Reasons for battery cabinet current exceeding limit

What is battery charging current limit?

The Battery Charging Current Limit block calculates the maximum charging current of a battery. Limiting the charging and discharging currents is an important consideration when you model battery packs. This block supports single-precision and double-precision floating-point simulation.

Why does a battery need a maximum charge current?

Max charge current allows the high performance of a battery. It prevents the chemical and physical stresses commonly due to exceeding the current limit during charging. Thus, the battery maintains the charging speed and enhances its efficiency. A specific voltage limit is required to charge the battery, affecting the battery’s health efficiently.

What happens if you charge a battery over the maximum charge current?

Charging the battery above the max charge current limit can destroy its internal components. As a result, the battery can lose its functioning. However, the battery with a maximum charging current prevents the wear and tear of its components and preserves its lifespan. Max charge current allows the high performance of a battery.

Why should battery current be artificially limited?

With some batteries the current should be artificially limited to protect the battery from self-destruction. It may be able to produce a high current for a short time and then chemical products build up that limit the current ("polarization"). The electrolyte and connections will have some resistance and that limits the current.
