Title: Charging of electric vehicles and construction machines
Inventor: THOMAS TWIGGER
IPC: H02J7/00
Filed: 2020-03-20
Abstract: Method and charge controller for managing the state of charge (SoC) of an electric work vehicle battery to be at a target SoC at a return to work time. A user selects a charge mode, which may correspond to a time-period, via an input 121, and data indicative of the mode is obtained. A target SoC and initial SoC 112, 111 are used to calculate a targeted charge increase 110. A charge cycle, comprising a charge rate, is selected based on charge mode and targeted charge increase. Charge start time tc is calculated 130 based on the charge rate and target charge increase. Initial and target battery temperatures 141, 142 are used to calculate a target temperature change and heat exchange start time tT 150. Battery temperature is adjusted at tT 160 so the battery is at the target temperature at charge start time 170. Charging commences at tc so the battery is at the target SoC at the return to work time 180. If the charge mode is a long-term storage-mode, the SoC may be adjusted to a storage SoC after the calculation of tT. The charge start time may additionally be based on electricity cost and environmental temperature.
