A battery pack includes a rechargeable battery module and a battery management system for controlling charging and/or discharging of the battery module. The battery module may include a substantially linear charging and discharging voltage-time profile within at least part of the charging and discharging cycle of the battery module, and the battery management system may be configured to calculate a state of charge of the battery module by using linear charging and/or discharging characteristics of the battery module.
