A battery switching method and apparatus, and a method and apparatus for sending a battery switching signal. The battery switching method comprises: receiving a signal corresponding to a predetermined temperature that is output by a BMS in an analog manner, the predetermined temperature being a temperature corresponding to a voltage that is output when a to-be-switched-to battery is switched to (S102); and performing temperature compensation for a constant-current source circuit according to the signal corresponding to the predetermined temperature, to adjust an output voltage of the constant-current source circuit to a preset value to implement an operation of switching between a current supplying battery and the to-be-switched-to battery. By means of the method, seamless switching between a current supplying battery and a to-be-switched-to battery can be smoothly implemented, without the need of any modification to a direct current power supply system, which brings relatively high switching efficiency and greatly improved system performance, and resolves the problem that the processes such as upgrading and commissioning are complex and require a large amount of work and high costs when the direct current power supply system needs to be modified, upgraded, or commissioned before interacting with a BMS. |
