The invention belongs to the technical field of new energy automobile power supply safety, and particularly relates to a battery management system and a vehicle controller, the battery management system comprises a high-voltage loop used for cooperating with a battery to supply energy through external discharge or charge energy storage, and the high-voltage loop is provided with a plurality of different relays, different relays cooperate with each other so that the high-voltage loop can be switched between different working conditions. The high-voltage sampling module is used for acquiring voltage signals at different sampling points on a high-voltage loop; the control module is in communication connection with the high-voltage sampling module and is used for carrying out fault diagnosis on different relays according to voltage signals fed back by the high-voltage sampling module; and the control module is also used for monitoring the working state of the high-voltage sampling module so as to carry out reset operation on the high-voltage sampling module when the high-voltage sampling module breaks down. According to the invention, the abnormal fault of the high-voltage sampling chip can be identified and reset in time, the reliability of the high-voltage sampling chip is improved, and the safety and stability of a battery high-voltage loop are ensured.
