The invention discloses a battery
liquid cooling system and a method for filling
antifreeze in the battery
liquid cooling system. The battery
liquid cooling system comprises a cooling unit, an
antifreeze filling tank and at least one
exhaust pipe, the cooling unit comprises a circulation pipeline and a water pump, the liquid chamber of the
antifreeze filling tank and the water pump are sequentially connected in series on the circulation pipeline along the circulation direction of the fluid, the air inlet of each
exhaust pipe is connected to the circulation pipeline, and a first control valve is connected in series on the circulation pipeline upstream of the antifreeze filling tank. By connecting the first control valve in series on the circulation pipeline upstream of the antifreeze filling tank, the efficiency of antifreeze filling is accelerated. The method for filling antifreeze in the battery liquid cooling
system closes the first control valve, connects the
exhaust pipe, exhausts the exhaust
pipe to the outside, starts the water pump, and under the action of the water pump, the antifreeze filling tank fills the antifreeze into the circulation pipeline, after a period of filling, disconnects the exhaust
pipe, and after the liquid level in the antifreeze filling tank no longer drops, opens the first control valve to complete the filling of the antifreeze.
