Abstract
A technique controls charge on a lithium battery of a utility vehicle. The technique involves operating electronic circuitry of the utility vehicle in a normal operating mode in which the electronic circuitry charges the lithium battery to a normal charge level. The technique further involves, after operating the electronic circuity in the normal operating mode, transitioning the electronic circuitry from the normal operating mode to a storage mode in which the electronic circuitry is configured to set an amount of charge on the lithium battery to within a predefined storage range (or level) which is lower than the normal charge level. The technique further involves, in response to transitioning the electronic circuitry, adjusting the amount of charge on the lithium battery from an initial charge level which is outside the predefined storage range to an adjusted charge level which is within the predefined storage range.
