Provided are a battery management system (BMS) and a battery system capable of accurately measuring a voltage without using a precise resistance element and reducing an error even when operating in a wide temperature range. Since a correction amount for the resistor included in the voltage measurement module is generated using a diagnostic power source configured independently of the battery system, and a voltage of the circuit included in the battery system is measured by applying the generated correction amount, the voltage may be precisely measured without using a high-precision resistance element. Since a changeover switch operates periodically to generate and apply an updated correction amount according to a changing environment, the voltage may be precisely measured even if it is applied to a system in which the environment continuously changes, such as a driving electric vehicle.
