Abstract
A magnetic brake mitigation module is described. During a catastrophic failure of a power supply, magnetic brakes are designed to quickly bring an electric vehicle to a stop. In some electric vehicles with minimal safety systems (e.g., seatbelts or doors), the abrupt stop can be unsafe. The magnetic brake mitigation module determines when a catastrophic failure has occurred and supplies, for a short period, stored power to the magnetic brakes to prevent a maximum braking force from being applied to the wheels.
Claims12
An apparatus comprising:
- an analog-to-digital converter configured to be attached to a battery and output a first digital signal representing a voltage across battery terminals of the battery;
- a power storage device;
- a voltage regulator configured to receive power from the battery and output power to the power storage device;
- a power switching circuit configured to receive power from the power storage device and output power to a magnetic brake of an electric vehicle;
- and
- a hardware controller configured to:
- receive the first digital signal;
- determine, based on the first digital signal, whether the voltage across the battery terminals is below a first threshold;
- and
- control, based on a determination that the voltage across the battery terminals is below the first threshold, the power switching circuit to transmit power to the magnetic brake.
