<p>A device for managing electric braking power includes a continuous bus, a dissipation branch, a current sensor, a controller, and an electronic charging switch. The bus includes a first pole for connection to a vehicle electric traction machine, a second pole for connection to a battery, and a connection point for connection to the dissipation branch, which includes an electronic dissipation switch connected to a dissipation resistor. The current sensor and the charging switch are positioned on the bus between the connection point and the second pole. The charging switch controls a flow of current over the bus from the first pole to the second pole. When power sent over the bus is greater than a total of power that charging of the battery can absorb and power that the dissipation resistor can dissipate, the controller causes the charging switch to open.</p> |
