eBikes

With the growing demand for eco-friendly transportation, electric bicycles (eBikes) are becoming increasingly popular. Certain countries have even passed laws to encourage the adoption of eBikes. For example, China has decided to stop issuing new licenses for gas powered bicycles and now only issues licenses for eBikes. Many of these new laws also set weight requirements for lighter bikes, creating the need for smaller batteries and highly efficient chargers. To meet this need, PI offers charger solutions featuring its broad range of highly integrated, high-voltage ICs.

Design features include:

• Current limiting and thermal shutdown (with automatic fault recovery capability) to improve reliability
• Frequency jittering to reduce EMI
• High switching frequency significantly reduces the magnetic size
