Proposed California Bill SB-233 Mandates Bidirectional Charging for EVs to Advance Grid and Climate Protection

Driivz

The bill, SB-233 , aims to advance grid resilience and protect the climate by using EVs as “batteries on wheels,” tapping their stored energy to balance electricity supply and demand rather than bringing high-polluting peak generators online. Vehicle-to-building works much the same way but on a larger scale.

As this proportion grows, however, the basic dilemma associated with these renewable energy sources remains: first, electricity cannot always be supplied when it is required and second, on sunny days and in high-wind conditions, there is often a lack of capacity for storing the energy generated.

If the traffic becomes more congested (especially therefore in urban areas) or the road becomes more winding, the regenerative braking settings are available to the driver. The battery is then charged from the grid at a power level of 2.3 D1, D2, D3. A completely depleted battery is recharged in this way within nine hours.
