Abstract

This thermoregulation system (1) for an electrically driven vehicle (V), the vehicle comprising at least one electric machine (E), at least one battery (30), and at least one power electronics component (37), comprises a coolant circuit (5), a pump (7), coolant heat exchangers, connected to the coolant circuit (5) so that the coolant may circulate through them and comprising a main exchanger (9), configured for exchanging heat between the coolant and air coming from the outside of the vehicle (V), at least one battery exchanger (11), configured for exchanging heat between the coolant and said at least one battery (30), and at least one secondary exchanger (13, 36), configured for exchanging heat between the coolant and said at least one electric machine (E) and/or said at least one power electronics component (37). The coolant circuit (5) is divided in a first branch (B1), which comprises the main exchanger (9) and the at least one battery exchanger (11), a second branch (B2) 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 (PB) to which the pump (7) is connected, the pump branch (PB) 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 (PB) is formed by a mix of the coolant circulating in the first branch (B1) and of the coolant circulating in the second branch (B2), and is directed towards the first and second branches (B1, B2) downstream the pump (7).
