Development of bespoke hardware and software to enable testing of a novel method of managing the charge and discharge of series-connected battery packs

The novel feature of the method of battery management under development and testing is that routine balancing of the cells is eliminated throughout the service life of the battery pack. This requires preparation of the battery cells and configuration of the rigs in such a way as to ensure that the cells are accurately balanced on assembly and that thereafter there is no cell-to-cell variation in charge current or load at any time, measured to a low microamp level. In addition, the method requires a special charge control algorithm which was devised in order to accommodate cell-to-cell variations in capacity and dynamic response.Comprehensive experimental testing of this method, which is fully described in the associated paper (Hardy et al., 2023), required the development of hardware and software which would combine the necessary functions of a battery test rig and a battery management system capable of carrying out the special method of charge control described below. These included: • The automated control of contactors, loads and chargers to perform multiple charge/discharge cycles to predetermined patterns of current and maximum and minimum cell voltages. • Monitoring of cell voltages, current and temperature and the provision of test and diagnostic data. • Performing the safety functions of a Battery Management System to ensure that no cell was permitted to exceed limitations of current, voltage or temperature.The hardware and software were developed through three phases of testing with the operational principles (but not all the hardware and software elements) carrying over from one phase to the next

Proactive biological control: A cost-effective management option for invasive pests

Proactive biocontrol could accelerate responses to invasive pests in urban areas — where pesticide use may be unpopular — before they spread to agricultural areas

Classical Biological Control of Invasive Legacy Crop Pests: New Technologies Offer Opportunities to Revisit Old Pest Problems in Perennial Tree Crops

Advances in scientific disciplines that support classical biological control have provided “new tools” that could have important applications for biocontrol programs for some long-established invasive arthropod pests. We suggest that these previously unavailable tools should be used in biological control programs targeting “legacy pests”, even if they have been targets of previously unsuccessful biocontrol projects. Examples of “new tools” include molecular analyses to verify species identities and likely geographic area of origin, climate matching and ecological niche modeling, preservation of natural enemy genetic diversity in quarantine, the use of theory from invasion biology to maximize establishment likelihoods for natural enemies, and improved understanding of the interactions between natural enemy and target pest microbiomes. This review suggests that opportunities exist for revisiting old pest problems and funding research programs using “new tools” for developing biological control programs for “legacy pests” could provide permanent suppression of some seemingly intractable pest problems. As a case study, we use citricola scale, Coccus pseudomagnoliarum, an invasive legacy pest of California citrus, to demonstrate the potential of new tools to support a new classical biological control program targeting this insect

Financial effect of limiting pesticide use near schools for almonds in nine counties depends on soils and weather

Effective Jan. 1, 2018, the California Department of Pesticide Regulation enacted a regulation regarding the use of pesticides near public K-12 schools and licensed child day care centers, including a provision that bans specific types of applications, including air-blast and air-assist, during weekday school hours (6 a.m. to 6 p.m.) to provide an additional safety margin for pesticide exposure beyond those provided by other regulations. We considered the financial effect on almond growers in nine counties, accounting for four-fifths of total almond production in 2014, if they had been unable to complete a standard spring disease management program on any buffer zone acreage. Results indicated that total annual losses for those counties if such a regulation had been in effect would have been $8.7 million, with per-acre losses ranging from 22$0.2 million because the regulation would have affected the number of sprays completed for relatively few acres in relatively few years
