The embodiment of the invention provides a battery cooling system, an electric vehicle and a control method, and relates to the technical field of electric vehicles. The battery cooling system provided by the embodiment of the invention comprises a cooling main circuit, a first cooling branch, a second cooling branch, a first cooling pump and a second cooling pump. The first cooling branch and thesecond cooling branch are arranged in parallel with each other and are simultaneously connected with the cooling main circuit in series to form a cooling loop. The first cooling pump is arranged on the first cooling branch, so that liquid is supplied to the first cooling branch through the first cooling pump to cool a first battery. The second cooling pump is arranged on the second cooling branch, so that liquid is supplied to the second cooling branch through the second cooling pump to cool a second battery. Due to the fact that the cooling pumps are arranged on the cooling branches, coolingof the corresponding batteries is achieved, each cooling pump only needs to meet the liquid supply requirement of one cooling branch, the requirement can be met through the cooling pumps with small flow and lift, and cost reduction is facilitated.

    本发明的实施例提供了一种电池冷却系统、电动车及控制方法,涉及电动车技术领域。本发明的实施例提供的电池冷却系统包括冷却总路、第一冷却支路、第二冷却支路、第一冷却泵以及第二冷却泵。第一冷却支路和第二冷却支路并联设置,且同时与冷却总路串联构成冷却回路。第一冷却泵设置在第一冷却支路上,从而通过第一冷却泵对第一冷却支路供液,以对第一电池进行冷却。第二冷却泵设置在第二冷却支路上,从而通过第二冷却泵对第二冷却支路供液,以对第二电池进行冷却。由于通过将冷却泵设置在冷却支路上,实现对相应电池的冷却,因此冷却泵仅需满足一条冷却支路的供液需求即可,从而使用较小流量、扬程的冷却泵即可满足需求,有助于降低成本。
