Battery management system and method

A battery management method for a vehicle comprising a plurality of batteries, the method comprising:

• detecting an incoming hazard;
• predicting an impact of the incoming hazard with the vehicle using one or more sensors coupled to the vehicle;
• determining a course of action to be taken in response to the predicted impact;
• and
• controlling a subset of the plurality of batteries according to the determined course of action;
• wherein the one or more sensors comprise one or more radar units and predicting an impact comprises receiving radar data concerning information about the incoming hazard;
• wherein the radar data comprises information concerning direction of arrival;
• wherein predicting the impact comprises, based on the direction of arrival information, predicting a location of the impact of the incoming hazard on the vehicle;
• wherein the radar data further comprises range, velocity and radar cross section information;
• and
• wherein predicting the impact comprises, based on the range, velocity and radar cross section information, a predicted force of the impact and/or a predicted time of the impact.
