Vehicle
An electrically driven vehicle includes a battery pack including a battery ECU, a gate ECU provided separately from the battery pack, and an HVECU provided separately from the battery pack and the gate ECU and configured to control any one of battery power and battery current of the battery as a control target. The gate ECU is installed at a position outside the battery pack and relays communication between the battery ECU and the HVECU.
1. A vehicle comprising:
a battery pack including a secondary battery, a first battery sensor configured to detect a state of the secondary battery, a first electronic control device, and a system main relay;
a second electronic control device including a storage device that stores prescribed information acquired from the battery pack; and
a third electronic control device provided separately from the battery pack and the second electronic control device, and programmed to control any one of battery power and battery current of the secondary battery as a control target, wherein
the second electronic control device is installed at a position outside the battery pack,
the second electronic control device is programmed to relay communication between the first electronic control device and the third electronic control device, and
the first electronic control device controls the system main relay according to an instruction from the third electronic control device.
2. The vehicle according to claim 1 , wherein the second electronic control device is installed at a position above the battery pack in the vehicle such that the second electronic control device is not influenced by heat generated in the battery pack.
3. The vehicle according to claim 1 , wherein
the battery pack is installed outside a cabin of the vehicle, and
the second electronic control device is installed inside the cabin of the vehicle.
4. The vehicle according to claim 1 , wherein the second electronic control device is installed in a state of being covered with a thermal insulation material.
5. The vehicle according to claim 1 , wherein the second electronic control device is programmed to store, in the storage device, history information on information exchanged between the first electronic control device and the third electronic control device.
6. The vehicle according to claim 5 , wherein the second electronic control device is programmed to store, in the storage device, the history information in a latest predetermined period.
7. The vehicle according to claim 1 , wherein
the first electronic control device is programmed to calculate a first limit value for the other one of the battery power and the battery current, using a detection value of the first battery sensor,
the second electronic control device is c programmed to convert the first limit value calculated by the first electronic control device into a second limit value corresponding to the control target, and
the third electronic control device is programmed to control the control target, using the second limit value.
