Abstract

Provided is a battery monitoring system including a plurality of batteries (213) connected in series, a current / voltage measuring unit (214p) configured to measure an electric current and a voltage of a first battery in response to a measurement instruction, and a plurality of voltage measuring units (214s) configured to measure a voltage of a second battery (213) other than the first battery (213) in response to a measurement instruction. The voltage measuring units (214s) are connected to the current / voltage measuring unit (214p) with a daisy-chain connection by a communication interface, and the current / voltage measuring unit (214p) and the voltage measuring unit (214s) transfer the measurement instruction to another voltage measuring unit (214s) through the daisy-chain connection.

Description

technical field [0001] Embodiments discussed herein relate to battery monitoring systems, battery packs, battery packs, and rideable machines. Background technique [0002] Using a lithium-ion battery pack (hereinafter, abbreviated as “LiB”) having high energy density as a battery pack for next-generation vehicles such as electric vehicles (EV) and hybrid electric vehicles (HEV) is mainstream. However, for reasons such as battery pack degradation control or ensuring safety (eg, preventing heat generation), it is difficult to charge LiBs as fast as the refueling time (eg, minutes) of gasoline-powered vehicles and the like. As a countermeasure, a technique of removing a battery module requiring charging and replacing it with a fully charged battery module has been proposed (for example, see US Patent No. 8,164,300). [0003] Meanwhile, it is an important functional requirement for an EV or HEV to accurately calculate the "electric mileage" of the EV or HEV corresponding to th...
