<p>Disclosed are a system (100) and a method (400) for supplying power to a battery heater (310) in one or more battery modules (110). A first DC electrical signal derived from an AC source (140) or a second DC electrical signal derived from a DC bus (150) is used for supplying power to a battery heater (310) of the one or more battery modules (110) in dependence on a voltage level associated with the first DC electrical signal relative to a voltage level of the second DC electrical signal.</p> |
