An object of the invention is to improve communication quality in a power storage management system.

The above-mentioned problem may be solved by the following one solution. When a communication error where transmission, reception, or both transmission and reception of a signal is not allowed occurs between one or a plurality of a plurality of information acquisition devices that acquires states of a plurality of power storage cells and an information collection device that communicates with the plurality of information acquisition devices in a time-division manner, and collects information related to the states of the plurality of power storage cells acquired by the plurality of respective information acquisition devices, a process for resolving a communication error is executed by putting all the plurality of information acquisition devices in a state in which communication with the information collection device is allowed at all times. Here, the plurality of information acquisition devices is in a state in which communication with the information collection device is allowed in a first period in which the plurality of information acquisition devices communicates with the information collection device, and is in a state in which the state, in which communication with the information collection device is allowed, is canceled in a second period in which other information acquisition devices communicate with the information collection device in a relation of n to 1 (n is a positive natural number indicating the number of communication channels of the information collection device).

The disclosure relates to a method for controlling an electrical system of an electrically drivable motor vehicle, wherein the electrical system includes at least one lead battery and at least one lithium battery. Initially, a lower and a first upper threshold value for a state of charge of the lithium battery are determined. Then, a second upper threshold value which is higher than the first upper threshold value is determined. During the driving operation of the motor vehicle, a state of charge of the lithium battery is set between a lower and a second upper threshold value. When the motor vehicle is switched off, the state of charge of the lithium battery is determined. If the state of charge of the lithium battery is higher than the first upper threshold value, the state of charge of the lithium battery is lowered to the first upper threshold value.
