Abstract: A vehicle communication system includes: a control device 10B provided in a vehicle; and a management device 50 that is provided in a battery 20 mounted on the vehicle while communicably connected to the control device 10B. One of the control device 10B and the management device 50 discriminates a communication specification of the other and switches the communication specification. In this configuration, consistency of the communication specification is attained between the control device 10B of the vehicle and the battery 20, so that disability of communication between the control device 10B and the battery 20 can be prevented.

Abstract: An energy storage apparatus includes: an energy storage device which is connected to a vehicle load and a vehicle power generator; a current interrupt device that causes the energy storage device and the vehicle load as well as the energy storage device and the vehicle power generator to be in a conduction state or in an interruption state; a voltage detection unit that detects voltage of the energy storage device; and a control unit. The control unit executes: a switching instruction process in which, when determining that the electric storage device will reach an overcharge state on the basis of the voltage, the control unit issues an interruption switching instruction to the current interrupt device; and an interruption maintaining process in which, when the number of times of the switching instruction process exceeds a predetermined value, the control unit issues an instruction to maintain the interruption state.

Abstract: An energy storage device management method for deciding an SOC estimated value includes: preparing first and second SOC estimation methods for estimating an SOC; and employing a predetermined value as the SOC estimated value when a first SOC region and a second SOC region are different. V-SOC correlation between a voltage and the state of charge of the energy storage device is sectioned into a plurality of SOC regions. The first SOC region is the SOC region that the SOC estimated by the first SOC estimation method belongs to, and the second SOC region is the SOC region that the SOC estimated by the second SOC estimation method belongs to. The predetermined value is set to a value close to a boundary value on a side close to the first SOC region of boundary values sectioning the second SOC region, or a value between the boundary value and an intermediate value of the second SOC region.
