Battery fastening system and method

A battery fastening system for fastening a battery in a vehicle, the battery fastening system comprises:

• a battery tray having a length direction and a width direction, wherein the battery tray is configured to be fastened to the vehicle;
• a first corner fastening device located at a first corner of the battery, the first corner fastening device configured to limit movement of the battery towards a first side of the battery tray in the length direction and towards a first side of the battery tray in the width direction, and further configured to secure the battery to the battery tray,
• a second corner fastening device separate from the battery tray and located at a second corner of the battery different than the first corner of the battery, the second corner fastening device configured to limit for limiting movement of the battery towards the first side of the battery tray in the length direction and towards a second side of the battery tray in the width direction, and further configured to secure the battery to the battery tray, wherein the second corner fastening device is securable to the battery tray in at least two different positions in the width direction for fastening of batteries with at least two different sizes in the width direction,
• a clamping element configured to limit movement of the battery towards a second side of the battery tray in the length direction, and further configured to secure the battery to the battery tray, wherein the clamping element is securable to the battery tray in at least two different positions in the length direction for fastening of batteries with at least two different sizes in the length direction of the battery tray,
• wherein the first corner fastening device has a first battery engaging surface normal to the length direction that engages a side of the battery normal to the length direction and a second battery engaging surface normal to the width direction that engages a first side of the battery normal to the width direction, and the second corner fastening device has a first battery engaging surface normal to the length direction that engages the side of the battery normal to the length direction and a second battery engaging surface normal to the width direction that engages a second side of the battery normal to the width direction;
• wherein the first and second corner fastening devices are further configured to engage a foot of the battery to press the battery against an upper surface of the battery tray, the foot protruding laterally from at least one side of the battery adjacent a bottom of the battery.
