Abstract
A vehicle battery apparatus is provided for a vehicle having redundant batteries and a reverse polarity protection circuit associated with each battery. The vehicle battery apparatus comprises an isolating circuit coupled between the reverse polarity protection circuits and a load that can be powered with forward current flow from the redundant batteries through the reverse polarity protection circuits. The isolating circuit is arranged to prevent reverse current flow through the reverse polarity protection circuits to the redundant batteries.
Claims22
A vehicle battery apparatus for a vehicle having redundant batteries and a reverse polarity protection circuit associated with each battery, the vehicle battery apparatus comprising:
- an isolating circuit coupled between the reverse polarity protection circuits and a load that can be powered with forward current flow from the redundant batteries through the reverse polarity protection circuits, wherein the isolating circuit is arranged to prevent reverse current flow through the reverse polarity protection circuits to the redundant batteries.
A vehicle battery apparatus comprising:
- first and second batteries;
- first and second reverse polarity protection circuits associated with the first and second batteries, respectively;
- and
- an isolating circuit coupled between the first and second reverse polarity protection circuits, wherein the isolating circuit allows forward current flow from the first and second batteries through the first and second reverse polarity protection circuits and prevents reverse current flow through the first and second reverse polarity protection circuits to the first and second batteries.
A vehicle battery apparatus comprising:
- first and second batteries;
- first and second reverse polarity protection circuits associated with the first and second batteries, respectively;
- and
- means for preventing current flow from each battery through the reverse polarity protection circuit of the other battery when the other battery is disconnected from its associated reverse polarity protection circuit.
A method of operating a vehicle battery apparatus having at least two batteries and a reverse polarity protection circuit associated with each battery, the method comprising:
- preventing current flow from a first battery through the reverse polarity protection circuit of a second battery when the second battery is disconnected from its associated reverse polarity protection circuit.
