Problems solved by technology

[0006] Nevertheless, in the event of failure of the internal insulation of a supercapacitor module, a short circuit to ground with very high currents can result, which can lead to complete destruction of the module and can release dangerous or even toxic gases in the environment around the module

Embodiment Construction

[0026] figure 1 In the example, an energy storage system 10 is mounted on a railway vehicle and connected to a power converter 12 . The power converter 12 is, for example, a voltage chopper mounted on a railway vehicle and adapted to be connected to an overhead line. The chopper 12 is particularly suitable for reducing the voltage of the current flowing in the overhead line in order to provide a continuous rated operating voltage Uin applicable to the input of the energy storage system 10 . The value of voltage Uin is, for example, approximately equal to 400 volts.

[0027] The energy storage system 10 has an energy storage chain 14 according to the invention and an electrical connector 15 connecting a voltage chopper 12 to the energy storage chain 14 . The energy storage system also has a high voltage disconnection device 16 , such as an automatic disconnect switch, which is connected to the chopper 12 and to the energy storage chain 14 via an electrical connector 15 .

Abstract

The invention relates to an energy storage chain for a vehicle, including at least one ultracapacitor module, an energy storage system and a railway vehicle. The chain (14;55;56;60) has a metal frame (24),an electrical storage system (26) mechanically fastened in the metal frame (24), and comprises at least a supercapacitor module (32A-34A) and at least an electrical protection device (28) used to disconnect the circuit. Each of the supercapacitor modules (32A-34A) comprises a metal enclosure (36) and a set of supercapacitors (40) linked together in series and arranged in the metal enclosure (36). An electrical protection device (28) comprises a fuse, and is designed to open an electrical circuit. The electrical protection device links an element out of the metal frame or the supercapacitor modules (32A-34A), to an electrical ground.

Description

technical field [0001] The invention relates to an energy storage chain for a vehicle, comprising: [0002] -metal frame, [0003] - An electricity storage system mechanically secured within a metal frame and comprising at least one ultracapacitor module, the or each module having a metal housing and a plurality of supercapacitors arranged within the metal housing and connected to each other in series. Background technique [0004] Such an energy storage chain is especially suitable for recovering and storing the energy of the braking system of vehicles, especially railway vehicles traveling in the network. The energy storage chain can be fixedly installed at a fixed location in the network or mounted on a certain railway vehicle, in both cases the energy is stored in the supercapacitors of the or each module of the chain. [0005] Such a storage chain often has a network of supercapacitor modules connected in series in order to obtain a significant energy reserve for the...
