How to solve the problem of 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.

What are battery limit calculations?

The limit calculations take into account the health of the battery pack, internal resistance, battery temperature, and also enforce the maximum pre-set limits in the programmable battery profile for current draw at various temperatures. Values can be expressed in amps or kilowatts for automotive applications.

What happens if you don't have a reliable battery limit?

Failure to have reliable limits can allow the main control computer to draw too much current from the battery, causing the limits to suddenly dive. In order to respect the new limit, the main drive computer would be forced to reduce current, leading to a jerky or possibly dangerous driving experience.

What is the input current limit?

The input current limit is active during normal operation as well as during startup. This effectively limits the inrush current, and can also be used to reliably charge heavy loads, such as a supercapacitor, from a weak battery. The converter has eight current limit settings going down to 1 mA, as listed in Table 1.
