Embodiment Construction

[0040] figure 1 The main elements of a battery housing 1 are shown schematically, including a battery 2 and a connection device 3 . The battery 2 comprises a first terminal 2a and a second terminal 2b and several accumulator blocks (not shown). For example, the accumulator block takes the form of an isolating seal containing the electrical energy storage block assembly and is mounted in series between the first terminal 2a and the second terminal 2b of the battery. For example, the first terminal 2a may be the positive terminal of the battery and the second terminal 2b may be the negative terminal of the battery.

[0041] The battery 2 is connected via connection means 3 to one or more circuits of the motor vehicle, for example electric propulsion circuits, electric shock absorber circuits, electric air conditioning circuits and the like. In particular, the negative terminal 2b of the battery may be connected to a common negative terminal 4 of the circuits, and the positive ...

Abstract

The invention relates to a device 3 for connecting a battery 2 to an electric or hybrid motor vehicle, comprising at least one input 3a that can be connected to a terminal of the battery and an output 3b that can be connected to a first terminal of an electric circuit of the vehicle. The device 3 further comprises a circuit breaker 8 mounted in series between the input 3a and the output 3b of the connection device 3. The circuit breaker 8 comprises a pyrotechnic ignition connected to control terminals, tripping of the circuit breaker 8 being controlled by an electric control signal applied to said control terminals. The invention also relates to a battery housing 1 comprising a battery 2 and a connection device 3.

Description

technical field [0001] The invention relates to the field of motor vehicles of the electric or hybrid type requiring the use of batteries. In particular, the invention relates to the field of battery connection devices in motor vehicles. Background technique [0002] "Electric Vehicle" means a vehicle as defined in the United Nations Regulation No. 100 Standard for Battery Powered Electric Vehicles. [0003] In order to provide vehicles with increased driving range, large amounts of stored electricity are required. This results in the use of relatively bulky, relatively bulky batteries and may be risky from an electrical point of view. [0004] As is well known, "passive" fuses are used in practice to isolate electrical components when they carry a current higher than a value determined by the characteristics of the fuse. So the fuse operates like a kill switch. Fuses, however, only react to electrical current and are not capable of isolating electrical components in the...
