Customer ServiceThe precharge relay needs to be rated for the full battery voltage, because, when the system is off, the full battery voltage appears across its contacts.
The relay needs to be able to handle the peak of the inrush current; but, since the average current is low, and the breaking current is nearly zero, the current rating of the relay is not critical. The resistance of the precharge resistor is chosen based on the capacity of the load and the desired precharge time.
When the battery pack contactors are closed onto a motor and inverter there will be an inrush of current into the inverter capacitor. This very high current is at a minimum likely to age the contactors, it could permanently damage the contactors. Therefore, when we closed the contactors on the battery pack we do this in three steps:
There are a number of reasons for contactor failure: There are a number of companies that make contactors, some are electro-mechanical, solid state and a mix of both technologies. When the battery pack contactors are closed onto a motor and inverter there will be an inrush of current into the inverter capacitor.
In a battery the contactors are a switch that can be operated by the control system. They are essentially a relay. These contactors are designed to be able to break (switch off) the circuit under full load (maximum current and at maximum system voltage). There are two main types of contactors: Normally Open (NO) and Normally Closed (NC).
