A thermoregulation system for an electrically driven vehicle, the vehicle comprising: - at least one electric machine, and - at least one battery for storing electrical energy for powering said at least one electric machine, - at least one power electronics component, the thermoregulation system comprising: - a coolant circuit in which circulates a coolant, - a pump for circulating the coolant, - coolant heat exchangers, connected to the coolant circuit so that the coolant may circulate through them and comprising: - a main exchanger, configured for exchanging heat between the coolant and air coming from the outside of the vehicle; - at least one battery exchanger, configured for exchanging heat between the coolant and said at least one battery; - at least one secondary exchanger (13, 36), configured for exchanging heat between the coolant and said at least one electric machine and/or said at least one power electronics component, characterized in that the coolant circuit is divided in: - a first branch, which comprises the main exchanger and the at least one battery exchanger, - a second branch which comprises the at least one secondary exchanger (13, 36), the coolant being circulated in parallel in the first and second branches (B1, B2), and - a pump branch to which the pump is connected, the pump branch being connected to the first and second branches (B1, B2) by an upstream and a downstream connection points (P1, P2) so that the coolant circulating in the pump branch is formed by a mix of the coolant circulating in the first branch and of the coolant circulating in the second branch, and is directed towards the first and second branches (B1, B2) downstream the pump. - at least one electric machine, and - at least one battery for storing electrical energy for powering said at least one electric machine, - at least one power electronics component, - a coolant circuit in which circulates a coolant, - a pump for circulating the coolant, - coolant heat exchangers, connected to the coolant circuit so that the coolant may circulate through them and comprising: - a main exchanger, configured for exchanging heat between the coolant and air coming from the outside of the vehicle; - at least one battery exchanger, configured for exchanging heat between the coolant and said at least one battery; - at least one secondary exchanger (13, 36), configured for exchanging heat between the coolant and said at least one electric machine and/or said at least one power electronics component, - a first branch, which comprises the main exchanger and the at least one battery exchanger, - a second branch which comprises the at least one secondary exchanger (13, 36), the coolant being circulated in parallel in the first and second branches (B1, B2), and - a pump branch to which the pump is connected, the pump branch being connected to the first and second branches (B1, B2) by an upstream and a downstream connection points (P1, P2) so that the coolant circulating in the pump branch is formed by a mix of the coolant circulating in the first branch and of the coolant circulating in the second branch, and is directed towards the first and second branches (B1, B2) downstream the pump.
