  Connectors are necessary components for series and parallel connections between lithium battery packs. Choosing appropriate connectors is the focus of the lithium battery pack process.

  One of the key points in choosing what kind of connector is to consider the temperature rise of the lithium battery in the working state and the limit state.

  So how to choose the right connector?

  1. Choose suitable connectors with low temperature rise characteristics

  When the lithium battery is charged and discharged, the passage of a large current will cause the connector to produce a thermal effect. When the temperature of the connector rises and exceeds the temperature of the battery, the high temperature will be transmitted to the inside of the battery, which will affect the stability of the battery, so the connector The temperature rise characteristic is an important parameter.

  2. Keep the contact area of the connector large enough

  When using the connector, ensure that the metal parts are kept in the best contact area, which can effectively reduce the contact resistance and reduce the heating power.

  3. Choose a material with good conductivity

  The metal material of the connector is preferably pure copper, silver-plated, gold-plated, etc. In this way, the effect of high conductivity and stable temperature rise of overcurrent can be achieved.

  The connector is an indispensable part of the lithium battery, and the temperature rise effect has a great impact on the entire lithium battery system, and the appropriate connector must be carefully selected.

  Lithium-ion battery (LIB) has become the main energy storage solution in modern social life. Among them, lithium iron phosphate batteries are a perfect replacement for lead-acid batteries, and they are the first choice for grid-connected peak shaving, off-grid energy storage, photovoltaic energy storage, UPS, data center and other industries.
