On-board computer for electric vehicle, has microprocessor to acquire values e.g. charging and traction current and battery voltage, and LCD-dot-matrix display to display acquired values and certain values e.g. charged ampere-hour

摘要

The computer has a microprocessor with integrated AD converter and a multiplexer to acquire and process electrical values such as charging current, traction current and battery voltage. An LCD-dot-matrix display (1) displays the acquired electrical values and certain values e.g. charged ampere-hour and discharged ampere-hour, attained by further processing using the microprocessor.
