摘要： A vehicle having an ambient temperature sensor, a low voltage lithium-ion battery and a controller is provided. The controller is configured to monitor the ambient temperature sensor and based on a determination that an ambient temperature is below a threshold value, provide an alternating current power to the low voltage lithium-ion battery. The alternating current power causes the low voltage lithium-ion battery to heat.

摘要： The invention relates to the technical field of battery charging and swap, and in particular to an off-line battery swap method, a battery charging and swap station, a vehicle with a battery to be swapped, and a readable storage medium. The invention is intended to solve the problem that battery swap cannot be performed at a battery charging and swap station when a vehicle is not connected to a network or a cloud server has a fault. To this end, the off-line battery swap method of the invention includes: switching, by a battery charging and swap station, to a backup battery swap mode upon receiving a battery swap mode switching instruction; establishing, by a vehicle with a battery to be swapped, a communication connection with the battery charging and swap station by using backup connection information; authenticating, by the battery charging and swap station, the vehicle with a battery to be swapped; and performing, by the battery charging and swap station, battery swap for the vehicle with a battery to be swapped where the authentication is successful, the backup connection information being pre-stored in the vehicle with a battery to be swapped. According to the battery swap method of this application, a battery swap procedure can be completed in an off-line state, thereby effectively solving the problem that battery swap cannot be performed when a cloud server has a fault or a vehicle with a battery to be swapped is not connected to a network.

摘要： The disclosure describes a method for detecting an arc in a direct-current (DC) circuit comprising a DC load, a DC source supplying the DC load, and a circuit arrangement arranged between the DC source and the DC load. A power flow P between an input and an output of the circuit arrangement is suppressed by means of a switching circuit through cyclical interruption such that the power flow P is enabled in an active time window with the first period Δt1 and the power flow P is suppressed in an inactive time window with the second period Δt2. Via detection of an input current Iin flowing at the input and/or an input voltage Uin applied to the input and comparison of values of the input current Iin and/or input voltage Uin detected in the inactive time window with a current threshold value ITH or a voltage threshold value UTH an arc presence criterion is signaled if the input current Iin detected in the inactive time window falls below the current threshold value ITH and/or the input voltage Uin detected in the inactive time window does not exceed the voltage threshold value UTH. The application also describes a circuit arrangement for detecting an arc and a photovoltaic (PV) inverter including such a circuit arrangement.
