Claims25
An energy storage device (3) for storing electric energy for a partial or complete electric drive of a vehicle, comprising:
- energy storages (1) and power storages (2), wherein an internal resistance of the energy storages is larger than an internal resistance of the power storages, and
- a current regulator (4) which limits a current flowing between the energy storages and the power storages, wherein the current flow is controlled by the current regulator (4) in dependency of a current strength.
A method for operating an energy storage device (3) with energy storages (1) and power storages (2), comprising:
- a current flow between the power storages (2) and the energy storages (1) is limited by means of a current regulator (4) and the current flow is limited such, that it remains within a tolerance band (9) and that a cooling of the energy storages (1) is not necessary.
An energy storage device (3) for storing electric energy for a partial or complete electric drive of a vehicle, comprising:
- energy storages (1) and power storages (2), wherein an internal resistance of the energy storages is larger than an internal resistance of the power storages,
- a current regulator (4) which limits a current flowing between the energy storages and the power storages,
- a drive unit, and
- at least one electric machine (12) provided as a motor (11) or as a generator (11), wherein the current flows from the energy storages (1) via the current regulator (4) to the electric machine (12).
