Detection control circuit

Abstract

The invention discloses a detection control circuit, comprising a detecting unit, an amplifying unit and a driving unit, wherein the detecting unit comprises a semiconductor tube with PN (positive negative) junctions which are connected in a circuit loop in series and complete forward conduction in the charging or discharging process of the circuit loop so as to generate tube voltage drop at the two ends of the PN junctions; the amplifying unit is connected with the detecting unit and amplifies the tube voltage drop so as to generate a control voltage; and the driving unit is connected with the amplifying unit and responses the control voltage to output a driving signal. The detection control circuit has the characteristics that the power consumption of the detection control circuit can be effectively reduced by the mode.

Description

【Technical field】 [0001] The invention relates to a detection control circuit, in particular to a detection control circuit that can be used in a management system of energy storage products such as batteries. 【Background technique】 [0002] The practical application of energy storage products, especially lithium batteries, needs to be monitored, controlled and protected by electronic circuits. Because such monitoring, control and protection circuits need to be connected to batteries for a long time, the working current of the circuit comes from the battery. The function of monitoring, control and protection circuits Power consumption directly affects battery life and efficiency after a single charge. [0003] During the use of the battery, it is in a static state for most of the time, that is, there is no charge and discharge current, so the working state of the monitoring control protection circuit is generally divided into the sleep state when standing still and the worki...

Problems solved by technology

However, this method will frequently wake up the processor from sleep mode, and the wake-up cycle is generally not too long. If it is too long, the action response time of the protection board will be too slow, and the battery cannot be processed immediately when an alarm such as over-discharge or over-charge occurs.

Because there will be a large inrush current every time it wakes up, the average current in the frequent wake-up process is still large, and it will also affect the circuit stability due to frequent current shocks
