Abstract
In the battery control system pertaining to the present invention, one antenna is provided for each cell controller or each group of cell controllers. A battery controller switches between antennas by using a switch and performs wireless communication with each cell controller or each group of cell controllers. Hence, even if the number of cell controllers increases, a countermeasure can be taken by adding antennas and changing switches, and an increase in the number of battery controllers can be suppressed.
