Method for operating e.g. cooling agent compressor of hybrid vehicle at hundred volt-battery, involves controlling load and inverter such that operating voltage value is not lowered, during discharging of battery

摘要

The method involves charging or discharging of a battery (1) via electrical conductors (2) e.g. loads, by a load (3) and inverter. Voltage (Vb) at the battery, voltage (Vk) at the load and inverter are measured. The battery voltage is transmitted to the load and inverter in a periodical interval. The load and the inverter are controlled such that operating voltage value does not exceed, during charging of the battery and/or the operating voltage value is not lowered, during discharging of the battery based on difference voltage between the battery voltage and voltage at the load and inverter. An independent claim is also included for a device for operating the load and inverter at the battery.
