Abstract
In a power storage pack, a power storage unit feeds electric power to an electric moving body. A controller superimposes a current pattern representing identification information of the power storage pack on electric power to be supplied to electric moving body. The controller generates a current pattern with current values of a plurality of levels other than zero level. The controller may superimpose a current pattern on electric power supplied to an electric moving body through a precharge circuit.
Claims8
A power storage pack comprising:
- a power storage unit for feeding electric power to an electric moving body;
- a controller superimposing a current pattern representing identification information of the power storage pack on electric power to be supplied to the electric moving body;
- a power line, inside the power storage pack, connecting between the power storage unit and a power feeding terminal;
- a main switch inserted into the power line;
- and
- a precharge circuit connected in parallel with the main switch,
- wherein the controller generates the current pattern with current values of a plurality of levels other than zero level and superimposes, while the main switch is off, the current pattern on the electric power to be supplied to the electric moving body through the precharge circuit.
