The parallel current limiting module is specially developed for pack parallel connection of the Lithium battery Protection Board. It can limit the large current between PACK due to internal resistance and voltage difference when PACK is parallel connected, effectively ensuring the safety of the cell and the protection plate.
Characteristics
v Easy installation
v Good insulation, stable current, high safety
v Ultra-high reliability testing
v The shell is exquisite and generous, has a full-enclosed design, is waterproof, dust-proof, moisture-proof, extrusion-proof, and other protective functions
Main technical instructions
External Dimension：63*41*14mm
Current limiting：1A、5A、15A
Open conditions: charging over current secondary protection or built-in open current
Release Condition: release
Operating temperature：-20~70℃
Function description
1. In the case of parallel connection, different pressure difference causes charge between battery packs,
2. Limit the rated charging current, effectively protecting the high current protection board and battery.
The connection between the internal protection board of each PACK and the parallel protector and the parallel connection between multiple packs are shown in the figure.
Wiring matters needing attention
1. The B-/p-plug of the parallel module should be connected first, then the B + Plug, and then the control signal wire should be connected,
2. Please strictly be in accordance with the wiring sequence operation, such as the wiring sequence reversed, which will lead to PACK parallel protection board damage.
CAUTION: BMS and shunt protector must be used together and not intermixed.
Warranty
For the company’s production of parallel PACK modules， we guarantee 3 years warranty on quality, if the damage is caused by human improper operation, we will conduct repair with a charge.
