[0079] Figure 6 A first example in which the present disclosure has been applied to a configuration of an electric storage system having n electric storage modules MOD1 to MODn is shown. The power storage modules include communication units COM1 to COMn, isolators ISC1 to ISCn, module controllers CNT1 to CNTn, and battery block groups BB1 to BBn, respectively. The n power storage modules are connected to the control box ICNT. For this connection, the communication lines L1 and L2 and the power line Lp are used. Bidirectional communication between the control box ICNT and the power storage modules MOD1 to MODn is performed via communication lines L1 and L2. For example, CAN is used as the communication protocol. Recently, CAN is used for in-vehicle LAN.

[0080] Each communication unit COM1 to COMn in the storage module corresponds to Figure 5 The communication unit 17. Therefore, with Figure 5 Compared with the structure of Figure 6 The module controllers CNT1 to C...

[0160] In the first example of the power storage system discussed above, the isolators ISC1 to ISCn are placed between the communication units COM1 to COMn and the module controllers CNT1 to CNTn, as Figure 6 shown. However, the second example of the power storage system is configured such that the isolators ISC1 to ISCn are interposed between the communication units COM1 to COMn and the control box ICNT, as Figure 29 shown. The isolators ISC1 to ISCn and the control box ICNT are connected by communication lines L1 and L2 and a power line Lp. Use an interface such as SPI or CAN as the communication interface. although Figure 29 The intermediate isolators ISC1 to ISCn are placed inside the power storage modules MOD1 to MODn, but they may also be placed outside the modules.

[0161] Similar to the first example discussed above, the isolators ISC1 to ISCn are used to isolate the communication units COM1 to COMn and the control box ICNT from each other, supply power supply ...

Abstract

A power storage apparatus, electric device, electric vehicle, and power system are disclosed. In an example embodiment, a power storage apparatus includes a battery block comprising a plurality of battery cells and an isolating unit that enables wireless information transfer regarding battery information of the battery block.

Description

technical field [0001] The present disclosure relates to an electric storage device and an electric vehicle utilizing electric power from the electric storage device. Background technique [0002] Recently, secondary batteries such as lithium ion batteries have been rapidly spreading to applications such as storage batteries for automobiles and power storage devices in which the secondary batteries are combined with alternative energy systems such as solar cells or wind turbines. In the case of using a large number of power storage elements such as unit cells (also referred to as power cells or single cells, and appropriately referred to as battery cells in the following description), in order to generate a large output, a plurality of power storage modules are connected in series Structure. The power storage module includes a battery block in which a plurality of battery cells (for example, four) are connected in parallel and / or in series. A large number of battery blocks...
