Abstract: Methods and systems are provided for a hybrid transmission. In one example, a method for a hybrid transmission, comprising, adjusting voltage on an inverter of an electric motor prior to disconnecting or connecting a battery contact in response to a transition between a first mode and a second mode. In the first mode, a battery and at least the electric motor are used to power rotation of a transmission output shaft. In the second mode, an engine and at least the electric motor are used to power rotation of the transmission output shaft. In one example, the adjusting is initiated in response to a request to transition between the first mode and the second mode. In one example, the method includes controlling current to the battery to within a non-zero threshold of zero in response to the request to transition the first mode to the second mode.

Abstract: A dual battery charging and discharging system controls the configuration of multiple batteries arranged in multiple battery banks. The batteries within each bank are connected in series when powering an electrical load, such as a service motor, and are connected in parallel when charging. A microprocessor monitors the voltage levels of the batteries in each bank and controls relays to switch the electrical load over to a charged battery bank when the voltage level of the discharging battery bank drops below a minimum run threshold. The microprocessor also monitors the voltage levels of the charging battery bank and controls relays to cease charging when the voltage level rises above a minimum charge threshold. The batteries are charged by an alternator driven by a drive motor through a gear reduction system.
