摘要： A method for managing state of charge of a battery of an electric work vehicle to be ready to return to work at a return to work time. Data comprising an expected date and time of return to work is obtained from the output of a user interface and used to calculate an expected duration of immobilization of the electric work vehicle. A charge rate is determined based on the expected duration of immobilization of the work vehicle and a targeted charge increase. A charging start time is calculated such that at the return to work time an actual state of charge of the battery is a target operational state of charge value. The temperature of the battery is adjusted such that the battery is at a target temperature at the charging start time. The charge cycle is started at the charging start time.

摘要： A method of using a radio frequency sensor for determining an estimate of soot load in a diesel particulate filter is disclosed, The method comprises: receiving a first mean attenuation value derived from attenuation values for each of a first plurality of radio frequencies within a first band of radio frequencies detected by the radio frequency sensor; and receiving first standard deviation data for the mean attenuation value relating to the first plurality of radio frequencies within the first band of radio frequencies. The method further comprises: determining whether the standard deviation data exceeds a standard deviation threshold, In the event that the standard deviation data does not exceed a standard deviation threshold, the method uses the first mean attenuation value to infer a value for soot load in the diesel particulate filter, in the event that the standard deviation data exceeds a standard deviation threshold, the method comprises: receiving a second mean attenuation value derived from attenuation values for each of a second plurality of radio frequencies within a. second band of radio frequencies; and receiving second standard deviation data relating to the mean attenuation value for a second plurality of radio frequencies within the second band of radio frequencies detected by the radio frequency sensor, In the event that the second standard deviation data does not exceed the standard deviation threshold, the method uses the second mean attenuation value to infer the value for soot load in the diesel particulate filter.
