted manner.
  • the status data relate to the type of electrical energy source connected. Because the status data relate to the type of energy source connected, it can take into account the type of energy source connected and thus distinguish between rechargeable and non-rechargeable energy sources, for example.
  • At least one of the electrical energy sources connected to the power supply unit is a rechargeable energy source, for example an accumulator, and the status data relate to the maximum available electrical power and/or the state of charge and/or the temperature of the rechargeable energy source.
  • the power supply unit can take this state data into account during the control and, for example, reduce the consumption of electrical energy from an energy source that is in danger of overheating or whose state of charge is only low.
  • at least one electrical energy source connected to the power supply unit is a mains power supply and the status data relate to the maximum available electrical power of the mains power supply. Because the power supply unit knows the maximum available electrical power from the status data of the mains power supply, it can take this into account when controlling the energy sources, for example to prevent an overload protection of the mains power supply from responding.
  • At least one electrical energy source connected to the power supply unit is a fuel cell and the status data relate to the maximum available electrical power of the fuel cell and/or the remaining electrical capacity.
  • the power supply unit can, for example, reduce the load on the fuel cell if the electrical capacity of the fuel cell is no longer sufficient for longer operation at full load.
  • the power supply unit is designed to make electrical energy available for charging a connected rechargeable energy source, for example an accumulator, by means of a further connected electrical energy source.
  • a connected rechargeable energy source for example an accumulator
  • the power supply unit can, for example, recharge an accumulator during a pumping break when little electrical energy is required for the pumping process, so that it can provide the electrical energy together with one or more energy sources for driving the truck-mounted concrete pump when there is a high current demand.
  • the status data of the electrical energy sources are transmitted via the inputs and outputs of the power supply unit. Because the inputs and outputs of the power supply unit are used for the transmission of the status data, the status data can be transmitted in a simple manner. According to an advantageous embodiment, the status data of the electrical energy sources are transmitted to the power supply unit via data interfaces that are different from the inputs and outputs of the power supply unit. This allows the status data to be transmitted to the power supply unit safely and independently of the connection of the electrical energy sources.
  • the electric drive of the power supply unit provides data on the electrical power requirement of the working components and the power supply unit takes into account the data on the electrical power requirement when consuming the electrical energy from the electrical energy sources.
  • the power supply unit can couple available connected energy sources at an early stage or, for example by activating a connected fuel cell, ensure that the electric drive of the truck-mounted concrete pump is not undersupplied.

If the energy requirement of the working components 107, 108, 111, 112 is low, for example during a pump pause, which the power supply unit 200 determines based on the current current consumption of the electric motor 122, the power supply unit 200 can, for example, absorb electrical energy from the electrical energy sources 120, 132, Control 133 so that current is passed from the site power supply 133 to the accumulator 120 in order to charge it.
