Problems solved by technology

[0003] At present, there are two mainstream LED display control schemes: one is to control the LED display by using the battery voltage, battery current, and battery internal resistance information to perform precise calculations to generate its power curve, but this scheme is more complicated and consumes a lot of resources; The other is to display only roughly based on the battery voltage. Although this solution consumes less resources, in actual application, the detected battery voltage will be different in different states and different currents, causing many display problems.

Abstract

Disclosed are an apparatus and a method for LED display control in a charge and discharge system. The apparatus includes a display code generator configured to generate a charging display code or a discharging display code based on a voltage signal and a charging state signal of a battery in a charging and discharging system, an LED display enable signal, and a plurality of preset voltage threshold signals; and a decoding driver configured to decode the charging display code or the discharging display code according to the charging state signal to generate a driving signal for driving the LEDto display.

Description

technical field [0001] The present disclosure generally relates to the technical field of charge and discharge, and more particularly relates to a device and method for display control of a light emitting diode (LED) in a charge and discharge system. Background technique [0002] In most charging and discharging systems, LED lights are often used to visually display the working status of the charging and discharging system and battery power. [0003] At present, there are two mainstream LED display control schemes: one is to control the LED display by using the battery voltage, battery current, and battery internal resistance information to perform precise calculations to generate its power curve, but this scheme is more complicated and consumes a lot of resources; The other is to display only roughly based on the battery voltage. Although this solution consumes less resources, in actual application, the detected battery voltage will be different in different states and diff...
