Abstract
Controller (12) of power storage pack (10) communicates with controller (32) of electric moving body (30) in a state where power storage pack (10) is mounted to the electric moving body. Communication wiring (Lc1) connects a node of power line (Lp1) on power source terminal (Tp) side relative to first switch (RYp) and controller (12) of power storage pack (10). Overvoltage protection circuit (19) turns off second switch (SWc) inserted into communication wiring (Lc1) upon detecting an overvoltage of power line (Lp1) during communication between controller (12) of power storage pack (10) and controller (32) of the electric moving body.
Claims8
A power storage pack comprising:
- a power storage unit for supplying power to an electric moving body;
- a power line connecting between the power storage unit and a power source terminal for charging and discharging;
- a first switch inserted into the power line;
- a controller that communicates with a controller of the electric moving body in a state where the power storage pack is mounted to the electric moving body or communicate with a controller of a charging device in a state where the power storage pack is mounted to a charging slot of the charging device;
- a communication wiring that connects between a node of the power line closer to the power source terminal relative to the first switch and the controller of the power storage pack;
- a second switch inserted into the communication wiring;
- and
- an overvoltage protection circuit that protects the controller of the power storage pack from overvoltage,
- wherein
- the controller of the power storage pack that performs communication with the controller of the electric moving body or the controller of the charging device using the power line and the communication wiring, the controller of the power storage pack causing the first switch to be turned off and the second switch to be turned on, and
- the overvoltage protection circuit turns off the second switch upon detecting an overvoltage of the power line during communication between the controller of the power storage pack and the controller of the electric moving body or the controller of the charging device.
