Abstract
A heavy-duty vehicle battery suspension system for releasably holding a rechargeable traction battery in an electric heavy-duty vehicle, wherein the heavy-duty vehicle battery suspension system comprises a pyrotechnical fastener, wherein the heavy-duty vehicle battery suspension system is configured to release the traction battery if the pyrotechnical fastener is triggered, and wherein the heavy-duty vehicle battery suspension system is configured such that the pyrotechnical fastener may be manually triggered. A method for releasing a rechargeable traction battery from an electric heavy-duty vehicle is also disclosed.
Claims17
A heavy-duty vehicle battery suspension system for releasably holding a rechargeable traction battery in an electric heavy-duty vehicle, wherein:
- the heavy-duty vehicle battery suspension system comprises a pyrotechnical fastener and a trigger device configured to trigger the pyrotechnical fastener by an electric potential by an operator connecting an electric cable of the trigger device to an electric energy source, a contact member arranged between the electric cable and the electric energy source for connecting the electric energy source to the electric cable;
- the heavy-duty vehicle battery suspension system is configured to release the traction battery if the pyrotechnical fastener is triggered;
- and
- the heavy-duty vehicle battery suspension system is configured such that the pyrotechnical fastener may be manually triggered by the operator.
A heavy-duty vehicle battery suspension system for releasably holding a rechargeable traction battery in an electric heavy-duty vehicle, wherein:
- the heavy-duty vehicle battery suspension system comprises a pyrotechnical fastener and a trigger device for triggering the pyrotechnical fastener, the trigger device being hidden during normal operation of the electric heavy-duty vehicle;
- the heavy-duty vehicle battery suspension system is configured to release the traction battery if the pyrotechnical fastener is triggered;
- and
- the heavy-duty vehicle battery suspension system is configured such that the pyrotechnical fastener may be manually triggered by an operator.
An electric heavy-duty vehicle comprising:
- a heavy-duty vehicle battery suspension system for releasably holding a rechargeable traction battery in the electric heavy-duty vehicle, wherein:
