Technical field

The present invention relates to a kind of intelligent equalizing charging method and device of electrokinetic cell of hybrid powered vehicle.

Background technology

On the orthodox car basis, hybrid vehicle has increased key components and parts such as high voltage power battery system, electric system, entire car controller.Wherein, the high voltage power battery system is made up of battery management system, high-voltage safety management system, heat management system and several series connected battery monomers, the Performance And Reliability of the performance impact car load of high voltage power battery system, and the performance of high voltage power battery system is relevant with battery cell performance, battery consistency, heat management system etc.

The high voltage power power brick is made up of several series connected battery monomers, because the otherness of battery manufacturing process, there is certain otherness in performance between the battery cell; Battery in use because the difference of surrounding environment will increase the inconsistency of battery cell, thereby reduces the operating efficiency of battery system, shortens the life-span of battery.

Be extending battery life, increase battery efficiency, hybrid power high voltage power battery need be done the equalization charge maintenance to battery after using a period of time.

Existing battery balancedization charge maintenance generally adopts energy transfer method or energy consumption method, it realizes that principle is the voltage that management system is monitored each battery cell, if voltage difference surpasses the scope that allows between battery cell, the management system control relay, control discharge resistance or electric capacity are connected with the battery cell that needs equalization, thereby realize energy consumption or transfer to battery cell, reach the purpose of battery cell equalization, but this battery cell equalization method cost height, need to consume certain energy, increased the difficulty of Machine Design and battery system heat management.

Summary of the invention

Goal of the invention of the present invention is to provide a kind of intelligent equalizing charging method and device of electrokinetic cell of hybrid powered vehicle, does not need to change battery system structure or increases the equalization charge maintenance that other extra device can be realized electrokinetic cell easily.

The present invention is based on same inventive concept and have three technical schemes:

1, a kind of intelligent equalizing charging method of electrokinetic cell of hybrid powered vehicle is characterized in that:

Have following steps:

A, power battery management system send the equalizing charge of battery request;

B, electrokinetic cell is charged, charge to electrokinetic cell SOC value and reach 100%;

C, with little electric current electrokinetic cell is continued charging, the charging interval is controlled in the safety time.

2, a kind of intelligent equalizing charging device of realizing the electrokinetic cell of hybrid powered vehicle of preceding method, it is characterized in that: have computer, program control charger, wherein computer connects the battery management system signal output part, the program control charger of pcs signal output termination, and program control charger connects battery body.

3, a kind of intelligent equalizing charging device of realizing the electrokinetic cell of hybrid powered vehicle of preceding method, it is characterized in that: have charge controller and charger, wherein the signal output part of charge controller connects charger, charge controller connects the battery management system signal output part, and charger connects battery body.

The beneficial effect that the present invention has:

The present invention realizes the equalization of electrokinetic cell is safeguarded by electrokinetic cell is overcharged, and does not need to change battery system structure or increases other extra device, makes the equalization charge maintenance of electrokinetic cell convenient.

Description of drawings

Fig. 1 is the structured flowchart of the embodiment of the invention 1;

Fig. 2 is the structured flowchart of the embodiment of the invention 2.

Embodiment

Embodiment 1: as shown in Figure 1, have computer, program control charger, wherein computer connects the battery management system signal output part, the program control charger of pcs signal output termination, and program control charger connects battery body.Battery management system is sent to computer with equalizing charge request, electrokinetic cell SOC value signal.

Battery management system has equalization charging forecast function, and battery management system is responsible for predicting whether battery needs to carry out the equalization charging, need carry out the equalization charging when predicting battery, and battery management system is to sending equalization charging request.

This scheme is applicable to the user of existing program control charging device, and only needing increases software control, can set up the intelligent equalization charging system, can reduce the cost of user's procuring equipment.

Embodiment 2: as shown in Figure 2, have charge controller and charger, charge controller and charger constitute independently charging system, and wherein the signal output part of charge controller connects charger, charge controller connects the battery management system signal output part, and charger connects battery body.Battery management system is sent to charge controller with equalizing charge request, electrokinetic cell SOC value signal.

Battery management system has equalization charging forecast function, and battery management system is responsible for predicting whether battery needs to carry out the equalization charging, need carry out the equalization charging when predicting battery, and battery management system is to sending equalization charging request.

Electrokinetic cell equalization charge step is as follows:

A, power battery management system send the equalizing charge of battery request to computer or charge controller;

B, program control charger or charger charge to electrokinetic cell, charge to electrokinetic cell SOC value and reach 100%;

C, with little electric current electrokinetic cell is continued charging, the charging interval is controlled in the safety time.

In step b, with big electric current electrokinetic cell is charged earlier, when electrokinetic cell SOC value reaches the high value, electrokinetic cell is carried out constant current charge with little electric current.Said electrokinetic cell SOC value reaches high value, is meant that SOC value of battery reaches 90%-95%; Said little electric current is meant that electric current is less than 1A-2A.

Like this, it is few that the battery cell that electric weight is many receives electric weight, and the electric weight that the battery cell that electric weight is few receives is many, and along with the increase of the time of overcharging, the electric weight otherness of battery cell reduces, thereby the equalization that realizes battery cell is safeguarded.
