A heat transfer system 200 for a vehicle having a battery 104 and an electric motor 101 is arranged so that heat generated by operation of the electric motor is transferred to the battery. This arrangement enables a wheeled vehicle comprising the heat transfer system to operate more efficiently by heating the battery, and hence increasing the available energy that can be discharged from the battery, particularly in cold weather. Preferably, the heat transfer system 200 includes a motor heat transfer arrangement 201 and a battery heat transfer arrangement 202, with heat being transferred therebetween. Fluid heated by the electric motor 101 may be transferred from the motor heat transfer arrangement 201 into the battery heat transfer arrangement 202. In alternative embodiments, the heat may be transferred from the electric motor 101 to the battery 104 by other methods, e.g. using heat exchangers (figures 3-5). The heat from the electric motor 101 may be derived from the motor itself and/or from a control device for controlling operation of the electric motor. |
