Abstract

The utility model relates to an internal resistance measurement apparatus of a square battery. The internal resistance measurement apparatus comprises a pedestal and a standing plate vertically arranged at the pedestal. The pedestal is segmented into a front zone and a rear zone for placing a to-be-measured battery by the standing plate; two symmetrical chutes are arranged at the front surface and the back surface of the standing plate; and measuring contacts for measuring resistance of the measured battery are installed in the chutes in a sliding way. Besides, a plurality of fixing rings for fixing a positive measuring pen and a negative measuring pen are respectively arranged at the left side and the right side of the standing plate; corresponding measuring pen contacts are arranged right below the fixing rings at the two sides; and the two measuring pen contacts are respectively connected with the corresponding measuring contacts by electric wires. And the positive measuring pen and the negative measuring pen and the measured battery form a measuring circuit respectively by the corresponding measuring pen contacts and the corresponding measuring contacts. According to the scheme, dual-station detection is carried out; and the area and force of measuring contact contacting with the batter each time are consistent, thereby effectively reducing the measuring error.

Description

A kind of rectangular cell is surveyed internal resistance device

Technical field

The utility model relates to a kind of internal resistance device of surveying, and relates to specifically a kind of rectangular cell and surveys internal resistance device.

Background technology

Along with scientific and technological development, the kind of battery is more and more, and the capacity of battery is also increasing, jumbo battery general Practical square structure all now, battery must carry out to it measurement of internal resistance in producing, and whether produces the problems such as internal short-circuit to test it.Common metering system takes reometer manually to touch electrode measurement, and owing to manually having instability, measuring position and touching strength are uneven, therefore often there is measuring error.

Utility model content

The utility model, in order to solve above-mentioned technical matters, provides a kind of rectangular cell to survey internal resistance device, and it detects stable, can ensure to measure the consistance of rectangular cell internal resistance.

The technical scheme that the utility model adopts is: a kind of rectangular cell is surveyed internal resistance device, comprise base and be vertically set on the riser on base, described riser is divided into former and later two for placing the region of tested battery by base, on former and later two surfaces of described riser, be provided with two symmetrical chutes, in chute, be slidably installed and be useful on the measurement contact of measuring tested cell resistance, the described riser left and right sides is also respectively arranged with the set collar of multiple fixing anodal measuring pen and negative pole measuring pen, under the set collar of both sides, be equipped with corresponding measuring pen contact, two measuring pen contacts are connected with the corresponding contact of measuring by electric wire respectively, anodal detecting pen and negative pole detecting pen are respectively by corresponding measuring pen contact, measure contact and tested battery and form metering circuit.

The beneficial effects of the utility model: the utility model carries out double detection, the area of the each contact measurement contact of battery is consistent with strength, has effectively reduced the error of measuring.
