Battery is as the energy of the frequent electronic product that uses in people's routine work, the life, and the security performance of its use more and more is subject to concern and the attention of the producer, user and testing agency.Primary element is mainly sold in the commercial market, its security is particularly important, International Electrotechnical Commission think the security of battery be battery product to the repellence of unacceptable risk, be the potential source that damages, might cause physical damnification or destruction to health of human body, environment is damaged.At home, the GB8897.5-2006 " primary element the 5th partially aqueous solution electrolyte safety requirements " of new revision also the security performance of primary element as the compulsory test project.
Reasonably can predict misuse is the important security performance project of primary element, it refers to that the user does not use according to the condition of supplier's appointment, safeguard and treatment of battery, cause the battery faulty operation, comprise: external short circuit, the part battery is by upside-down mounting, the reverse voltage of external power, the battery and the new battery series winding of not letting slip electricity of electricity have been let slip, the unusual high battery of internal resistance is connected with the normal battery of other internal resistances, consequent generation short circuit, mistake charging, the reversal connection charging, the situations such as overdischarge, may cause electrolytical loss, leak, break, might cause battery on fire when serious, blast.
By simulating various maloperation situations, battery is detected, thereby it is made the security performance objective evaluation, to reduce or to avoid the generation of this damage or destruction.
Primary element reasonably can be predicted and misapply at home and abroad that there is requirement in institute in the standard, yet above-mentioned checkout equipment there is no standardization, regularization.Therefore study detection method and checkout equipment, simulate various foreseeable misuse situation, primary element is carried out security performance detect, its meaning is extremely huge.
Summary of the invention
The purpose of this utility model is exactly to be for the deficiencies in the prior art, the solution of battery safety measuring technology is provided, by designing a kind of battery safety simple detection device, this instrument can be simulated common various foreseeable battery misuse situation, comprise external short circuit, the part battery is by upside-down mounting, the reverse voltage of external power, the battery and the new battery series winding of not letting slip electricity of electricity have been let slip, the unusual high battery of internal resistance is connected with the normal battery of other internal resistances etc., realize that by detecting battery is installed incorrectly situation classifies, the security performance of battery is made objective evaluation, guarantee the safe handling of battery product;
The utility model is to realize by such technical scheme: a kind of primary element misoperation safety device for detecting performance, it is characterized in that, consisted of by battery safety detection control box and battery clamp, described battery safety detects in the control box and comprises voltage table, reometer, ohmmeter, variable resistor and resistance adjustment device;
Described battery clamp is in series by some single battery anchor clamps, between the positive/negative plate of single battery
Distance can be regulated from 0~20cm;
Voltage table is attempted by between the battery clamp both positive and negative polarity; Reometer, variable resistor and battery clamp are concatenated into back
The road; The resistance adjustment device is used for regulating variable resistor; Voltage table, reometer, ohmmeter and battery folder in the loop
Connecting line between the tool adopts conductance to make less than 0.02 ohm copper cash.
The beneficial effects of the utility model are: tested battery and boosting battery are placed on the anchor clamps, according to test request to connecting, simulate common various foreseeable battery misuse situation, such as external short circuit, the part battery is by upside-down mounting, the reverse voltage of external power, the battery and the new battery series winding of not letting slip electricity of electricity have been let slip, the unusual high battery of internal resistance is connected with the normal battery of other internal resistances etc., realization is installed security performance incorrectly to battery and is detected, and the utlity model has simple in structure, easy to operate, safe and reliable characteristics, its cost is low, effective, have practicality and promotional value.
