No: 18/484031 Application Filed: October 10, 2023 Assignees: VOLVO TRUCK CORPORATION (Göteborg, SE) Claim: 1. A warning system for an energy storage system of a vehicle, the warning system comprising: an energy storage control unit configured to detect a hazardous condition of an energy storage; and an illumination system configured to illuminate a ground area adjacent to the vehicle at the location of the energy storage for which a hazardous condition is detected. Claim: 2. The warning system according to claim 1, wherein the energy storage control unit is configured to activate the illumination system when a hazardous condition is detected. Claim: 3. The warning system according to claim 1, wherein the energy storage control unit is configured to determine that a hazardous condition occur when an energy storage operating parameter from a predetermined group of operating parameters exceed a corresponding predetermined operating parameter threshold value. Claim: 4. The warning system according to claim 1, wherein the energy storage control unit is configured to detect an increase in temperature of the energy storage, and when the increase in temperature is faster than a predetermined temperature ramp threshold value, determine that the energy storage system is in a hazardous condition. Claim: 5. The warning system according to claim 1, wherein the energy storage control unit is configured to detect a temperature of the energy storage, and when the temperature is higher than a predetermined temperature threshold value, determine that the energy storage system is in a hazardous condition. Claim: 6. The warning system according to claim 1, wherein the energy storage control unit is configured to detect a cooling capacity of the energy storage, and when the cooling capacity is lower than a predetermined cooling capacity threshold value, determine that the energy storage system is in a hazardous condition. Claim: 7. The warning system according to claim 1, wherein the energy storage control unit is configured to detect a pressure within the energy storage, and when the pressure is higher than a predetermined pressure threshold value, determine that the energy storage system is in a hazardous condition. Claim: 8. The warning system according to claim 1, wherein the energy storage is a battery. Claim: 9. The warning system according to claim 1, wherein the illumination system comprises a plurality of light sources, wherein the light sources are arranged to form one of a plurality of predetermined patterns of a ground area adjacent to the vehicle at one or more locations on the ground adjacent to corresponding one or more locations of one or more energy storages of the vehicle. Claim: 10. The warning system according to claim 1, wherein the illumination system comprises a plurality of light sources arranged at a bottom edge of the energy storage. Claim: 11. The warning system according to claim 1, wherein the illumination system comprises one or more light sources arranged horizontally along a length of the energy storage. Claim: 12. A vehicle comprising a warning system according to claim 1. Claim: 13. Method of controlling a warning system for an energy storage system of a vehicle, the warning system comprising: an energy storage control unit and an illumination system configured to illuminate a ground area adjacent to the vehicle at the location of the energy storage, wherein the method comprises: detecting a hazardous condition of an energy storage; and controlling the illumination system to illuminate a ground area adjacent to the vehicle at a location of the energy storage. Claim: 14. The method according to claim 13, wherein detecting a hazardous condition comprises: monitoring a plurality of operating parameters of the energy storage; comparing the plurality of operating parameters with corresponding operating parameter threshold values; and when an operating parameter reaches a corresponding operating parameter threshold value, determining that the operating condition of the energy storage is a hazardous condition. Claim: 15. The method according to claim 13, wherein the operating parameter is at least one of temperature, temperature ramp, pressure and cooling capacity. Claim: 16. A computer program product comprising program code for performing, when executed by a processor device, the method of claim 13. Claim: 17. A control system comprising one or more control units configured to perform the method according to claim 13. Claim: 18. A non-transitory computer-readable storage medium comprising instructions, which when executed by a processor device, cause the processor device to perform the method of claim 13. Current International Class: 60; 60
