Test items

1. Performance test of battery charge and discharge.
2. Cycle life testing of batteries.
3. Self-discharge capacity test of batteries.

System characteristics
1. Positioning mode of the tray: Twice positioning mode is adopted for the tray positioning. First positioning is made to use the guide block around the mechanical unit and the second is the precise positioning of the dowel pins on the diagonal line.
2. Action method: The probe driving mechanism drives the probe module to crimp the cell lug, and the screw rod can be adjusted to change the lug depth crimped by the probe. After detection and crimping are completed, the system will distribute process steps to charge or discharge the batteries automatically.

Functional characteristics

1. Two rows of fans for blowing and cooling are designed under each storage location, with the air blowing evenly from bottom to top, and the thermal homogeneity of storage location is controlled to be no greater than ±2℃. 2 smoke detectors are designed to be installed on the air flue according to the air flue route for each storage location, to monitor and protect the storage position in a real-time way;
2. Probe clamping mechanism: the probe is pressing-type, composed of insulation material and the lug contact pieces, where three contact pieces are current needles, one is for voltage sampling; pressing-type probe pinhead is serrated, gold-plated beryllium copper, with small contact resistance and high current temperature rise less than 10℃, to ensure precision of current passing through and accuracy of voltage sampling; probe module entirely adopts modular design, indicating short time of installation, adjustment and replacement, easy to maintain.
3. Clamping device is compatible with unilateral edge lug and bilateral edge lug, which can realize rapid change of type; meeting customers' personalized requirements.

4. Detecting and judging voltage line or current line bad contact during battery core charging/discharging process, based on original voltage sampling collection battery voltage V1, a voltage V2 on voltage sampling collection power output line is added, which can monitor in the whole process whether the crimping of current and voltage probes is in good condition, in order to completely solve the problem of overcharged or overdischarged phenomenon caused by bad contact of clamping device.
